Well I did a kick ass job with the new dual pickup rudder and cooling system upgrades. So let do a little more!

New Turnigy 180 marine ESC, Leopard 4082 1500Kv & Cooling jacket.

Fits in there all nice and snug dont you think?

After doing the new rudder and setup I was able to keep the stock traxxas 36mm 1600Kv motor and ESC cool. Well under 90*F. So I felt I should have no problems keeping the new motor and ESC cool as well.

It will be interesting to see how the hull rides giving the side to side roll we have seen on this hull with the extra speed & torque that you should get with this set up esspecially if you put bigger props on. Lets hope the weather improves soon. Thanks Martin.

Yeah I'm worried about that myself. In my other runs I had that problem at higher speeds sometimes. But I noticed battery placement helped. Also it didn't do it all the time. Seemed a little induced after hitting wakes. Still sucks tho. I'm going to try strut angles, props, trim tabs and battery placement. If I can't get it dialed in for good handling over 50. I think I'll just put the stock stuff back in it and sell it. Then use the stuff I bought towards another cat. Those genisis cats might be fun

Come on down Larry your welcome too. You can crash on the couch in the basement. Down there where I tinker on stuff. Bring a mini revo if you have one. I have a ramp down there too lol.

I've got some really nice lakes for running here. About 20 or so miles away.

02-03-2011, 07:27 PM
I think the hull could benefit with either wider trim tabs are an extra set to get them closer to the strut because when the boat is at high speed up on the v theres no tab in the water. The tabs on the boat also look a bit on the short side as well. Thanks Martin.

JPriami
02-05-2011, 01:57 PM
So i hit 50.3 yesterday testing it. but I had to use an m445. i didnt have much luck with the prather 220. but my gps was acting up so I dont think the speed readings i got from the 220 were accurate.

http://img.photobucket.com/albums/v337/Jpriami/Traxxas%20Spartan2/b203ebfc.jpg

The boat was still wanting to chine on WOT passes. I guess I will try adjusting the strut a little and maybe give the tabs a few turns down.

I wanted to ask do you guys think the stock traxxas servo of 80oz is enough for the rudder? I was wondering if the rudder could wiggle and cause the boat to act like its chine walking at wot.

martin
02-05-2011, 03:39 PM
If you look at most deep v boats around they use much wider tabs that go much closer down to the strut, When thats up on the v theirs no tab in the water. Thats also not a very powerful servo for a boat that size doing 50+ mph. Are the temps much lower now than with original motor & esc

Great, so the m445 worked out! The prather is just too much prop.

Do NOT put tabs closer to the keel. It will create even more lift in the transom in the straits and induce more chine walk.

martin
02-05-2011, 06:42 PM
The reason i said tabs further down towards the keel is i have a 15" mono deep v that runs 45mph & was getting chine walk to the point it would put the boat in. To the point i was practicaly destroying the boat each time it went in hiting the bottom of the lake. The boat did not have tabs at all, So i added a set down towards the strut & it has stabalised the boats chine walk but still has its speed. If the waters a bit rippley it will still go in now & again but not to often but on flatish water its stable where as before it would go in even on flat water where the chine walking completally upset the trim of how the hull ran. But this is on a 15" hull though. Thanks Martin.

Speaking of the boxes...................i went into my crappy local LHS...................i wont mention their name but the intitials are Hobbytown USA, and saw one Spartan sitting on the shelf. Asked the guy about it, he could care less if i had dropped dead, and I said "can i see the boat out of the box?" Well it was in a plastic wrap..............He said no, we cant open it. I said "What?.every other boat in the store is opened except this one." I have opened many boat boxes there, how do you know what you're getting otherwise............... I said "ok, then i'll just pay you for it, open it here, then return it right now", he told me it had to be in the original unopened packaging..................and I told him, "and thats the way its gonna stay as long as no-one is allowed to see and feel it"...............Traxxas wants it that way i bet.

BTW, these guys at Hobbytown USA could easily get a job in a morgue................i have given them too many chances to be kind and helpful..........they are complete idiots.

ive got to just quit using that little camera on my rc's. i swear every time i use it just about on whatever vehicle there is an accident. This time the boat did a few flips. Camera stayed on. but it messed up the video so nothing got recorded.
GPS said 57MPH today. I dont know if i believe it or not. I think it was a fluke. so im not boasting that one till I reproduce it.
still got the death wobble. but its inconsistent i can make a few passes at wot and it rides right and wont wobble. seems to be when i gradually get up to speed it rides better

my temps were 60/65 on motor and esc. it was about 50 outside today

Ive been thinking a lot about the chine walking issue. I tried to adjust the tabs but all that did is the boat seems to run with more of the hull in the water at high speed and its still chine walking.
It looks like the boat wants to twist (right side drops down) from the torque from the motor & pushing the prop into the water. I was wondering about weight placement. What if I stagger the batteries so that one of them on the left is up further so that it might be harder for the boat to raise that side. Or maybe I should put the GPS on the left side to add a little extra to make it harder to lift that side.Or should i drop the right trim tab down more to help push that back up? not sure about that solution though.
Its an odd problem because its inconsistent. I have been able to make some high speed passes without chine it just gets on plane and goes good. Seems that if i ease into wot it does better too. So i feel that something is exciting the chine and once it starts it dosent quit till you drop the rpms down.

Brushless55
02-07-2011, 07:58 PM
I place my gps on the left side and I think that helps my SV out

martin
02-08-2011, 10:03 AM
With the Spartan the weight inside the hull is distributed pretty much even i think, This dosnt help with torque roll. I know with the self righting boats theirs a lot more weight on the left side looking from the rear along with the flood chamber as well so theirs quite a lot off biased to the left. This seems to help reducing torque roll with this type of boat. Thanks Martin.

Rumdog
02-08-2011, 01:36 PM
This boat suffers from chine walk, not torque roll. Most all fast monos do since the ride right on the very rear of the hull (ride pad) if set up correctly. Weighting the port side will not change this. Prop walk comes into effect when propping to big for a give hull. Then it will tend to pull the starboard side down toward the water. The teeny prop on the Spartan isn't effecting it's handling.
The larger props JP is using may be causing prop walk however. Try adjusting just the starboard side tab a little bit negative and run the port side neutral. Or, try a prop with less pitch(lift).

With regards to the stock heat issue i have found that traxxas say there products can do something and they arent fibbing they just dont seem to be able to do it for long, take my rustler vxl for example, it says it can do 70mph with a 3s lipo and the right gearing- yes it can but for real world use around the street the heat it generates is unreal! so for day to day tyre bashing its no good and i would imagine its the same sort of thing with the spartan.

Misleading at the very least.

I'm not sticking up for Traxxas, nor am I saying their hype and claims aren't over stated, but in reality this is nothing new in the marketing world.

Watch any Ford/Dodge/GMC pick up truck ad on TV and they all claim to be the toughest, most reliable, longest lasting pick up on the market, all the while showing video footage of them bouncing over boulders, rooting through mud with the tires spinning and throwing mud every which way, and then jumping the front end 2 feet in the air coming out of a ditch at the construction site. Yeah, you can do that a few times, but drive your truck like that on a daily basis and you will soon find out out how tough, reliable, and long lasting it is.

Or those commercials for those "certain" products for the ladies that show them swimming in the tropics, and riding horseback down the beach with big happy smiles on their face. Don't know about you fellas, but it don't work like that in my house. (well; maybe it would if I sent the ladies on a tropical vacation once a month, but they don't tell you that on the box)

Yes, it's wrong that Traxxas (and other companies) attempt to mislead us into believing their products will perform beyond what they are actually designed/intended to do, but it certainly isn't a new tactic.

It seems like everything about the Spartan has been a let down, but I'm thinking I can still have fun with my kids with a mid 40's 36" boat, as long as I can keep it from overheating without too much expense, and, if it proves to be reliable in the long run (which is debatable at this point, I know).

Some recommend going to the Leopard 5692 in this size hull to get around 60mph but thats mega expensive with motor a 240hv esc + big mods to custom mounts & much bigger shaft & strengthening the hull bottom. Id be happy with high 40s in this hull that would be at much reduced cost & considerably less work useing the 4082 motor & t180 esc on 6s but not sure if this set up would be good in this hull.

True, but I was just illustrating the general concept that most products are marketed with exaggerated/accentuated claims as to how wonderful they are.

We don't know that Traxxas hasn't successfully achieved 50MPH with the Spartan during development and testing with the out of box components installed. With a perfectly dialed in set up, perfect water and wind conditions, high quality packs, etc. it may well have been accomplished.

EPA fuel economy ratings on vehicles is a similar concept. Take a vehicle that has been thoroughly inspected and dialed in by a team of mechanics and engineers, on a flat test track with a perfect road surface, no wind, correct tire pressures, at a steady optimum speed, etc, etc, and vehicle manufactures can achieve their claimed fuel economy ratings. In the real world, we never see those claimed fuel economy numbers, but they still post them on the window stickers and brag about them on TV commercials.

Different set of circumstances, same basic concept.

I'm more concerned with the reports of torched ESC's and overheated motors. I can live with 45-48mph instead of 50mph out of the box, if the Spartan can prove itself as reliable.

Time will tell if failed components affect only a small percentage of these boats, or if the Spartan is destined to be a lemon.

Just my opinion.

they take the cars and trucks and run them on computers and take them out in the real world with real conditions!
they don't run with a tail wind and tires over inflated to get more mpg that you and I would get in the real world
not a concept but factual data

just would be nice if they didn't have the lame claims and had good stuff like AQ and PB :biggrin:

Bored bored bored. Waiting for the sun to warm it up out there. Decided to start looking at the boat as I do my helicopters. And factor in balance. I made a level spot to set the V part of the hull on. Put a bubble level on the hulls flat spots . Then placed the batteries and stuff in. And I've noticed the right side is a little heavier. Prob the rudder. Then experimented with placement of packs laying flat and on their side along with and without gps. Found some good base spots that make the hull evenly balanced as a new starting point for weight placement. Aparently it' been a bit out of balance this whole time.

Generally speaking... Monos tend to do a little better with a tad bit of weight offset to the LEFT... Helps to counter prop torque, and the drag/weight of the hardware on the right...

Thanks. I was thinking that would help. I was just suprised that where i thought it would be evenly balanced it wasn't. And where i had it balanced for more weight on the left it was really just about balanced even.

I didn't say tail wind, I said no wind, and I didn't say overinflated tires, I said properly inflated tires. i.e controlled conditions.

And if you think vehicle emissions/fuel economy testing isn't done under controlled test conditions, you are living in a dream world bro.

From the EPA web site:

Certification Emission Test Data

All new cars and trucks sold in the U.S. must be certified to meet federal emission standards. This is accomplished by performing laboratory tests on pre-production vehicles. Most testing is performed by manufacturers at their own facilities. EPA audits the data from this testing and performs its own testing on some of these vehicles to confirm the manufacturers' results. All of this test data is available to the public for review and analysis.

Note that it says laboratory tests, and at the manufactures "own facilities". That isn't real world testing.

The EPA performs independent testing on some vehicles. Admittedly, I don't know if EPA testing is done real world, or in an independent test facility.

Concept is exactly the same. Real world performance may not equal performance under controlled test conditions, and manufactures are going to accentuate positive data to sell their products.

We as consumers have the choice not to purchase if we feel the manufacture is in any way misleading or unethical, or if we feel the quality of the product is sub standard. We can also file complaints with various consumer advocacy groups should we choose to do so.

I don't have any hands on with PB, but I agree with you, my AQ products have proven to be excellent.

Just got to the lake and was about to test my traxxas spartan after a few adjustments & mods. It ended up just going airborne and flipped then turned into a buoy. Ripped the canopy clean off the boat. Good thing I installed flotation on the underside of it. Had to call a friend to bring me my paddle boat so I could go get it.
Next time ill pay a little more attention to the wind and not head into it when testing a new setup at wot.

Damages so far just seem to be a busted rudder servo. Drying out the electronics now then will test later.

I think that took off rather than hit something, It was coming up for to long before it finally went. Judging by how you can clearly see the spray coming of the prop being blown by the wind when the boat was first going away from the bank. That was going into what must have been quite a strong head wind when it lifted. Thanks Martin.

02-13-2011, 03:47 PM

Nothing to do with this crash but is it me or does the Spartan appear in the pictures ive seen of the transom to have a much steeper dead rise angle than most of the good deep v hulls around. What affect would this have on this hulls running characteristics if it turns out to be steeper. Thanks Martin.

Got to run today. It wasn’t to bad. I did jump out of the water hitting a wake but, at least it didn’t jump up and crash :D
I was able to run wot and make some really nice passes with no death wobble!
So balancing the boat (little heavier on the left) out seems to have really helped it.
Sadly I only hit 53.8Mph today with the M645 prop. I was looking for high 50’s :(. And 47mph on the M445 that I had previously reproduced a couple times a 54mph speed. Seemed odd.
I feel it’s a couple reasons (hopefully) something to do with the previous water crash and making it a buoy for about an hour and all the electronics got soaked to some degree. Even some was inside the esc case. I water proofed it a little better now. I think all the settings on the esc were wiped out. I didn’t think to check and reset them when I got the boat back together.
The other reason being I went airborne last time, this time I had the packs for weight up further in the hull. BTW I know this isn’t the main reason it didn’t death wobble because ive run with the packs there before and had the same wobble.
Now that I seen it go today and it ran nice, I will start shifting the weight back and see if it gets faster. If not maybe try adjusting the strut. I’ll be happy to get it finished so I can just go and run it with confidence on how it runs consistently. But then again it might sit on the shelf after that because I’ll need another challenge and something to mess with.

I just had a thought i need to test my gps too. It was soaked for that hour in the crash and didnt work for a while. I'll try it on the way to work tomorrow.

Hit 57.5 this morn b4 work. Moved weight back about 1.5 inches. But it's becoming unstable again. Going after work to try something else. Maybe try dropping the strut down to level. It's just slightly prop up right now. Or place the gps up front on the left. Idk. Open to suggestions.

I have a question.
So the boat seems to run stable with no bouncing side to side when the batteries are placed up front and about an 1 to 1.5 inches back. And it seems to like the prop pointed up a few degrees. Currently 54.4 MPH stable running

When I start to place the batteries further back it starts to increase the speed but also starts to bounce side to side. I understand why btw im just asking what other experience with this sort of problem and the solutions they found.

what would be best? leave the batteries up front where it runs stable or place the batteries further back and start to use the trim tabs to see if speed can increase and still be stable? I fear the tabs will just add drag and sort of cancel it out, thats my theory anyways

02-20-2011, 12:37 AM
Hey J, i found out after LOTS of testing that when the batts are back a bit, the stinger wants more positive......................tried it numerous times. One would think move the stinger down to get the ass up, but it doesnt work that way on my 39 incher..................go figure that out:tongue_smilie: ????

JPriami
02-20-2011, 12:48 AM
Pointing it up will force the nose of the boat up and push more of the hull out of the water. less hull in the water will equal less resistance. but it gets to a point its unstable\loose in any craft. Then theres a balancing act to fathom. If you point the prop down it will start to force the nose of the boat down into the water and you will get slower (in most cases). im starting to feel 54.6mph is about max for what i have atm. i heard you mention the x642. im worried the smaller diameter may not do much for me. but it might work too. I was thinking a prop thats still 45mm but more pitch. idk.. might just heat things up more. COG for it being stable seems to be about 9 3/4in up from the transom. anything behind that its becoming unstable. anything more than that slows it down.

JPriami
02-20-2011, 09:13 PM
Look what I found.
Alternate mounting holes for trim tabs molded into the transom. They just are not drilled out.
I noticed on the prototype that traxxas has that there were holes in the back of the transom closer to the strut. I figured it was just from testing different setups.

today I got the speed above 54mph to 55.8 but stability issues still rearing their ugly head. I can ease into the throttle and it goes on plane nicely. if i gun it or if its hitting wakes when getting on plane it excites the chine and keeps doing it.

Made some adjustments. Pulled 58.9 MPH 2 times off the GPS. Boat was running really well. I still have about 5% of an issue with chine walking. But it was dependent on my driving. If I gun it hard it excites the instability when coming on plane and keeps doing the chine. If I come up one plane with a smooth throttle response it just gets up and goes nicely.

I added a little bit of lift to the starboard side of the boat. It was an experiment of an idea I had. I planned on using the right trim tab down a little. But looking at the rudder I thought about using it to do it. Sound weird? I kicked the rudder very slightly forward, I had been running it just a little kicked back. because I visualized it being more level when the boat is on plane and slightly nose up. Now I think the very bottom of the rudder is acting like a trim tab under the water and giving the starboard side a little lift the way it is kicked forward a hair when the boats on on plane. Its working because I was able to move the batteries further back and it was still being stable with out chine like all the other times ive tried it. But it still seems to be better with the packs about 3" back from all the way forward. I didnt seem to gain much when I moved them back on one of the test today. I think the same can be done with the starboard (right) trim tab. And I may try it as well.

How did you mount your 180 Amp ESC.

It looks like you have it sitting on the top rail of the tray, what do you use to support/secure it in place.

Thanks
Kevin

JPriami
03-02-2011, 12:17 PM
I had used rubber. I had left over from a car restoration project. I cut it to match the shape of the esc. Had to cut two pieces to get the right height. Used 3m heavy duty trim adhesive to glue the two together. Then used 3m body molding stick tape to mount it to the tray and esc. It's pretty hard to get off. Even when it was submerged the time I buoyed it.

dag-nabit
03-02-2011, 01:31 PM
That is similar to what I was thinking.

I was going to try and find some lexan/plexiglass type material about 1/4" thick to cut to size and then epoxy or screw it to the bottom of the tray. Then use some thicker foam type (vibration isolating) double sided mounting pads, or velcro strips, to mount the ESC to the pad. It looks like I need to lift it just under 3/8".

I'm not sure how well epoxy will hold on the plastic tray. It has a lot of flex.

This is the best single shot. The outside holes are aligned. The stock trim tab is about the size of the single outside "new" tab and in approximately the same position. It hangs off the back of the transom in about the same position as the stock. The new tab essentially expands the width. I bought it from Kinetic. I don't have the part number but I believe OSE sells the same unit. http://i1197.photobucket.com/albums/aa425/shcaskey/IMG_0012.jpg

Here is some food for thought. Ive noticed some spartan owners that have upgraded boats say that their boats run well on 6S and are not chine walking. Then some that complain that they cant get it tuned out. Then im sure some of us have seen pics of crooked holes for mounting the hardware. I noticed my strut looked like it was slightly crooked in its stock location. If you move the strut up or down and its not dead straight it would kind of angle a few slight degrees to the left or right. I wonder if thats causing some of these problems?
When I get my new strut Im going to dead center it on the hull and see how it goes.

Hello Guys, Our engineers are looking into the reported issues and are certainly aware of your concerns. Reporting the issues you are having is one thing and there is nowhere on this board that says you cannot do so. Many people have already posted their boat issues and have had no problem with the Mods or management for doing so. Bashing Traxxas is a different issue altogether and if you cannot state your vehicle problems without flaming us then it is better that you do not post at all because I can assure you that we do have an issue with that. This is clearly stated, yet again, so I expect no surprise from anybody who receives infractions for flaming or Traxxas bashing.

If your referring to the stinger tube it is a little smaller. The stock strut held a .195 propshaft. The new stinger holds a 3/16" .187 propshaft. But the stuffing tube inside the boat to the motor is stock. For a .150 flex. But I'm running piano wire drive .078 into a .187 propshaft.

Nice Pictures and those shafts look cool. Is the plan to put a different Teflon sleeve or a smaller stuffing tube to take up the .072 difference in size or does that not matter? I thought(sorry about that) the wire might whip back and forth in the liner and maybe leak.

I ran 2 times today. Once in the morning then once in the evening. Both times with good results. Nice plane across the water at WOT. Speeds were pretty consistent between the runs 58.5Mph. Only instabilities were running over my own wake just right or when the wind would blow and make little waves in a certain area it would jump out of the water. I have some video but Im having trouble getting it up. I'll try to see if I can get the full video I made uploaded tomorrow.
For now I am making a clip to share that should be up shortly.

Ok, questions. The wire drive...where did you get it? I recall that someone might make them for the Spartan. Can a drive that is too long be cut down to the correct length? The Sppedmaster you got here, correct? Great job! Tra**as should contract your skills for their next project.

Yes got the stinger here on ose. the wire drive I got from Ben over at fightercat.com Jeff Wohlt makes them too rcraceboat.com They can be cut to length. Steve sells them too here on ose.

in the manual on trim tab adj. says angle tab down will force bow down. If prop torque pulls boat to the right then wouldnt you angle the left tab down some to drop the left side bow to compensate? i set mine that way and it seems to run stable as long as batteries are more towards the front. Anyone else try that?

the torque will twist the boat hull to the right. that can be adjusted a little by right tab down. Ive found the boat doesnt twist as bad if you ease into the throttle. If the boats twisting really bad & cant seem to be adjusted out it can be a sign of the drive cable binding. Ive seen it many times on these boats.

Are you using a teflon tubing inside your stuffing tube? What's the outside diameter of your stuffing tube?

I have the same .078 wire drive with 3/16 prop shaft on my Titan 29" that I got used. From the beginning I had to fix the leak from the stuffing tube. In my case the stuffing tube were a 5/32" brass for Octura .098 Flex Cable ... I guess by measuring it and had no teflon tubing inside stuffing tube.
Now I have to test a new idea. A two pieces stuffing tube with a silicone tube (2mm inside diam. and 4mm outside diam.) that fits tight on the .078 wire drive and on the smaller stuffing tube. It could have more drag and in that case I will go back with the original stuffing tube.

One last question: What bullets are you using on the motor wires? The stock 4mm bullets of my Leopard 4074 are getting too hot and I will try the EC5 5mm type.

No GPS to use yesterday. It got wet and quit working on me. But it's no doubt doing low 60's in this clip. And I cant hold the throttle down for long it gains speed and becomes unstable again. Huh go figure. Lol

Too cool the way it wants to jump out of the water when you pin it. Almost like your cat now.

What prop are you running in the vid??

I'm not telling yet ;) that was a raw prop I need to finish so it still needs to be balanced and a little better sharpening. I just wanted to see if it was worth me putting work into finishing.
