Received my new Stiletto yesterday. Assembled everything according to Manual. First Test run on (two) 2s 5300mah 25c hardcase today. My first impression of this boat is FANTASTIC. Drives better than I expected. In stock form runs pretty fast. Boat has alot of potential. It turns in both directions equaly great and it feels like it on rails at speed. I would like to thank Darin for designing such a beautiful boat. I still need to trim and tweak, but out of the box very impressive. My first boat out of the box that didn't break on the first run. Pro Boat got it right!

Andy,

Motor is an 1800KV version of the BJ26 motor. More RPM, a little less torque. ESC is a 60A.

Which props are best is still up in the air for me at this point. I'm liking what I saw from and X440/3, that's been backcut slightly and pitched up a little, but I'm still playing with it.

Looking forward to reports of what you guys think work.

MM is the esc under rated,a 1716-10-50/2 round eared and 1.5m back cut. The 440/3 would get out the hole but get run down in the straights?? 1616-10-50/3 with same treatment would be worth a try

Is this hull going to be available without the leg, esc, radio. Something like a pro package steering set up included but add your own esc, leg, motor, radio ??? This would be great as a lot of us would like to try the hull out but do not want the expense of gear we would not use with full on race set ups?? I think this would be a valid and profitable exercise

If the hull does not like a lot of lift I have found rounding the ears with some spoon/cup at the tip with a back cut very beneficial.

Typical Aussie moron, there is no radio just an RX..read the specs. I doubt that it will be offered as a hull only, but you never know...the copycats will be all over this hull.

After running my new Stiletto, I have found that the throttle between 3/4 and full makes no change to speed. Using a spektum 3S. Does the Throttle Travel need to be at 0 and trim at B25 to get 100% throttle? I'm running with B100%. Batts are new 2s 5300 25c.

The throttle might need to be "calibrated" by:
holding the trigger at full throttle, plugging in the ESC, waiting for the beeps and then releasing the throttle.

New Stilleto-I just love the looks of this boat/quality is excellent. Little programing is all it needs, I think!

I tried calibrating the transmitter. Same 3/4 throttle. I ordered a programing card. Feels like the boat was programed to the Logarithm mode described below? When set to Logarithm mode, the ESC
delivers 45% power at half throttle and
80% power at full throttle. The Logarithm
mode is suggested for first-time boaters.

Question? The hatch attaches with two dowels in the front. After a run when I remove the drain plug some water comes out (not alot but enough) is this normal ?

Can the Stilleto handle a grimracer 42x55 metal prop?

simo71
09-06-2010, 09:09 PM
I wonder if you adjust your EPA on your radio to 120% if that would help? If it is how you mentioned, I see that as an error on Proboat's behalf...Most people who have purchased this boat would have experience & proboat are making you purchase a module that would only be used once to change the one setting, the throttle curve.

ALD

I put some clear silicone in those holes on mine, then pressed it in with the dowls. I'm not sure if they are totally sealed or not from the factory. They should be, but ???

I also sealed around all of the water lines on mine, and around the wires. They pass through double-hull sections, so if any water gets past them, it can get down inside the hull.

Mine stays dry inside now.

Id ask Darin ( the designer of this boat ) if there are setup tips for the ESC.

Oh well, I knew this was going to happen... I chipped the gelcoat on the tip of the left sponson. :crying:

Don't ask me how since I have NO idea, I didn't see the missing gelcoat when I got her out of the car, so I must have hit something at home. :doh:

I'll try to get some supply at a local marine supply store. Any suggestions for a gelcoat repair kit? Should I use just gelcoat paste? Or epoxy? What about color matching? :help:

It's a small chip, about the size of a small bean.

Thanks.

Darin, can you confirm the preset throttle curve for the ESC?

I've never heard of one being preset to the logarithm mode. In fact, I've never even used one in that mode. I can ask, but I'm certain it does NOT come pre-programmed in that mode. Should be linear.

I have noticed that the "steps" in the ESC are pretty large. Running at full throttle, then lightly backing off, results in a pretty decent drop in throttle. Typical RTR throttle curve.

ALD
09-07-2010, 04:35 PM

ALD... I really don't think that "beginner mode" is necessary for most people... in fact, on a tunnel, it may make it tough to balance the boat in the turns.

For the Stiletto, on the stock setup, I'd set the programming like this:

Battery Type: Lipo (assuming you are using Lipos)
Cutoff Voltage: LOW
Cutoff Type: Slow Down
Brake: OFF
Timing: LOW
Throttle Curve: LINEAR

Try that and get used to running the boat. If your temps are good and all is happy, then you can try the HIGH timing setting, which MIGHT (jury is still out with this boat) give you a little more zip...

had first run on smooth water.....ran great but no 40 mph for sure..... still needs motor angle and hight adjusted to a better position.....darin can u take a pic of your motor hight mounting screws pls and the angle of the motor? that would really help me......funny thing happened to me as i flipped the boat powering it up across its own wake......current going out....its a swim or just wait for it situation....i pull the throttle and the prop is touching the water and i power it in(about 20yds upside down...now i know it didnt do the motor any good underwater but will oil the barrings etc and hopefully it will be fine as i ran it for 5 mins after that and ran fine.....

will these take full speed turns?

Darin Jordan
09-08-2010, 04:02 PM
will these take full speed turns?

In stock trim, certainly... flies through the turns...

When you start proping up, and get it up to race speeds, you have to do a little more balancing in the turns. Basically, ease off a tad to set it into the turn, then squeeze it back to full throttle, easing off here and there if it starts "flying" in the turn (pushing to the outside).

That's just been my experience thus far, but mine is still not quite dialed in to a comfortable place for me to drive it. Also, that's a description of trying to drive a race-course, with 35' radius turns, holding lane one. If you turn a little wider, you can flat-out it. What can happen, however, is if you set it down too hard entering the turn, and try to add too much steering input too quickly, it can grab the outside sponson and tumble/roll to the outside.

Takes a little setup, timing and finisse to get it just right, which is part of the fun, and frustration, of driving tunnels... :thumbup: :cursing: :rockon2:

simo71
09-08-2010, 06:09 PM
I think thats why people enjoy racing tunnels so much. Watch some footage of the F1's (1:1) & they have the same response if a driver is being over aggressive when entering a turn etc.

Darin has giving a great answer about full speed turns with an O/B tunnel hull. This hull or any other O/B tunnel hull requires you to DRIVE the boat. This hull type isn't like most others where you can "throw" it in to a corner and expect it to sling shot around with out upsetting the hull. Racing these hulls WILL teach you how to manage your throttle thru the turns and teach you how to set up a boat. If your set up is a little off you will know it. However, once you hit that sweet spot.... man-o-man these tunnel hulls are a blast to drive and race...

Later,
Mike

Ok folks. I have made several runs with the stiletto and found that this boat instock form can not due 40mph. Without a GPS I would guess at around 30mph. Being fairly new to boats and tunnels this speed is perfect to learn how to drive a tunnel. Anything faster at this point for me, would be frustrating. Spin outs in turns etc. I re-programed the ESC and calibrated my DX3s. This boat is so much fun to drive and learn at a relaxing speed. I'm sure in time, I will upgrade motor/esc/ prop for speed, but for now, great boat and lots of fun!!!!!!!!!! Test made using 4s 2pack 5300 25C lip"s.

When I ran it last weekend I noticed mine was a little slow as well, but I thought I didn't set the motor angle properly. That was with an X440, I haven't tried the stock prop.

I just finished applying the first layer of gelcoat to mine, hopefully it will be ready for Sunday!

BTW, I've found other areas of the sponson where the gelcoat is slightly raised and if I gently press on it it flexes, I guess it didn't adhere completely to the fiberglass, I wouldn't be surprised if other cracks were to 'magically' appear on those spots.

Something to check on your Stilettos I guess.

Tunnel boats are very hard to setup. I just received my Stiletto and looks very well built. I was not looking for the fastest boat on the planet, just a very cool looking F1 tunnel with what appears is a neat outboard power source and not some apendage that is but ugly.

ALD
09-11-2010, 01:49 AM
Yes, it is a very cool looking boat. I trimmed mine according to the instructions. I tried trimming the motor up (away from transom) a little and that was a huge mistake. boat fliped and very unstable.Taking awhile to learn how to drive. I added a lot of expo and cut the travel down on steering and I find that setup to be very forgiving. I use 4s lipo 2pack so unable to adj cog. I think a4s lipo single pack would be a better fit for adjusment.

There were some minor scratches around the area, I believe I did scratch it and that made the blister break and the gelcoat come out. The fiberglass under the chip looked nice and clean.

I've fixed it now and I'll be more careful, if any more gelcoat comes off without reason I'll contact them and see what they can do.

I was just wondering if any of you guys have noticed any "blisters" on theirs.

I was the one that mentioned the X440 and that's the only prop I've tried since that's what I had available, I haven't tried the stock prop and I have ordered a X437/3 but I'm not sure when that will be here.

What do you suggest? X642? Darin mentioned good results with the X440/3...

BTW, I'm ok with the current speed with the X440. I wanted to try the stock prop but it's not sharpened/balanced and I then I had to fix the gelcoat... :cursing:

First thing I did; to grease the flexshaft. No issues there, but still running with the teflon tubing.

Just to be clear, I don't know how fast it goes, I'm sure it would be much better with a X440/3, but I'm not the one complaining about the speed.

It's fast enough for me as it is. At least for now. :thumbup1:

I'm more concerned about the gelcoat coming off, it's a :cursing: of work to fix and I'd rather spend my time doing better things that getting intoxicated by MEKP (yes, I used proper protection :smile:).

What prop are you running?

Can you take a side view photograph (close up is great) showing the height of the prop and the angle it's at?

What cells are you using? How new are they?

What part of NJ? I moved from Phillipsburg (I-78/US-22 @ Delaware River) about 2 years ago.

Guys... First... this hull is NOT gel-coated... that's white paint. Very heavily laid on, white paint.

As for speeds... I did some bench testing of the motors this weekend and found some interesting info.

The testing was done with the following setup:

Battery: 4S1P ThunderPower 45C 5000mah pack
ESC: Castle Hydro 240
Timing: 0
Load: 6x3.5" Plastic/Carbon Airplane Prop.


Under this test setup, the motor actually registers 1885KV, and a little over 31,000 RPM unloaded. With the load (airplane prop), the motor dropped to 1703KV, just shy of 27,000RPM, pulled 35.55Amps, and the output was 562 Watts.

For comparison, the Geico motor registers 1460KV and 24,100RPM unloaded, and 1399KV, 22,500RPM, 18.84Amps, and 304Watts with the SAME load.

What this tells us is that the price for the additional KV is torque, so you will NOT be able to turn the same large props. It's more like the UL-1 motor, where it climbs in WATTS quickly as you add load, so you need to turn a smaller prop, with less pitch.

This actually puts the Stiletto setup more inline with the Nitro equivalent, so working with props more similiar in size to what they would use is in order. I tried an X440/3, pitched up slightly, and backcut about .030"... slightly cupped as well. Motor temps were very reasonable (around 108), so it can handle more, but I will increment it up slowly, because my race props for my BJ motor get the motor temps up to dangerous levels and overheat the wire leads. Speeds really aren't appreciably faster either. Just adding load to the motor.

SO, play around with some of the smaller props and see what you come up with. I'm thinking something in the 40-42mm range will be a good place to start, though the 37mm 3-blades might be workable as well.

As for setup. Set the stub shaft centerline about 1/8"-3/16" above the sponson bottoms, neutral or just SLIGHTLY up angle (aft higher than front to lift the nose), and start from there. I prefer it to be dead neutral to start, so as not to have the prop height change as the unit steers. Mine seems to work best with the 4400mah or 5000 mah pack, mounted all the way forward, and I also added 1oz of lead to the nose. That's the setup in the video posted in my Race Prep thread, and the boat is certainly breaking 40mph there (I'm estimating more like 45 or so)

SLOW the steering down, lower the throw as well. You don't need much to get this to turn. Then learn to balance the throttle.

Hopefully this gives you a good place to start from. Let me know how it goes.

ON the Stiletto, YES, there is still should be room for a pair of 5000's like that. If they aren't too long, you can lay them end-to-end in the bottom. You may find the weight works out better if you stack them toward the front, however.

but should not happen

There is no magic bullet that keeps flexshafts from breaking. I've yet to break one in three years of running OPC, but it can happen and does.

USUALLY, it's a case of it being installed incorrectly, OR from the prop being shocked numerous times by hopping the boat a lot.

To check to make sure the first isn't an issue, the flex shaft should float between the coupler and the stub-shaft slightly and should NOT be tight end-to-end between those two. In other words, when it's installed correctly, you should be able to push the stub shaft in and out slightly.

If you follow my race prep thread, you'll see a picture of the inside of the lower unit, explainging a method to make sure for proper fit. There are production tolerances that sometimes come together to make this not happen from the factory. Doesn't hurt to be informed and take a few minutes to make sure everything is setup correctly.

As for the hopping... People seem to be having some fun running these in 4" chop... more power too you, but an OPC is designed to run in fairly smooth conditions. They are NOT rough-water boats, so do this at your own discression...

You should be able to use any standard length K&B 3.5 style shaft. The ones from the Bullet Drive, that Steven sells here on OSE, should work as well. You MIGHT have to fit them, however, which may involve trimming a tad off of each end, but otherwise, they will work. Might be a better quality cable as well.

=AndyKunz;228621]What cells are you using? 4s 2pack 5000 40c thunder power pack-stacked in front. Boat handles great. NO top end speed, programed esc to linear setting. How many cycles on them? 5 cycles. I have tried everything I know to the Radio settings and bought a program card and between 3/4 and full throttle nothing. Just tops out at 3/4 throttle. All settings set to Darin's suggestions and it has inproved the handlling of the boat. I also tried a 40mm prop 3blade. Performance same as stock prop. I believe that the ESC is not giving me 100% throttle or the stock flex-shaft is causing to much drag or thats all this boat will go. One thing for sure is the esc in linear setting is 0% thru 75%. Battery and or different props or settings has no effect on the throttle. Anyone change out stock ESC ?

For those of you who are finding you not getting 100% throttle, try increasing the throttle travel to 150% I have done this with the motor pulled from the leg & peak revs have increased, this was my personal finding.

This is with the Dx3s & does not mean it will work with other transmitters.

Increased speed with new setting. I would say w/o gps maybe 35mph. Very fast for this boat and easy to conrtol. Great looking boat, runs really great.

When I'm recommending props like this, I'm recommending them for RACING applications. As such, you sport boaters need to keep in mind that a race only runs for about a 1 1/2 minutes or so, and mostly at full throttle (even in the turns). Sport running with these setups will likely cause the boat to get warmer.

Also, my 440/3 is back-cut about .030" and detounged slightly, so it doesn't have the blade area, lift, or blade loading that a stock one would.

Keep an eye on things when trying these setups and build up to them...

With the X440 (2 blades) I can go to LVC and the wires get to ~120F at the end, heatsink on the ESC is ~100F and caps are about ~130F.

This is with 2x 2S 5300mah Turnigy hardcase (these are really 2S2P 2650mah) mounted vertically in front, side to side.

I'm using 5.5mm bullets on the batt side, I still need to change the motor side.

Darin Jordan

You'll have a lot less resistance going to 5.5's instead of those Deans... In fact, I usually cut off the Y-harness, and just use the red and black wire, then series together the batteries themselves. Any resistance you can eliminate will mean more runtime and less heat.

On the motor wires, if they are getting warm, you might want to open up the front of the motor cover some to allow more air to circulate around the motor. I did this on mine and it helped a lot.

I would never use a raw prop... especially an Octura. Wait for a sharpened/balanced one.

In the meantime, a Grim/ABC 42x55 is also a good prop. You can bend some more pitch into it slowly as you build up to speed...

Knowing nothing about working over a prop I take it a grim needs work also before use

The Grim props can generally be used for general use right out of the box. They still should be sharpened and balanced, but can be run as they come.

Beryllium Copper is nasty stuff... :eek:

If you're going to work on props just make absolutely sure you're protected, this means goggles, respirator (not just a simple mask), gloves, long sleeves shirts

And make sure you clean the area and wash your clothes right after you're done.

The guide here on OSE is the best I could find: :bowdown:

PS: But I should add: the warning at the bottom of the guide should really be at the beginning, including suggestions on how to protect yourself.

I made two runs yesterday with the 42 X 55 prop. I should have given more detail. I have 5.5mm bullets on everything. I ran the boat for 4min each time. 4s 2p 5000mah 40c thunderpower lipo's. Full throttle except I slowed way down in the corners (chicken effect). My heat index for electronics was high, ESC 142 batts 128.My connectors were 172 deg but hold up fine at that temp. I also live in Arizona and it was 106 degrees that day. No temp on motor. I thinking of running without the motor cover for a run and see what the temps are with 42 x 55 prop.

Seems like your running a nice set-up good choice on the batts and run time and good job with the 5.5's. Due to the heat outside maybe cut the runtime down by a minute on such a hot day and disconnect the bec and run a rx pack my help. Are you running 1 lipo or 2 paralell?

I'm running 2s 2pack in series. Stacked toward the front.

If your going to run 42 x 55. I would advise cutting holes in engine cover and 5.5 connectors everywhere. When you use your throttle start real slow.
The boat is a rocket. I cut the steering travel to 90% and used 20% expo. Have not tried turning at high speed yet. I also tested boat with stock sharpend/balance prop and ran much better and little quicker. Easy to learn on. The big prop is scary fast but down the straights tracks true.

I've taken your suggestions and added them. Thanks. Here is how it reads now.

Warning- Potential Cancer hazard!
Take caution when working with Beryllium Cooper! Activities such as grinding, sanding, polishing or any activity which abrades the surface will cause airborne dust particles. These Beryllium Cooper particles are highly toxic! There are dangers involved with inhaling dust or fumes. It can cause serious, chronic lung disease in some individuals. Over time lung disease can be fatal!

If you're going to work on these propellers make absolutely sure you're protected, this means proper eyewear, a high quality respirator (not just a simple cloth mask), gloves, long sleeves shirts. Immediately after your work is completed, proper cleaning of the your work area is also suggested.

Well, he prepared 2 props for me too, I didn't ask, but I assumed (and surely I hope) he uses proper protection when working on them.

I would feel horrible if anything were to happen to anyone just for my hobby! :eek:

I'm running the x440/3 prop and having good results my deans get a little warm but no problems,all I did was buy the prop and put it on with no modification.I run 2 5000 2s packs stacked in the front for best results,boat is still a little slow but hey it is stock got 41mph!

Just make sure you stop to let everything cool once in a while,I don't run it full all the time.My run time is about 10 minutes total

i have two sets of batteries the one that got hot has about the same gage wire as the esc..the ones i ran today had much larger gage wires maybe that helped......ill run the 440 again with this set and see...i know the 440 ran much faster then stock prop...waiting on my 642 prop from chuck to give it a try....it works wonders with the mg they say..

I've got a couple of short clips running a Grim Racer 40x52/3 prop, I'm glad I managed to take them before the flex shaft broke. :huh:

I'll see if I can post them tomorrow.

Since I'm still waiting for the last packs to finish charging I thought I would post one of the clip on YouTube. :biggrin:

BTW, the size of that pond is about 100m in that direction, by my calculations I'm leaving about 10m or so at each end and covering the rest in about 4secs.

So we have ~80m in 4 sec = 20 m/s = ~45 mph give or take.

Can't wait to see what the x437/3 de-tongued does. :bounce:

Laddie, that is a big mistake, Octura props must be ballanced and sharpened as documented by Darin. Also 3 bladed props are a bear to ballance
