sv 27 motor

[mr.mauian]

:doh: I can't seem to locate where I saw it but what is the sv27 motor rpms ? say at 14.8 volts. Any info will be nice and very helpful, Thanks.:D

[kavvika]

I believe its 1800kv, so multiply that by the voltage you plan on driving it at to find rpm's.

[whiplash]

26,640 rpm at 14.8 volts

[mr.mauian]

I kinda thought it was near 26,000 . hmmmm might have a secret surprise in my SV on Sunday.....hehe.

[mr.mauian]

Eh ! Tunda's Vegas ready yet ?

[Tunda]

hope to finish by sun im at work right now logged on with my psp

[SweetAccord]

It's 1600Kv. That is how Tower Hobbies has it in their specs in their printed catalog. They get info from Aquacraft according to their customer support. You won't see that spec online on Tower's site under the Vee's Specs or the motor's specs but will find it on their online catalog.

[mr.mauian]

Thanx SweetAccord, It might be cool to fit a 13 xl in the SV27 just for the instant accelleration......hmmmm might need some airplane wings attached to it...lol.

[SweetAccord]

That would be sweet. Maybe turn it into one of those Air-Boat R/C's? Well, I have the AMMO motor, wish I had a boat to put it in. :confused1:

[SweetAccord]

Well I finally got my boat but I will be doing other mods to it first.

[SweetAccord]

In the meantime, I'm wondering if a 2600kv Ammo motor would be a better choice than the 2300kv in the SV27? I read that the 2600's are being used for drag racing which is what I'm all into. Also wondering is the stock ESC will take on the 2600kv with no issues or would the X-Power Brushless 70a Esc be a nice replacement to match up with the 2600kv?

Anyone have any suggestions?

[Darin Jordan]

Anyone have any suggestions?

The 2300KV Ammo is pushing the limits of the stock ESC... I'd definately upgrade the ESC if using either of the motors mentioned...

[SweetAccord]

Would you say the Product ID: xpo-blb70a X-Power Brushless 70a ESC is good enough with IB4600's?

[Darin Jordan]

Would you say the Product ID: xpo-blb70a X-Power Brushless 70a ESC is good enough with IB4600's?

I can't say for sure... I don't have any experience with that ESC...

If it's rated at 70a... I'd think it should work fine...

[Avanti]

I have run the 2300 and 2600 ammo on my stock esc with no issues to date.
that is not to say that you won't but I think you will be fine on the stock esc for a while.

[RCprince]

One spike with that 2600 on that SV esc and kaboom...and there might be some collateral damages to like your lipo's I should know trust me

[SweetAccord]

No Lipo's here. Just NIMH for now. So it's a 50/50% answer huh. Ok. Avanti27 says it's ok, RCprince says no. Hmmm.....

[Avanti]

I run nimhs

[SweetAccord]

Uhuh, so I'm wondering what the issue RCprince had then?

[RCprince]

we killed one lipo and blew the esc, we were running a grimracer 45x68 along with the ammo 2600 and 2 2s 3300

[SweetAccord]

So would the GrimRacer L44x66 prop have been a better option to get away with and not blow anything?

[RCprince]

Those props are too big...right now I'm running a Fiegao 9l( 2731 kv) X637 with 5s on an EP1 and out running any SV you can bring my way

[Steakhouse]

Those props are too big...right now I'm running a Fiegao 9l( 2731 kv) X637 with 5s on an EP1 and out running any SV you can bring my way

Ok, on 4s you would be over 40,000 rpm. The Ep1 and the feigao arent even close to being efficient enough to run that for more than a couple passes without melting something. 5s is as feasible as the bridge im gonna sell you. :laugh:

[Avanti]

the prop was your problem not the 2600

[RCprince]

Ok, on 4s you would be over 40,000 rpm. The Ep1 and the feigao arent even close to being efficient enough to run that for more than a couple passes without melting something. 5s is as feasible as the bridge im gonna sell you. :laugh:

We drag race...no time for circles the earths already spinning, Steakhouse bring your SV we'll be in Valdosta (Thur 17 April - Sun 20 April) for the SV open class...who laugh last laugh the best ;-) mums the word.

[RCprince]

Avanti I knew the Prop was the Problem I kept telling him to prop down...then kaboom green smoke of death

[Steven Vaccaro]

Would you say the Product ID: xpo-blb70a X-Power Brushless 70a ESC is good enough with IB4600's?

You will easily be pulling 60 plus amps. That's way to close to the maximum rating. I would run a minimum of 100amps or greater.

[ReddyWatts]

Using a Y537/3 prop can lower your load by 10 amps with close to the same speed over the X637 prop. Just another option. I noticed Steven has started selling it.

[Steakhouse]

We drag race...no time for circles the earths already spinning, Steakhouse bring your SV we'll be in Valdosta (Thur 17 April - Sun 20 April) for the SV open class...who laugh last laugh the best ;-) mums the word.

That does sound like fun. :iagree: Any motor in the Supervee? I ve heard that they blow over if you try to push them hard. Cool:thumbup1:

[RCprince]

Just gotta take the time to balance her out....

[RCprince]

Are you serious Reddy...hmm how about the 632 I'm gonna get me a 537..10amp could be the make or break point also...thats good to know

[SweetAccord]

I believe that I wish to be in the same kingdom as the "RCprince". So as a follower what all is your setup to get these speeds? I all into drag racing too. Going in slow circles is not my cup of coffee either with all due respect to all. So my question is out to the "RCprince".

Ok so would the X-Power Brushless 100a Esc be a good match with the Ammo 2600? Or is there a Feigao that would be a better equivalent? If yes on the Feigao, which one exactly? How long are the runs on the Ammo 2600? What ESC are you using?

[RCprince]

oh yea, much due respect to those who do ovals they are the fore runners of the sport... thats a giving, they make sure the equipment is up to par. my cousins use to gas oval back in the day with riggers and picco 80's and 90's it was lots of fun I'd watch and enjoy and have fun...but i'd let you in on a secret I could,nt steer a herd of sheep...I'd swipe everyones boat, So i'll stay with my strength...SAW...(Straight And Wideopen)

[RCprince]

Sweet that Esc with that 2600 and 2-2S's or 2-6 or 7 cell should get you above 48 easy...try a 640 or 642 max....

[SweetAccord]

Thank you! So is that a good ESC? What are you using?

[RCprince]

a Phoenix HV110

[SweetAccord]

Yikes .... $229.99! That is almost the cost of a whole new boat! Is the X-Power Brushless any good or should I penny pinch and get the Phoenix?

[RCprince]

not sure , you'd be better off getting a hydra 120 in that case

[SweetAccord]

So the X-Power is not any good? Any experience or heard anything with them?

[RCprince]

I'm not saying it's bad, maybe some of these guys heard of it....most of these guys run the hydra 120 as an upgrade for 2-2s's or 14 nimhs

[SweetAccord]

Thank you RCprince!

OSE sells them so I figured it was commonly being used. Can anyone chime in on the X-Power products?

[SweetAccord]

Ok I got the Castle Creations Hydra Watercooled 120 ESC for $154.99, also purchased the AMMO 2600Kv. Well there goes some of my $600.00 tax relief! So with that, I'm not going to pursue the X-Power product. :)

[RCprince]

Where did you get that ammo from...everywhere I look there out of stock..I need a couple more..I like em

[SweetAccord]

Ordered from Tower Hobbies. It's on back ordered to Feb. though. That's ok though with me as I have the AMMO 2300Kv in hand. :)

[Steven Vaccaro]

Just a fyi, the ammo's are 2 pole motors, far different than the 6pole stock sv motor. I have been selling the sv guys L size motors which are a direct comparison to the ammo 2300. If you want some mind popping speed a feigao xl is the way to go.

[SweetAccord]

So I should be good with the Castle Creations Hydra Watercooled 120 and the AMMO 2600kv? Any starting prop suggestions?

[RCprince]

I'd say between a 640 and a 642 max

[SweetAccord]

Sweet, Sweet! Thank you for the prop. info. So what about the ESC good enough for the AMMO 2600kv??

[RCprince]

Steve I wanted to try an XL in my out Board But I'd have to drill out the drive dog in the motor I'd rather a 3.2mm shaft thats why I went with the 9L

[SweetAccord]

Lost me, I thought this was a SuperVee posting area?? I think Steve is referring to a SuperVee application? :)

[RCprince]

LOL..Yea Steve is the God of this forum so he gets to go where ever he pleases...It comes with the territory :biggrin:

[SweetAccord]

Well then Steven, maybe I'll get one then. So what Feigao XL motor do you recommend for "some mind popping speed" to match up with the Hydra 120? I will be using NIMH's. Remember this is for a SV. :)

Thank you all for your input, everyone!

[SweetAccord]

Where'd you go Steven? Which L are you recommending?

540 6L 4,096 RPM / Volt 5mm Shaft
540 7L 3,511 RPM / Volt 5mm Shaft
540 8L 3,072 RPM / Volt 5mm Shaft
540 9L 2,731 RPM / Volt 5mm Shaft

I'm waiting to place an order with you. :)

Also any reason to stay away from the XL's?

[Steven Vaccaro]

sorry I've been short handed the last few days.
I would recommend a XL motor. The xl's have more mass and torque. I have had many guys run 8xl's. the temps of the motor and esc will be much lower. more rpm is not always a good thing. It took me a while to understand that, but when I finally did, I stopped burning so much stuff up.

I'm running a syncron with a 8xl and x646 on 4s for sprint running at in the low 50mph range. So far so good.

[SweetAccord]

Ok great to see you are still alive!!! Heheheh, so not the L's now, but the XL and the 8XL specifically? So I have the Hydra 120 will be running 4600 NIMH's and you feel the 8XL Feigao in a SuperVee is a maximum setup? I want to be sure this will be the best setup for drag racing before I place an order. You see I was informed that an AMMO 2600kv can be used in the SV. You recommend the 8XL.

I'm confused you see since the 8XL is only 2,084 RPM and the AMMO is 2600kv, so it this 8XL going to be slower or is this not a fair comparison of the two? Will there be any disadvantage of the XL over the L as they are larger like you said, will the runtime be shorter than the equivalent L?

Sorry to be a pain, I hate to order and then return.

Thanks!!

[RCprince]

the XL has more torque than the ammo so in theory and practice you'd run more efficient lower amp draw, lower heat build up larger prop. but your running drags short runs...:confused1:

[SweetAccord]

So what should I get with this setup to run the SV27 at it's maximum capability of the hull design? I can always adjust speed with ESC and prop. sizes right? In other words what is the best Brushless runnable motor that anyone can run for this hull design? So far the highest value I have been told is the 2600kv. Is that the limit?

Will it be anything like this or faster??

http://www.youtube.com/watch?v=pTZCMnNdhbU&feature=related

Thanks!!

[RCprince]

It's trial and error...Time, CG, Prop...Lipo's... effort

How hast do you want to go? There is really no reason to put a Ammo 2600 in a SV unless you just want short straight line passes.. JMO. I have had SV27's for a couple years now 2 different ones and both I left the stock escs and motors in.. I ran both on 2S2P lipos and S&B M445 prop, I get 42-44mph all day long with this set-up. No heat issues, never had anything "smoke" on me. The boat is very unstable (pushing the limit on handling) in oval race water at 42-44mph..

[SweetAccord]

Ok that is what I wanted to know. But somehow RCprince is using a 2600 and running it successfully. How is that so then? Yes! I do want speed but and but not to hurt anything. Fast passes and being able to run with no major issues.

Any ideas still?

[txboatpilot]

You can run the Ammo 2600 with a smaller prop than the m445 I run. Just run very small prop to start with, watch your temps and go up in prop size to gain more speed. Start with something like a CF40 and go from there.. Just watch the HEAT!!!

[txboatpilot]

What motor are you running now?

[SweetAccord]

RcPrince is running a 2600, so the hull is capable. Is this the limit?

[txboatpilot]

Capable, YES.. Limit YES..

[SweetAccord]

I have the stock SV motor, the AMMO 2300 and the 2600 on order. Steven claims that the Feiago's, my impression by him, are faster?? The XL in particular, stating that the XL has more torque than the L. So what is the advantage and disadvantage between the two of the same KV?

[txboatpilot]

If you want a 60+MPH motor look at a 1515/1.5D (2700KV).. Run that with a M645 and you will take FLIGHT!!

[txboatpilot]

The XL with the same KV can spin a bigger prop with less heat..

[SweetAccord]

Ok now we are talking.....

[SweetAccord]

So the XL will be faster pound for pound over the L with the same KV with less heat? What about run time? Shorter? Which KV is the ideal one? The 8XL?

[txboatpilot]

What speed have you got out of the stock motor? What props do you have?

[txboatpilot]

Run time will be shorter(not much), the xl will take more mAh from the batteries.

[txboatpilot]

Ok now we are talking.....

Sometimes this stuff is hard to get a hold on! I will try to explain the best I can..

[SweetAccord]

I don't have a GPS or aything to be honest for accurate speed values. Did you see the YouTube post I did? That is a bit faster than mine. I have 440/3, 40x53,40x52/3, CF45, CF48, CF40.

[txboatpilot]

The thing you need to look into is lipo's that will increase your speed more than anything..

[SweetAccord]

Ok I want to be able to drag race basically. I just want to run the limit of this hull design. I have the Hydra 120 and will be running 4600 NIMH's. I can run any prop really that is recommended.

All I would really like to know what is the motor that will make this hull design scream, but still make it runnable? Any ideas? I have the 2300, the 2600 AMMO. Steven stated the Feiago's are fast if not faster is the impression I'm getting.

So my posing question, maybe you can't answer, what will be the better motor, a L or XL. Steven says the XL. Another person says the L. What is the advantage and disadvantage of each in the same KV rating?

Also which would be the optimal motor KV to select that will allow a high prop. run fast and not heat everything up and allow me to tune it down, if need be?

I just don't want to get a motor that is useless and non runnable with any prop that I can fit on the 3/16 shaft and then have to sell the motor off. I wish to get the advise that is right on.

See where I'm coming from? Once again maybe you can't answer me, but I'm putting my question forward.

I'm willing to want for now to get the most out of NIMH, Lipos down the road.

Thank you, I really appreciate you helping me on this!

[txboatpilot]

If you want to drag race you are wasting time with your HEAVY batteries!!!Drag racing is about "KEEPING IT LIGHT"!! Lipos will give you a 4-6mph increase with any prop or motor!!!

The 2600 will make your SV SCREEM!!

Now that I know what you have and want to do, we will get you set!

Start with your 40x53 and then go up to the CF45 and CF48..

[SweetAccord]

WOW thank you, so of these Fieago's:

540 6XL 2,779 RPM / Volt
540 7XL 2,382 RPM / Volt
540 8XL 2,084 RPM / Volt
540 9XL 1,853 RPM / V olt


Which would you get? I want one more to spare/different motor.

Thank you kindly!!

[txboatpilot]

I run a Rigger with the 1515/1.5D (2700KV) and X640 on 4S1P lipo and get over 60mph easy in a straight line..

[txboatpilot]

Try the 7XL.. It will fly on 4S lipo...

[SweetAccord]

I won't be using Lipo, will that be an issue?

[txboatpilot]

Only issue will be knowing that there is more SPEED and you cant get too it!!!! LOL

[txboatpilot]

Do you have a extra 2300 Ammo, I need another for a twin set-up I am working on?

[SweetAccord]

I only have the one 2300. Sorry. :(

Hehhee....I have EP4600 which are Trinity EastPowers. They are pretty high rated. So the SV can run a 540 7L 3,511 RPM / Volt 5mm Shaft
with a Hydra 120 ESC (120AMP) with no issues? Unless I go prop crazy maybe like the CF48? Any run time estimates?

[txboatpilot]

You should be happy, just watch the props! Run time is hard to est. With all these motors you have bought, you should really look into lipos! They are night and day from NMHI... Read the last issue of boat modeler mag. Jay Turner has a great article on the diff. in lipo power vs. nmhi......

[txboatpilot]

Metal props dont flex like CF props, so you might stick with the 40x53..

[SweetAccord]

Wonderful. I was under the impression that the 2600kv was the running limit for a SV motor in that hull. Now that I know a 7L 3,511 RPM will work too, sweet!

I just got all the batts and chargers, so down the road I will, i figure the batteries can be the last push, once I make it run as fast as possible on NIMH's the Lipo's will be the nitrous!

Do you know someone that runs that 7L 3,511 RPM in a SV?

[txboatpilot]

That is 7XL not 7L!!!!!

[SweetAccord]

Oops you right, sorry, I meant the 7XL. So the 7XL 2,382 RPM / Volt is the one. Is this one slower than the AMMO 2600 due to the Kv rating or is the XL cause of the length and torque compensating for that?

[txboatpilot]

If you are going to run in a straight line, remove the turn fin! It causes drag, and will free up 1-2mph..

[SweetAccord]

Remove turn fin.....writing that one down. Man this is gold, anything more?? I'm eating this all up!! You great!!

So is the 7XL slower than the AMMO 2600 due to the Kv rating or is the XL cause of the length and torque compensating for that?

[Avanti]

you will need adjustable tabs if you don't already have them. taking the turn fins off make the SV very unstable. (however adding the port turn fin is not worth it; if you ask me the only thing it does is make left turn even worse) check out my speed thread if you have not seen it yet. I have some more tricks up my sleeve I have just ran out of desire to mess with the SV right now.

[SweetAccord]

Where is your speed thread? You have a lot of posts. Have the URL please please? What would you recommend as the fastest motor that can be run in the SV? 6XL?

[domwilson]

I say try the stock power with a S&B X642 with lipos. I think you may be pleasantly supprised. Throw in some adjustable trim tabs from here and be even more surprised after you get it dialed in. While you're ordering the trim tabs, get an OSE water jacket for the motor.

[SweetAccord]

domwilson , I have the turn fins the water jacket already. No trim tabs yet. I won't be using Lipos as yet. I just want a Feiago motor suggestion that I believe has been answered? So far the 6XL is workable. What do you think? Any experience?

[domwilson]

The 6XL might work. I'd start with a x637 and watch the temps. The 6XL is a hot motor and will have a higher amp draw which could damage batteries if they aren't up to it. I have the stock motor (for now) with a X642 with lipos and it gets pretty hairy at times. I have an Ammo 2300 or maybe a Feigao 9L w/100 amp ESC that is waiting to go in it with a X640 prop. Just not up to swimming right now to retrieve the boat. :laugh:

[SweetAccord]

Kewl thank you!!

[domwilson]

I heard of some people adding a weight to the front to keep it from going airborn during high speed passes. That might help once you get it all put together. It's a real balancing act.

[txboatpilot]

If you over prop the 6XL, you will SMOKE your batteries or even the Hydra 120!!!!!!!! You need to do some testing!! Your choices in motor KV are going to get you a lot of SMOKE!!

[Steven Vaccaro]

I think we are confusing drag racing. Are you going to make one or two passes and bring it in? Or make many passes until the packs die? If its the second, that's not drag racing in my opinion. The reason I suggest the xl is because the motor has more metal in it, so it takes longer to over heat. Its more forgiving than a smaller motor. if you are strictly running for drag(1-2 passes than check your temps), you want to run the smallest motor you can, than a L size will be better.

[Avanti]

Where is your speed thread? You have a lot of posts. Have the URL please please? What would you recommend as the fastest motor that can be run in the SV? 6XL?

http://forums.offshoreelectrics.com/showthread.php?t=1956

[SweetAccord]

Yes Steven, I will drag racing till the batteries are dead. :) So does that change your answer now? Which is ideal the L or XL and what KV?

Man I really appreciate all the help here!

[SweetAccord]

Avanti27offshore, thank you I eventually found that thread after finding where to search a users threads! Thanks!!

[SweetAccord]

Ok so which then since 6XL is out?

540 7XL 2,382 RPM / Volt
540 8XL 2,084 RPM / Volt
540 9XL 1,853 RPM / Volt

Another question please (am I a pain?), are these slower than the AMMO 2600kv? Or is that not a fair comparison as the XL are longer so there is more torque etc.? I'm starting to think maybe the XL are not ideal as for the same RPM they draw more give more torque, which I don't think the torque is critical as the boat is not a weight monger and for the same RPM the L is way less draw and higher RPM.

Guess I'm trying to figure out what everyone has done with the SV. Are they using higher kv motors and proping down? or Using smaller kv and proping up? or using XL and using higher KV and proping down? Is anyone using anything else rather than the Ammo 2300 kv in a SV and successfully running it I guess is my $100.00 question. :)

[domwilson]

Not neccessarily. It's a balancing act between speed, runtime, amp draw. The XL's offer more torque so you can run a larger prop with less heat issues. For a given prop size, a higher kv could mean a higher amp draw. If the batteries cannot provide the high amps, the available voltage will drop thus reducing the motor speed and increasing the heat. Running a larger prop or higher kv motor will not always increase speed. A higher kv motor will "bog down" if the amp draw exceeds what your power system can provide. A lower kv motor can reduce amps on a smaller prop but you will see a reduction in speed if it doesn't provide efficient thrust. So you have to balance prop size with the motor and available power. That's not taking in consideration hull size, design, weight and operating conditions.

[SweetAccord]

Well I finally figured out that the stock motor is capable of 41,000 RPM at 18.v. So a 2300kv AMMO at 14.V, the RPM would be less RPM about 32,600 RPM. Interesting that most feel that the hull has it's limits, not that I'm doubting that everything does, but it's interesting that the capability of stock motor allows for the motor to run at a higher RPM than most are running in an aftermarket upgrade 2600kv and blowing over.

Interesting...just pondering.

[domwilson]

RPM's and KV ratings are only a part of the overall picture.

[SweetAccord]

I know, I was waiting for that answer "RPM's and KV ratings are only a part of the overall picture." ....hehehee..

[Steven Vaccaro]

Not sure where 41,000 came from. Most estimate the stock motor is 1600-1800kv, which is in the 30k range at 18volts.

[domwilson]

:ohmy: Good eye!:iagree: I didn't catch that one.

[SweetAccord]

Ok 32,400 RPM. Sorry, sorry. Was looking at another spec value on another motor.

[SweetAccord]

Well I will be getting the AMMO 2600 and the Feigao 8XL. One has torque, one has the speed, so it will be interesting to see with a 440/3 how each handles in the SV.

[domwilson]

Have you looked at the L series motors from Feigao? The 9L and 10L motors are pretty good and hold up pretty well. Steve carries those here.

[domwilson]

Plus they're purple and look really cute.:tongue_smilie:

[SweetAccord]

Ah, cute motors, that's what I need!!

[SweetAccord]

Plus they're purple and look really cute.:tongue_smilie:


So which of these Feigao's do you run...what is your setup domwilson?

[Monsterbrad]

Ok
A buddy has this boat i have ha villian and he flipped it in a pond and it took a diver to get it from about 10ft down.
Team Orion 4500's ok
Speedo still try's to program when you plug it in and the motor does nothing
I have a new motor on the way
Do you guys think it is junk???
Oh yes on another note the boat sat in the pond for 2 days before the diver my brother could get to it :w00t:

[Monsterbrad]

My buddy sunk his boat and it sat for 2 days before we got to it under water.
A diver had to get it (my brother) in 10 ft of water.
The speedo acts like it wants to work beeps and all and responds to the arming set up but the motor does nothing
Ordered a new motor
Is there any way to save the old motor???

[SweetAccord]

It would depend how you think it looks. Is is corroded, rusted? Is it still under warranty? Not that it would be covered, but maybe AQ would rebuild it at half the cost? They have been very generous to me on things, bu that was under warranty. For the cost, you better off getting a new one. Any pics to evaluate?

[RandyatBBY]

I have sunk several boats over the years and got them back at the end of the race. The rotor will be a little pitted but will still work, the whole motor needs to be sprayed with WD40 and can be saved if you did not burn any of the insulation off the windings. Bearings may need to be replaced too.
