you esc its set with brake, you need to programing the esc and disnable the brake, the its run free

 S T E K A 264 points

it´*s to heavy and big the CG will be to much in nouse

 sfactor1 945 points

it is perfect for the dogfighter! just use 7x5 sports prop and a 5s batt big enough to balanc. you may have to carve a bit of foam. just look at rcgroups. this motor has had good results

yo construi el peregrine, con 5s and 7x5 230k/h mucho cuidado, es muy rapido

 fariasda 1 points

7x5 , 5 s 3000mah 25c, more the 140mph in the peregrinne, be careful is very very very speed

 cmarines 12 points

did you find the answer? my shaft is bent and I need to replace it.

 Frank77 270 points

Depending on which ESC you use, on 5s and 6s it runs best with timing set to High or 26 to 30 degrees and PWM at 16kHz. If you are running 3s or 4s you can probably get a way with the timing set to medium around 15 degrees and PWM at 8kHz. This motor has 10 poles so set it per your esc manual for a high pole motor

 david 13 points

Thank you very much Frank, that was a big help.

 Frank77 270 points

The motor rating above says 1600watts. Your 2750 watts is 1175watts too much. Your lucky if it hasn't disintegrated yet!!!!

 k1nouri 2 points

haha, they always rate these motors lower than what they are so people dont burn them, I have over 70 flights with this setup and its just bullet proof,

 P3K33 2 points

What PWM and timing settings Are you using???

 k1nouri 2 points

I am using HK 200 amp esc with standard setting, didnt change anything, just plug and play.

Check out this video from RCFoamfighters... www.link can take quite a bit... I have the same set up in my scratch built Fun Jet but still waiting to get it up in the air again. I need a new battery first. I had it flying on a Super Mega Jet on a 3 cell and it made it to 100 mph.

 DownUnderPilot 97 points

You can run this motor in short bursts to 90-100A, but be careful! I have my own design plan which does 180 MPH with 6S and a 5.9x9 prop. Current is ~90A in flight, and when used in short bursts the motor comes down warm.

Check the temperature of your motor on landing - is it hot to touch? If so I'd expect it not to last too long.

 waterlogged 2542 points

What's this ???? Answering your own questions. No credit for this one ?????

 CHAMP-RC 1051 points

I thought of something to add to my question after i wrote it so i added it do the discussion. Answer my question or go away fool.

 waterlogged 2542 points

I thought Tony was supposed to ask the questions. So he can credit you. That's no way to talk to anyone by the way, it's so unsociable.

 sfactor1 945 points

does waterlogged actually think u can credit yourself? lol

 waterlogged 2542 points

Not that it's any of your business and you had nothing to do with this question. In fact you haven't a clue what's going on. So I would ask you to not make smart comments when you don't know the facts. But just to prove you're not as clever as you seem to think, YES this ID was crediting himself. How, I won't go into but I will add that he was partly responsible for the 20 cent credit being dropped. OK, now kindly stop mking comments regarding me. Thank you.

 CHAMP-RC 1051 points

sfactor1 im not entirely sure but he seems to have wayy too much time on his hands LOL. I just needed help with some dimensions of this motor...

 sfactor1 945 points

waterlogged....as a member of this site, the credit system IS MY BUSINESS and is EVERY OTHER MEMBERS BUSINESS. yes, i am well aware of kellyann. everybody is. only a moron doesn't know what he did. u cannot credit yourself with THE SAME ID so u r obviously not as clever as u think u r. YOU also had nothing to do with this question . did u answer it? NO! i have just as many rights as u to answer whatever questions on this site as i please. now why dont u stop telling other members what to do and STFU

 waterlogged 2542 points

Would you mind writing in English please. There is no need for stupid SMS type abbreviations to be used. This is a forum, not a mobile phone. Obviously you refer to yourself as a moron because you don't appear to know what was happening. Kellyann was indeed crediting himself. Using a little intelligence you may understand. Kellyann registered himself under a number of false names. Those false IDs are therefore considered to be Kellyann because he wrote the question using one of those false IDs and then, using his kellyann ID he answered the question. The false ID aking the question then credited the Kellyann ID. Obviously that would mean that he credited himself. Nobody else was involved were they? You appear to have far too much time on your hands attempting to take me to task on what I post. Maybe you would spend your time more wisely by reading what is posted a few times before making comments attempting to make you appear superior. Because at the moment you're looking rather foolish. Maybe finding someone with equivalent intelligence level to pick on may help. It appears you are way out of your league at the moment. You're becoming a Troll and not a very good one either.

 waterlogged 2542 points

Also, please keep your foul mouthed comments to yourself. There is no need to use them here.

 CHAMP-RC 1051 points

WOW get a life! Seriously its beyond a joke now. That must have taken you like 2 months to write.

 sfactor1 945 points

not sure what's wrong but that is NOT normal!

 waterlogged 2542 points

Actually it could be normal if the ESC was faulty, or you were running too large a prop or maybe running the motor flat out for long periods, or your prop is way out of balance, lack of air flow past the motor or the motor's shaft being out of balance, faulty windings. It maybe a combination of any of these that could cause a motor to overheat. You say you're running low voltage. With a 5s fully charged you could be using 21 volts. Id hardly call that "low volts" also how did you get the reading of 30 amps? Up to 21 volts at 30 amps, flat out would tend to warm a motor up but not burn it out unless one of the above is involved.

 sfactor1 945 points

since when is a faulty esc considered normal? by definition, something that is faulty cannot be considered normal. "faulty" is an abnormal state. f something isnt supposed to run, then when it doesnt run, it is acting normal and working perfectly as it was designed to and therefore NOT faulty. faulty and normal are contradictory terms and something cannot be both at the same time

 sfactor1 945 points

well....something/somebody can be faulty compared to others and that could be completely normal for them. but a faulty esc is not normal

 waterlogged 2542 points

Smart A, I never said a faulty ESC was normal, but the P3K33 asked if it was normal for a motor to get hot. I answered that "Yes it could be normal if the ESC was faulty" Absolutely nothing wrong with that statement and is perfectly understandable to a person with the mental ability to understand English. As it would also be considered normal should a car's cooling system boil if the thermostat was faulty or perfectly normal for a plane to crash should it's wings fall off. Instead of going off like an idiot you should spend a little time and brain matter trying to understand what is being said prior to the schoolboy attitude. Life is full of contradictions. "Normal" people with reasonable intelligence would understand that. Actually I have a box with roughly 15 ESCs in it. Every one of them is damaged. Therefore it's perfectly normal for any ESC within that box to be faulty.

 waterlogged 2542 points

I meant to mention, I will not be answering any more of your rantings as to date I found nothing of note worth reading, simply childish attempts to humiliate me and what I post.

 Christian 203 points

You need an INRUNNER motor for your boat, this in not suited for rc boats.

 Huey_205 1 points

you can get water cooled motor mounts that might help you out. Christian is right not really a boat motor but since you already have it its worth a try. Just watch your prop size and monitor your temps

 waterlogged 2542 points

I would advise a new inrunner with a water jacket for cooling. The interior of a boat is supposed to be watertight therefore it's airtight as well so there is no air circulating to keep things cool. You could buy a motor mount with a cooler built in but this only keeps the front of the motor cool. You may get away with it if you don't push it too hard. I'd certainly go for an inrunner to be sure. I assume you are running a cooler for your ESC. That's just as important.

 Brian 1 points

I have this setup in my Funjet running 6s with 7x5 prop and I have the Turnigy dlux 100A SBEC Brushless Speed Controller w/Data Logging ESC. Also I would suggest an AMP meter to test how many amps your system is running to be sure you are not putting too much on the ESC. I design my power systems for 1.5xconstant amps I will draw. Ex: system that requires 80Amps constant will need a 120Amp ESC. This way on burst current you still will not overload the ESC. Hope this helps!

 k1nouri 2 points

I have this same setup and pulling close to 120 amp, how long have you been running this setup ? am I risking ?

 aaron2233 528 points

yes its pusible but it whont last as long on a 4s but you can try it for shore dont no how long it will last but yes have a try hope this helps you

 P3K33 2 points

Do you mean that the motor will wear out sooner using low voltage? Or do you mean the flight time will be shorter on 2s??

 aaron2233 528 points

the motor whont wear out but you whont get a very long flight time but for all means you can try it hope this helps you

 BossJay 159 points

You can use 2s lipos. Prop size 10x8 or 11x6.to be on the safe side,Check your set up with a watt meter.flight time depends on the capacity of the lipo that you will use.

 P3K33 2 points

Thanks that's helpful! So cuoting a prior reply the lower the voltage the shorter the flightime than high voltage with the same given amp rating on batteries?

 BossJay 159 points

It's the amp consumption of the motor that will dictates your flight time. Higher amp consumed(more power on the throttle)less flight time, less amp consumed(less power on the throttle)longer flight time.If you are planning to use higher voltage lipo's 3s,4s or 5s You must change prop size.I use 5s 2200mah 40c lipo's and my prop size is 7x4 flight time around 5min.with throttle control.

 sfactor1 945 points

for the same amount of amps, the higher the voltage the power it consumes therefor a shorter runtime. a 2s setup for example is 7.4v x 50amps = 370watts. a 3s example for the same amps is 11.1v x 50a = 555watts. naturally 555watts will drain a batt much faster than 370watts on the same capacity batt

 eddy_s 8 points

You can try this www.link and diameter are the same.

 Roman 33 points

I run it on 6S, but 7x5 propeler max. It pull oround 110A in peak, then amps drop around 90A. You must heve good cooling. I tested graupner speed prop 6,5x6,5. It pull 70A, but battery was on low. I testet again.

 sfactor1 945 points

10x6 on 6s??? maybe 300amps! just a guess on the amps but it NOT a good idea.

 sfactor1 945 points

better to use the 12mm 90blade fan. its scott's favorite!

 danikronos 660 points

this engine is quite heavy for glider has a much lighter engine, no more 100 g and power about 300 watts is sufficient

 Andrew 7 points

This motor is capable of putting out in excess of 1500 Watts of power!! with a 7X5 prop. Using on a speed plane. Check out Rcfoamfighters**** they are using this same motor.

 sfactor1 945 points

a pylon racer type glider!

 monkiee 23 points

I have this on my "Funjet" ultra with a 85amp turnigy ESC and wow!!!!!! she is like a rocket on 4 cell, 1400W!
