Some people say 55T is best for axial rock crawler, but for losi anything brushless 21t will be good. I use Traxxas Titan 550 21t and is awesome.

I already used it, and I burned my engine, can use some espped 6s, but not every engine can handle 22.2V.

I'm using this on 6S and no problem. My old 150A ESC broke though (not burned) but it was 3 years old. as long as you don't overgear the system there is no problem.

Dont use this for edf unless your good at replacing bearings!!!

Just one motor will be good. I have it on a 1/8 monster truck and it has lots of power

For drift you can use sensored motor,it´*s have over control aceleration.

overheat, you need to have a better esc

thank you for ur info i didnt notice the "CAR" until u mentioned i wil get the warhead instead *}

yes...1/8th scale or bigger. if smaller go a smaller motor with a higher KV. this is a monster.

i run this motor in my e-maxx and it has alot of torque. but compaired to a 4thousand kv it will be slower but more torque

this wont fit in your fan unit ,dia, to big

 KITSONCLAN 6 points

Yes this motor is suited to a 90mm fan definitely not won't fit a 64mm

 lummox 32 points

Turnigy 2615 EDF Outrunner 4800kv for 55/64mm would be a good one to try. i would also put a better fan in it, like the hoaye 7 blade and a larger esc probably 45-50amp. BAM!

 matt 3 points

yes its very powerfull and very very torquey. i run it in my e-maxx

 matt 3 points

yes i run this in my 3906 e-maxx with 4s on a turnigy 150amp and it has alot of power and torque

Yes, it will work, watch your temps tho, it's only a 540 size. If you want to go insane, buy two ESC's and two of these motors, use the stock motor mounts to mount the motors, program the ESC's for forward-brake (if you use reverse, you'l get problems with one ESC going in reverse while the other doesn't, so you'l fry your electronics) and run a 4S LiPo on each ESC. Throw in two 27T pinions and there you go! Extreme speeds and insane torque!

I tried this as a replacement motor for my 76mm Lander fan on 6S, it lasted approximately 4 seconds before the front bearing collapsed, I was just trying it out in my hand and had only got to 3/4 throttle. It might be fine for cars, where the bearing forces are different due to having a gearbox (the clue being the big word "CAR" on the side), but for EDF it should say "AVOID" on the side instead. Oh well, someone had to try it I suppose.

2-4kg car, boat or plane?

 juans 12 points

for example: 4s lipo, 100a car esc, 15,5kg servo and 2:1 gearing (pinion has to move 2 turns to turn once the main gear) all these to move 4kg model car fast (50-70 km/h) and a bit torque. P.D. If this motor can't, what motor should you recomend? sorry for my english, and thanks very much!

if you up the V it will burn out soon

Yes, the low Kv rating makes it good for crawlers.

 catorish 17 points

it is a bit quick for crawler,maybe with a 2 cell life battery..

Thanks for the information, Jason. Helped to decide if this is suitable to purchase.

Hi All,
Is this motor ok for 90mm EDF ? in 6S?

 vasy1 605 points

This should be ok on 6s, maybe even better on 7s *-)

 zeeek1 513 points

As Cptn. James T. Kirk once said: "For how long, HOW LONG?"

 vasy1 605 points

Depends on the quality. I fly my 1850KV on 8s for far so good. But the motor cost 4 times as much. My other 90mm has a 1600kv and it is only rated for 6s. You pay for quality :)

 Shaprap 180 points

I think this motor is too heavy. You better choose something like TowerPro 3015-7 1000kv with a 10X6 prop and a 40A Plush on 3 cells and get plenty of thrust. (And with 4 cells it'll be even better)
