On hk there are 3*7*3 and 3*10*4 bearings, that might fit. Which should I take?

 branden 40 points

yes but you have to watch the temperatures of the engine.make sure you have a lipo that will supply the engine and esc with enough amps.also make sure you have good gearing ratio or it will over heat.

 branden 40 points

yes its very good in the mini e revo and almost any mini rc. ive got it in a mini 8ight and the m8

If you want a good motor for the fun jet go With the ntm prop drive 28-36 3000kv 750watts witha turnrgy trust 70 amp esc. I have just upgraded from the 55 amp to the 70 and I am yet to check its air speed. On the 55 amp Setup i measured my air speed with a gps logger at 210 km per hour. Can't wait to measure the 70 amp setup. I run this on 4s 1800 and 2200 nanotech, this is not a setup for beginners

I use this motor in my jet Skyfun. Very satisfied! It flies great, maesured speed more than 180 km/hod. Battery 3s 2200mAh Nanotech 45/90C. Propeller 5x5". Static current 56 Amp, 579 Watt. It is better than my previous motor, Typhoon 2218 kV3450 with prop 4,7x4 (47 Amp, 492 Watt)

Jean this motor has too high an rpm for direct drive unless you run a very small prop. You need an outrunner or a gearbox for this motor. Cheers *)

Hi OzBlueDragon, would a 6x4 folding prop be "small" enough for this motor?

 leonardi 12 points

well, in ecalc it shows the motor overheating with a 4.1x4.1 propeller at 34A maximum. Anithing bigger by the calculation will simply melt the motor...

 OzBlueDragon 37 points

Leonardi you need to run this motor on a gearbox with maybe a 7x6 or 8x6 Slow Fly Prop. This motor is high RPM and low torque which means you will burn it out on direct drive hence the ecalc results. You could use this motor in an EDF only for direct drive. In a car set up it will be geared very low to use the rpm of the motor. Hope this helps you my friend. *)

no, this made ??for scales 1:16 to 1:18 ... but could be because it is a very powerful motor

 branden 40 points

nope good torqe but not enough for a 1 10 scale.

 Joel 97 points

outrunner would be ideal, but you could still use an inrunner as long as it mounts alright.

 Joel 97 points

yes, ive ordered one for my 1/18 stadium truck, and yes this motor is for smaller scale vehicles, not suitable for 1/10 scales etc

 biggfol 29 points

yes I have one in my 1/16 buggy, works a treat.tuns cooler than the original.

XK2858-3600KV will produce more torque and can handle bigger kit.

is this a good motor to use with HobbyKing Brushless Car ESC 45A w/ Reverse, Hobby King Programming Card for Car ESC, Turnigy nano-tech 1800mah 2S 25~50C Lipo AIRSOFT Pack plz reply masa

 esteban 4 points

i think yes, but you should gear it ccording the power is delivers

 Peter 66 points

guys, this is a 1/16 1/18 scale motor

 brandon 8 points

yes, that motor is sensorless

 Peter 66 points

this is a 1/16 1/18 scale motor. it is size 130, like an xmods motor(sort of, you get the idea)

 Peter 66 points

it is meant for small scale, it should work

 andropow 5 points

a) Yes
b) search *) 1600-2200mah
c) minimum Turnigy 18A(50A peak), beter turnigy 35A

 Aubin 16 points

I measured it at exactly 3mm. Hope it helps !

 Marc S 14 points

Auch, that's gonna take a piece of paper between it and the pinion then. I have never seen 3mm pinion's haa anyone?

 Marc S 14 points

I`ve put a childrens straw over the shaft. That made it 3.17mm.

This motor is too small for the Rustler and Stampede. This one is the same diameter of the 1/16 Mini Revo motor! You want to find a 540 can for the Rustler and Stampede, also a 35A ESC is too small for the Rustler and Stampede, go with at least 60A.

 bgo.o 5 points

This engine does not mount on the rustler and stampede at a distance because of the mounting holes being 17 mm and the diameter of the body to be 24 mm, a search engine with the body of the diameter of 36 mm and distances of the mounting holes 25 mm. It has tons in Hk.
