I put it in a redbird hull from H&M with 2S LiFe and it go very fast. With a 2 lipo it can go more than 50 km/h !
The cooling is very effective an with a k29 the motor is cold.
I have more than 10 min of run with 2300 LiFe.
Je l'ais mis dans une coque de Redbird de H&M
avec un pack de 2s Life et il va trs vite !!
Avec un lipo je peu aller plus que 50 km/h.
Le refroidissement est efficace.
J'ai plus de 10 min d'autonomie avec un 2300 mA.

The given engine is ideally suited for boats ECO mini. Never use without water cooling. Use a propeller of 25-28 mm.

Wow, this is the most ideal motor for a nice micro boat build!

I tested this with 7.4v 1800 mah lipos and a 25 amp speed control and it rocked! super fast and consistand power.

I got 50 watts at 8.2 amps and lots of thrust.

The motor got a bit warm with the 30mm prop and 6 cells but with 27mm and 3 lipoly, it should run cooler and higher RMP at the motor shaft.

Lots of applications for this motor at this price.

The runs really smooth.

I highly recommend this motor for weight saving and very good power to weight ratio output.

I put one of these motors in my NQD jet boat with a 60A esc, I cant say enough about this little motor, it makes my little jet boat fly! even on a 8.4V nimh. I thought the 60A esc was a bit much for what im doing so i bought a turnigy 35A marine esc. I recommend this motor to anyone who has a small boat. Thanks hobbyking for the low prices.
