I put this motor in an 18" rc jet boat that i have. I run it on 3 cells. The motor gives good speed and acceleration with a 3 cell lipo. I use a water cooling mount that i got here at Hobbyking, this keeps the motor cool. A nice little motor.

Excellent moteur monte avec ESC Hobbyking SS Series 15-18A ESC en remplacement d'un moteur charbon SPEED400 avec reducteur sur un avion RAMBLER EP400.Le moteur se monte "pil-poil" en lieu et place du SPEED400 ( meme diametre d'arbre et entraxe de fixation pour le reducteur ) , il est un peu plus petit et moins lourd.Au niveau performance , il est equivalent ( voir mieux ) que le SPEED400 et consomme un peu moins.En bref,que du bon pour remplacer vos vieux moteurs charbon , je recommande -)

Very nice little motor. i use it on an old Robbe Hunter 400 pusher jet with an 5,7x3 APC. On 3S 1800 Flightmax (20C), I have around 26000 rpm for 17 amps. Runs a bit hot, will try a 5x3 soon.

Very good product.

Hello. I've bought this motor, it runs on 3s 1250 rhino li-po and Tower Pro 30A ESC in my Easy Star. It have 600g. thrust, unlimited vertical on full throttle. It runs hot, but not too hot.



Thanks for Hobbycity
