    This engine test 5s 4000mAh LiPo, 12x6 prop for 4 seconds allowed to run threads on the front rotor. I taped Loctite and I hope that lasts. Quality bad, a good price. Finish them at home I'm sorry.

    bought this motor to use on my great planes escapade 40 but the mounting screws are way off so I have to use another motor I bought from here so no biggy. I wanted to test this motor to see what it can do on 4S... with a apc 12X6 useing 326watts it blew everything off my work bench including the escapade and other heavy stuff... can't imagin what you would have to do to get 900watts out of it. Gonna make a spad clone of my escapade and use this motor with a 13X8 :D

    It is a good product!

    I am using a 13x6 propeller, 5s Lipo Battery plus/- 1000w.

    Works very well in a Cap 232 .40, for an acrobatic fly!

    And the price, incredible!!!

    Using this motor with 60A Turnigy Plush ESC and Turnigy Nano-Tech 25-50C 4000 4 cell. 12x6 APC prop draws around 50 amps and 750 watts.

    Motor ran great, no problems so far. Plane is a FMS P-47 1400MM with a AUW of 5lbs 6 oz.
