Turnigy RotoMax 50cc Size Brushless Outrunner Motor
Upgrade your 50cc size gas engine model with the Turnigy RotoMax 50cc Brushless outrunner motor. This motor will provide clean and efficient power for your large scale aircraft without the mess and hassle of nitro fuel.
When combined with a 10s Lipoly battery, 24x12/26x12" Propeller and a 180Amp ESC the RotoMax motor will supply punchy, responsive power that only an electric setup can provide.
This motor is specifically suited for carbon fiber & wooden propellers and features an IC style 4 bolt hole design. The shaft has also been tapped to suit a 4mm bolt to make fitting a spinner of your choice easy.

I got impatient so retro fitted the rotomax into my Hanger 9 260 27pcnt, the whole conversion from DLE55 to rotomax took about 2hours and consists of 2 x 6s 5000mah turnigy Lipos, 160HV speedy and the prop off the DLE which is a 23x8 carbon Mej.
Results on Eflite watt meter 4580watts @ 103 amps after 20sec

Received 2,5 month ago but only tested on 4 nov 2011 and now again.
The motor has a bearing with problems,it totally jammed 2 times:(practically you can not use this motor).
Money throw away. I think you can not find a replacement of the bearing o internet because is not usual dimension. And is very hard to dismantle this motor. I tried once but without success.
I do not want to send it back because of paying a lot of money on transport. May it is possible to find a replacement bearing i will search after i know what is the broken bearing.
Not a god quality management.
I also have a C80 6kw Turnigy motor with the same bering problem from factory. Sad for me.

Measured Data: Kv= 190; Ri=16mOhm; Io=2.3A@8V; Weight 1070gr.
Motor has 28poles and 24 tooths. Mechanical precision very good.
Winding could be better to come down with Ri to Hacker Q80-8M but at this price an excellent motor.
