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.
No where have I found out what the timing is for this engine. Does anyone know?
I have it paired with a Turnigy dlux 160A HV Brushless Speed Controller (OPTO) and a Turnigy 22x10 3D prop. 2 X 35c 5300 6cell . As I advance above half throttle the engine started to surge stopped when throttle retarded ,on landing after a 4 min maiden flight the ESC was very hot to the touch the batteries warm the engine cool.
I was asked by the guys at the field if I had set the timing? and throttle for the ESC.
Any help would be greatly appreciated.
nice build,at idle on 24v the current was 3,7Amp.not like in the hk description 1,6Amp at44v

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

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.

Tried it some minutes ago with 21x10 woodprop.
Batteries: 2x Rhino 6s1p 4900mAh 25C with more than 100 cycles.
Current: max. 120A
Voltage: 43V at full throttle
Power: 5160 Watt
Because the power will be even more with new batteries (with higher C-rate (>30C)) I will mount a
Will try it again with new batteries and a 20x10 prop.
