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.
Quick update on props, thrust, amps, etc. My setup is this motor, Turnigy DLUX 160, and 12 cell with a 23x08 Xoar prop. This delivers about 36 punds of thrust at about 110 or so AMPs. Like many I need better batteries, but the motor is happy with it and the ESC is happy as long as there is airflow. (So I may be modifying the cowl to make sure we get better airflow.)
Just curious if anyone has any crazy ESC cooling ideas? (Like a water-cooled radiator for a PC processor...)
2 thumbs up!
Excelente motor, acabamento de primeira linha, vou usar em um Sbach 342/ 60cc.

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.
