 Vos stickers 20 points
Yes you can run it on 12s. Jorg says it's with a 23x10 but I run it with a 24x10 without problemes. The poles I can't awnser you, I think 24.

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.
