After flying for months on a Himax motor I thought I would try an AirPower 400DH outrunner motor. Its lighter and shorter than the Himax.

After a bit of filing to suit the wider pitch of the mounting screws and fitting an 8T pinion, in it went.

I tried it out today putting 2 packs through it. it certainly has more oomph than the Himax but it knocked my flight time down a lot I thought (although I didn't actually time it). I know you don't get anything for nothing... and I was getting more zip out of it but it was also running the Li-poly's a lot hotter.

Does this motor require different settings on the CC25 ESC than for the Himax (timing for instance)?

I liked the power but didnt like the extra heat in the packs and the shorter flights.

See the justgofly.com webpages for cc25 setups. Try to check out your headspeed. I had to drop my maximum throttle curve settings to 85% in order to keep the headspeed below 2400 rpm. At 100% it was 2700-2800 rpm! This should also give you a bit more duration.

In general, outrunner motors are not quite as efficient as inrunners but they do have more grunt (torque). Be gentle on the throttle or your will strip gears!

Cheers.
