I never tried a loop, but stall turn no problem. I mostly fly it sedately, scale-like. I do aerobatics with planes built for it. Like my Pulse 25.

I Just put my Emeter on it and got 44.6 A and 643 W : 85.73 W / lb. It seems Ecalc is way off!
Even with this power one has to feed in power slowly and never jam the throttle open for take-off to...

I have the exact same plane with the Power 46 and 13x8 running from a 4200 4s pack. It has enough power. For a scale plane like this, 65W per pound is fine. Most sport planes are way over powered, in...

Hot Esc

Sorry, it was not clear on the photo that it is on a shelf above the hole.

My Esc also gets hot, but never gave any sign of distress, even when the temperature is 30 deg C or more. Throttle...

Ventilation holes

I think the holes will be blocked by the battery. I see the sattelite Rx is mounted on the only ventilation hole. Try moving it and get your servo wires tied together to make them more compact. This...

Dave

I agree, putting them in the cowl is a good idea. Their weight and safer chemistry make A123 a winner. If the weight is not enough, consider using NiXX. These short-nosed planes that had...

Thanks a lot. I will remove the stator and keep careful notes.

I'm glad it is not the motor on the German site I have to rewind! I can read German, just need a dictionary here and there.

Electra power

I replaced my Electra's 550 with a 600 with gearbox 2.8:1 swinging a 11x8 folder, on 7 cells. It is a bit heavy but flies well, at least a lot better than the 550. Been thinking of converting to AXI...

My Mirage with the AXI 2814/12 flies well, maybe too much power, but one can always throttle back! I would also be interested to do the steerable tailwheel mod.

Power for Mirage 550

The AXI 2808 could be OK, depending on the all up weight. What prop/batt will you use?
