Maiden Flight of the Black Horse DH1 Chipmunk

[speedair40]

I got an os 70 in mine and flys like a dream. i havent had much trouble with torque but it did try to tip stall.

It does indeed fly very nice indeed. I think I have more torque issues because the AXI 4120 revs to maximum RPM in about a quarter of a second :-). I also need full right rudder to keep it going straight on take-off.

I have the same plane with a O.S. .91 4-stroke engine. Super flyer. A little touchy on take-offs and landings. Getting used to it.

Great, yes, you need to give a lot of right rudder, and the torque is not to be sniffed at. You can turn the plane upside down by simply opening the throttle! Mine has also got quite a nasty tip stall I need to keep an eye on!
