I read your last post just now after returning from flying my Falcon at my local model field. The field is a short mown grass strip (www.larcs.com.au
) and my Falcon has no problem with it at all.
Takeoff run is about 30m at full throttle from the K80 and landings only a little more. Today I slowed to a standstill into a 10 knot headwind with full flap deployed. Nose up attitude and a gentle rate of descent. Ailerons were responsive with no tendency to drop a wing. I have forced a full stall with resulting wing drop by assuming an excessive nose up attitude, idle rpm, no flaps and plenty of recovery height. The falcon dropped a wing, I let the nose drop and applied full throttle command, it accelerated quickly and recovered to level flight just as the rpm came up. Loss of height was about 80' so a full stall on the landing approach would be fatal but I really had to abuse the model to get it into a full stall. when landing I usually lower gear and flaps (flaps are as per factory setup and lower to about 45 degrees) on downwind, throttle to idle halfway through base leg turn onto final and assume about 10 degrees of nose up. This usually gives me a gentle descent with plenty of elevator authority left for flare.
I hope this info is useful.
