RE: Nitro models pusher Bobcat?
Whenever I have a difficult to land airframe without flaps nine times out of ten the cure is to put reflex ailerons on the throttle stick i.e. in a landing condition on the Tx at low throttle both ailerons go up, these act as spoilers so reducing lift and goes a long way to tamming a bounce prone landing they also add washout to the wing and so offset tip stalling, so it can also land slower, in the first instance only put about 1/4" of up on and try at hight to see how it effects the flight path and just keep on experimenting with reflex and tailplane trim till you get an approuch that you like. My Jets have them set up to over 3/4" with full flap 90 degs and 1/4" down elevator this allows landing in a very small space and at a silly low speed for a jet. Try it I am sure it will work for you.
