RE: Throttle stick position while flying!!!
With my P51 Mustang, Escapade, and now Strega 40, my practice is still that I gradually push the throttle stick and keep the plane straight with rudder and until the stick reaches to full and I feel that ground speed is full I take off and try to a good altitude until my plane is safe from any disaster. I'd certainly agree with sandal that full speed some times does make the control surfaces flutter but not all the times.
There is no definite throttle speed, but in case of higher winds and while you are flying trainer, up coming push is enough to lift your plane and you get air borne within no time and this I also experienced. I never used flaps, and we don't use slats in model planes as they have much more power and don't need slat for enough lift. This topic would be debatable but I'd like my plane to take of on WOT.
Thanks guys a lot for your great input.
