Giant EX 300 pre-flight questions???
Concerns about my 84" span scratch built Extra 300??? It weighs about 17lbs. and the wing loading is 29oz/lb (21in center chord and 12in tip chord).
I'm using an OS 1.60 FX engine and 180oz/lb servos. Since the wings are joined together do you only use the dimensions outside of the body for wing
loading calculations? I've used the full span for wing loading. If you only use the wing area outside of the body, the loading will, of course, be greater and
quite possibly just too great??? Is attention to stall speed critical with a plane of this size or, because of the large wing area, will it tend to float a bit at
slower speeds and not just "fall from the sky"? As you can tell, I'm a novice in this area of RC - I've only flown planes with up to 60" spans and never
had much trouble with stalling. I'd certainly appreciate your comments! Many thanks, Ollie Burns
