Considering adding flaps to a 64" P40 ARF .The airlerons are 25.5 inches at this time . Can anyone suggest the proper split of flap to airleron to fly safe? Also do I need flaps on a 64" plane , this is all new to me but I have read how proper use of flaps can tame a landing .
Is light ply a good material for flaps and I assume one servo per each flap.
Thanks for any and all help .
