Got a few more flights in this weekend.. really getting the hang of it.. Flew upside down for one pass.. loops, rolls, nice low flybys.. only issue is the snow is 3-4ft deep and a pain to walk thru... SO I scored a Castle Creations PHX-45 on ebay.. so now I'm still trying to decide on the motor. I am leaning toward the Mega 16/15/3. Just run it off NiMH for starters. If I go easy on the Throttle will I flutter without extra spars? Can I add extra spars to an already completed wing (XE2)? How do you do it and where do you place them? Also I am hearing 5X5 carbon props or 6x4 APC? Any opinions?
