I was glancing through the hundreds of airfoils for my next homebuilt combat plane and quite frankly I'm just not sure which one would be good. I thought about copying teamseaholms avenger until I read that CG range is really small and if your off just a touch it can be disasterous. Any of you airfoil buffs got a suggestion?
Would simply a fully symetrical foil be an overall good way to go with the spar area back say 1/3 of the way? I like the fully symetrical idea due to the fact that it's easier to cut out of the foam but I don't know where to put the spar section. I need to keep speed and turning ability high on my list of needs but overall flyability is also important for my slow thumbs. So far I've just designed this plane in my head but I just got the foam for the wings so building is just a few days away.
72" span
12" root cord
6" to 8" tip cord
straight leading edge
1 1/2" thick at root
1" thick at tip
1 1/2" ailerons
approx 28" fuse
.32 size motor
Wide CG range
Thanks
