RE: Knife Edge / CofG Effect
Great glad your liking it. I have a couple planes tha KE great and then a couple that pitch to the feet. (landing gear) I mixed some elev. and rudd on one of the pitching planes and had not a clue as to what percent to go by but quickly learned that it does not take much. I guess on my Frenzy 100 size i have about 5% mix started with 15 and man that was way to much. First time i tried mixing and was a little nervous as to how it would fly regular when i used the elev. or rudd. But it if fine with just 5%. I have an addiction and an Eratix that KE great without having to mix.
Again glad your liking it and very good luck to you. 3D is an Addiction in itself lol.
