First you must take off that whiney little .25 that is supposed to be on the front of these and bolt on some real power. Y.S. 45 works real well, heh,heh.

Take out the sliding servo box and install 2 servos side by side for elevons. set your radio up for these.

I have my CG set at 1 3/4" behind leading edge.

Control throws are at 7/16".

I have expo set up at -70%.

One word of caution with this setup: Dont try to pull a tight loop with this at full throttle, the little buggers tend to go into nasty snap. If your high enough though, it looks pretty wild.
