Already been said, but I just read this - control throws 30 degrees? Egads, it's a half-A! Save that for later. Get it flying smoothly on low throws - if it won't do that it sure isn't ready to fly with 3D throws. Small bipes have low moments of inertia and they will do terrible things to you on slow launches with jumpy controls (guess how I know). And don't be afraid to keep the CG forward at first.
