My rudder goes almost 90 degrees each way . It's ridiculous. The aileron throw is outraegous. The CG is aft of 5"; maybe at 5 3/8" or so. It was just beyond 5" then I lightened the front by adding the moose carbon fiber landing gear for eighteen bucks.

You sure are on target with "flits and flings itself around". That it does for sure. Neat plane

Mine is tail heavy alright. Pretty sporty.
