RE: Outlaw suggestions
Get a real tuned pipe or make a mousse can pipe. Fair in the engine area a little more by adding blocks to the fire wall. the fire wall is going to produce a lot of drag like you have it. Can yo sharpen the L.E. any? No wing tips? What size prop do you have there? A 8x8 APC is great. throws are a personal choice, 1/4" low rates and 1/2" high rates on elevator or aileron throw(not combined throw) is a good start. up to 45° throw on high rate rudder is good for the flat spins and snaps.
