RE: CG and Control Throws
Here's a graphic that may help. You can determine the CG of pretty much any plane by using it.
Keep in mind, that ideally you want to start out by balancing at 25% of the "Mean Aerodynamic Chord" or "MAC". This graphic will show you how to get the MAC, and from there the CG.
Spend a couple minutes looking it over, and pay attention to "root" and "tip" cords.
