Here it is - very conventional layout -
I typically fly it with the cg at about 40% of the root - but once, when the battery pack came off -and I flew it to a normal landing - it took lots of down elevator and some aileron fussing -but it still flew.
The drawing is exactly to scale -so anyone can pick the cg which makes them comfortable - anywhere from th LE back to 40% is flyable for most people -but - you can go back further
By the way -I flew a heavy pig of a scale P51 yesterday -and the cg on that turkey was critical -
Read the prior post on eliminating the stab - and flying with flapperons only -
This is not only possible but done many times and kits were on the market .
Glad to see this guy is thinking!
