I have tried almost everything to get my plane into a spin. I will have to try what you have said. I think my CG is on or slightly behind the CG mentioned on the instructions. I think I managed to do 1 spin once, but it pulled itself out. Just before it did the spin, I had full left/right rudder (I can't remember which) and full up elevator. The plane was doing really cool loops. The were half the size as usual and I was at half throttle the whole time. It was cool, but a spin would be cooler!
