Jeff, post a few photos of your FG40 installation, it would be interesting to see what you did. I have the FG36 installed in my H9 Spitfire and it's an awesome combination, it looks and sounds great, I changed the CG to 130mm and it flies much better at 130mm than the CG that is called for in the assembly manual.
