I have a scratch built 35% Edge 540. It is modelled after the Aeroworks Edge. I have been experimenting with CG placement and have recently moved the CG back so that it is on the leading edge of the pipe for the wings. Since I have done this I have flown it and trimmed it but once trimmed, when I roll it to the inverted position it begins to climb at a 30 to 45% angle.

No one in my club can explain this at all. Could someone please tell me why this is happening?

Thank you in advance,

Regards,

Robert
