ORIGINAL: ripper-911
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
It's tail heavy. With tail heavy, you trim in down elevator to keep the tail up and the nose down. Roll inverted and the down trim now becomes up trim, plus being tail heavy!
