my manual say's CG is 136mm or 5 5/16 from leading edge at center of the wing. this yo yo effect happens just after take off but as the plane gains speed it even's out but still the elevator is very sensitive. I should say here that my P47 is the ESM Frank Tiano Signature series the one seen on the link provided
