Default Airfield 70mm F-4 Balance point

Hello, Has anyone else flown this jet with the 150mm as shown. Flew for first time yesterday and seemed real tail heavy in flight. Thanks

Default RE: Airfield 70mm F-4 Balance point

hitmiss...I have this F4 being shipped right now from NitroPlanes and I also have a 2009 article review of Carl Rich flying the F4 at the first suggested CG at 165mm back from the wing....he said he almost lost the plane at this cg and with the 2200 4s battery pushed all the way back the 150mm CG was the best point for flying. He contacted HobbyLobby and they agreed and were going to change the manual from 165mm to 150mm back from the wing ..this was a Feb. 2009 RC Sport Flyer magazine...
