C G Funtana 90s

       Remove this ad - become a site supporter!
Ok so I am converting a Funtana 90s to an Electric I originally bought this plane From Colyn(hope he reads this and remembers) The CG in the book reads 7 1/8" from leading edge at fuse. Now Colyn had written on the front of the manual that its maiden it was set at 6 1/8" Plane has always flown well at this cg. A friend I fly with commented on why was the battery pack way up front,my answer was to balance it at the cg hand written on the front. I set the CG at recommended CG and plane flew very bad well almost didn't manage to land it So I am asking the opinion of those that have one what is the cg for sport flying to mild 3d. I need this so I can configure where to have the battery placement in the plane. One thing about going electric it will eliminate the CG point from changing as fuel is depleated.
Thanks in advance Mike

Handle every stressful situation like a dog.

If you can't eat it or hump it.

Pee on it and walk away.

Re: C G Funtana 90s

Hi Mike,

I flew my F90S a couple years back with OS1.60, pumped (tank behind the spar). From memory I think I remember flying it for 3D flights at 6 3/4", which was still a bit tail heavy, as it ballooned just a tad on approach to land, but I learned to fly it out.

RCU F90S thread is very long but if you read enough posts, you can get a good idea of what everyone else is flying it at too.
