Hey all,

Having trouble getting my 90 to balance. Using a 5000 2S Rx LiPo, header tank is pretty forward yet with a half tank it's still tail heavy. Any ideas how I can bring the CG forward?

Cheers!

Part of the reason I liked the bell crank setup is it gave better CG. With that said the 90 is naturally tail heavy.......sooooo........not much for suggestions.

Yeah it was only slightly tail heavy when I had that setup, but I guess moving the servos aft and removing all those rods has made a significant difference. I literally can't move anything more forward so I'm going to have to add weights

In case anyone is wondering, I added 80g ballast to the nose. A lot, I know, but it now balances perfectly. Can't wait to fly it on sunday!
