Hello,

I'm 95% finished with my extra 300S build and am having difficulty with the CG. I built it per the plans and later decided on which engine to use. I went with the biggest motor, OS FS-120S III which is closest to the firewall as it can get without significant modification. The battery is located by the trailing edge of the wing. I need to put 3.25oz's of lead on the tail to balance the CG which to seems like a lot of added weight. Not sure what else I can do. Any ideas. This is with an empty tank.
