Moved the servo tray forward, pushed the battery pack up to the firewall and still needed to add a lot of weight. Can't find the plans but recall the CG was about 1' - 1 1/2" from the LE. Spoke with another Club member and decided to add a larger engine, OS 61 FS. Well, it looked like a Blown Hemi in a VW Beetle. So, I'm going to try extending the engine mount approximately 1/2" using basswood strips attached to the firewall and stick with the OS 46. There's still enough room in the cowl to move it forward.
Thanks everyone for the feedback. This has got me stumped!
