I once saw a lightened CG Extra fly at a regional meet and it was quite impressive. The builder had ditched the ply sides for balsa and built airfoiled tail surfaces( among other mods). The plane was really awesome with a YS 120. Im just about ready to start on my CG Extra and was wondering if anyone had any tips on keeping the weight down (or other performance mods). I already plan on installing a carbon fiber landing gear and fiberglass cowl. I fly some mild 3D, more into pattern type, rolling circle, knife edge etc. But would love to be able to perform knife edge loops, torque roll well, etc.

If I could build it light enough, maybe my Saito 100 would give it unlimited vertical? On another subject, anybody know what weight the Saito 100 will pull straight up?

Any advice from the pros would be appreciated.

Thanks in advance.
