Ok, last night I did a rough balance check. I have all the servos in and hooked up, except for the throttle servo control rod. I dropped the reciever and standard battery in the fuse right under the CG, where the pilot would sit. Mounted up the wings with all hardware minus the struts (which are basically right on CG).

Installed the engine and muffler, MAS prop and spinner, and sat the cowling on the engine as best I could. Also put the empty tank in place.

I think the only thing missing is the throttle pushrod, struts and... oh the cover under the landing gear (which is very light and under the CG). And the electrical switch.

Balance was basically bang on. Just a *touch* nose heavy I think. I bet with the battery mounted under the servo tray (lots of room) it will come out perfect. No lead needed at all.

I'm not surprised really, since everything else is designed for this engine (17.1oz w/muffler BTW), and the tail is built pretty light. The fuse has lighteing holes cut in the tail area, and the stabilizers are build up, not solid.

My H9 Cub was very tail heavy. I will probably refinish it eventually, and drill lightening holes in the stab surfaces.

The plane was $185 IIRC, from AeroTec Hobbies in Ohio, who also gets props for prompt shipping.
