tkg,

"for guys in the pits too". I hate those low-level circles too.

captinjohn,

It looks like you made several changes to your Ryobi:
1. Glow plug/adapter
2. Removed flywheel
3. New mount
4. New muffler
5. New prop shaft.
6. Other?

I would guess that your Ryobi weighs somewhere between 3.5 to 4.0 lb. without prop or spinner? Do you have an aircraft for it yet?

Thanks,

Bruce
