I would guess about 12 inches in diameter and it probably weighs,
as a real wild ass guess 50 pounds ring gear and all.

Note the straight cut gears. No end thrust!

Good idea for a high power  20B Chris. Tried and true and bullet proof.
Relatively cheap too, prop shaft and all. A real bargain.

Don't know Chris. Call Aero-Engines in LA and ask Rick what they have?
