Re: Pee Wee geared prop drive
Bernie,
Interesting adapter, but appears to be only suitable for later model Pee Wee engines with non-tapered crank case nose?
Possibly a FF adapter for larger diameter propellors?
Any more details on the enclosed diagram?

Re: Pee Wee geared prop drive
In paid $102 and change for one. It came with a throttled pee wee. One sold on eBay within the last year that was NIP. Don’t remember what it went for and it dropped off my watch list.

Re: Pee Wee geared prop drive
Seen these used in .020 cargo event ( free flight cargo event ) . Some of the planes could lift 30 to 40 ounces swinging the larger prop with the gear unit .

Re: Pee Wee geared prop drive
Thanks everyone and so much for stating that I had never seen one before; when I participated in a like thread 8 years ago. Memory
Re: Pee Wee geared prop drive
I vaguely remember a review of the unit in some model magazine back in the seventies. They made claims along the lines that it could swing an 8-3 prop at 7.5 K and could be made to fly .09 to .15 trainer R/C models that were built lightly.
