Engine Brain Teaser
 

Anyone have recommendations for a radial engine that will fit all three of the following:

Top Flite Stinson Reliant
Top Flite GS P-47
Unionville Hobby DeHavilland Beaver (96" wingspan)

**Bonus points if it will also fit a Glen Torrence Hanriot**

My wife has offered to buy me an engine for Christmas and I'm just frugal and ornery enough to swap one engine around. At least for a while. I've got these kits on deck.

Any opinions?
