AJ, Donnyman, et al,
The plans shown above in the thread can be purchased from AMA ($13 + $7 S&H) and are full scale large layout drawings. It shows all the wood pieces ....etc...and their sizing. It shows "Designed by Matt Konia" and "Drawn by Tom Dixon 11/89". It is the "Super Ringmaster", also referred to as "Nostalgia Stunt". "29 or 35 Engine".
I hope to get off the ground with a K&B 19 for some gentle low altitude flight...but if this fails, will get the other engines. My aluminum mount will be "shiftable" so any of the three engines will mount.
