Re: Any Suggestions How To Install A Twin-Cylinder Engine?
Those motors are fun, but they are large, I hade one as a kid. It is too bad they don't have anything in the photo to give you an idea of the size. You could use one of the new Zenoa model airplane engines, I have thought about it, they have them over 100cc's it would be fun to mount one like a BMW motorcycle. LOL. Have fun, Dave

My kids would not believe me that you could walk both way's up hill to school till I took them to the house I grew up in. Ya down then up, then down, then up. No snow lots of rain snowed once. I love those Maytag washers, what a noise. And the smoke. DO you think Grandma ever mixed it correct, I don't think so. Have fun, Dave
PS: This is the Zenoah GT80, its 80cc 800.oo

That Zenoah engine is more to my liking, except for the price.
Those twin engines look short enough to mount sideways(transversely).
However, they don't have clutches, flywheels or pull starters.
The actual mounting should be resolved easily enough. How do you mount the clutch and sprockets onto the airplane engine?
Would there be trouble for the engine, or excessive vibration?

If you notice the cylinders are the same ones that they use on the single engine, they just double it up. It would not need much of a flywheel and it would not be hard to mount. Starting would need to be like a Whizzer or the happy a bump start essentially. It would look cool and I suspect someone will do it. Have fun, Dave

This starter or a much bigger one.
I cant remember the engine size is very large for an rc/ airplane
Hobbico TorqMaster 90 Deluxe 12V
Use the rear wheel for a flywheel .
Maybe a gebe belt drive.
At $800.00 that is a bit pricey.
An italian moroni engine would probably work better.

During WW-2 a man used to ride past the house daily on a bike with one mounted on the luggage rack. He had a bulldog scowl and carried a buggy whip for dogs. We figured he must be the meanest man in town. KW

Cooling a Zenoah would be a problem. A fan would have to be mounted on the flywheel. Shrouding probably also. KW
