Diet for a Zenoah G26

       Remove this ad - become a site supporter!
I have just bought on RCC a G26. Looking at it, the magnito basically consists of a flywheel at the back of the mount/housing, and coil to generate the spark. I know I could easily send it for ei conversion which defeats the purpose and adds to the operating cost because that was the reason why I bought it at the first place.

I also think the magnito has its merits too, no ei module to blow (which is rarely in most cases but still), and no battery to charge, so it is a viable option.

My question is can I lighten up the flywheel? Just lathe it off a few oz each side. What's your thought on this, will it affact the running of the engine? As well, what other thing can I do to save some more weight? Thx.

btw, the intended use of the engine is for a utility plane, just start it and fly, no big expectation on out-rage thrust.

MOST time you will end up ADDING nose weight anyways!!!

Next ---this is a GUESS on my part...BUT I would think if you made the magnet smaller you would also make the charge it makes SMALLER too.

Lighten the flywheel to me you stand a BIG chance of getting it out of balance and then your in big trouble.

With my G26, I took off the large back plate and made a much lighter set of stand-offs. That will help a bit. But this was because I didn't want to have to build the firewall box any larger.

Man, I honestly wouldn't mess with the flywheel. I'm sure that if this was a feasable option, Zenoah would have done it long ago seeing lighter gas engines are more desireable. Don't mess with perfection! The Zenoah G26 is an awsome little gasser, cheep to operate and as relyable as they come!
