Looks pretty complicated for this farm boy.
BCCHI I bet will be a little pricey.

Cool - if it works well!
Is that an electric start, or an alternator to keep the reciever pack charged?

It's a alternator, reading the specs it supply a rectified12 volts on one output and 2 lines output 6 volts, be great to never need to charge your plane ever and be able to fit a small battery to offset the system weight. Not sure what new battery chemistry would suit a 12 volt or 6 volt regulated output safely though?, nimh cells?.

Am sure if this becomes reality all will be explained.

When was the last time you bought a car with a carb? I wonder if these OS engines start backwards 1/2 of the time?

NICE! No more full-loss electrical systems on our planes would be great.


LiFe batteries can be used on a conventional alternator system sucessfully. I have one on my motorcycle.

Life 2s would need 7.2 volts to keep them topped up nicely, the 12 volts regulated down to 7.2 volts would work I suppose.

Doesn't seem too long ago someone else said they were going to have an engine that was fuel injected. HMMM where is that engine now?

This really looks more like a UAV application.

WAHOUW! I like the 55cc one!


With 2 spark plugs and 2 electronic devices, it's seems like a full size plane engine..


So before take-off, we have to check each electronic device as on a full size plane!? Safety first!

WIth both of the plugs firing at the same time, I don't know why they went with 2 ignition modules.
