Hmmmm..

Looks like I misread the original post. I thought he was looking just for a giant trainer....

I don't know of any gas that would work in this plane. Mine had a 90 Magnum fourstroker and I still had to add weight in the nose.

I would be afraid a gasser would shake this thing apart unless you pinned the firewall and or glassed it. PLus, you are correct it is just way to light.

Sory bout that!
