Re: Dont know where to put this, please read. thanks.
I made a nice little 1/10 scale 4x4 truck that is powered by a .26 four-stroke engine that runs very well. Modelman is right about the heat but, it is fairly easy to reduce the heat with an electric fan. My little truck has a belt driven fan and it keeps it cool fine even at low speeds. The biggest downfall with a nitro engine is the oily mess though. I would not want a nitro engine in a scale rig too messy for me.
A nice compromise might be an os 26 four stroke converted to gasoline with a powerful electric fan for cooling. The stock tamiya can motor has about the same power as a .15 2 strike nitro engine and the .26 gasoline four stroke would be more than enough power. You could probably even retard the timing a lot and run it at very low rpms so that it sounds nice. You would just have to make a very heavy brass flywheel to keep it running smoothly. You would also have to make custom clutch shoes full of weight to engage at very low engine rpm's.
It would be a lot of work but, it would be cool!
