This winter I'm planning to experiment with one of those mini gas 4 strokes, Honda, Ryobi, or Stihl but not sure which one to use. I've read the post but still not sure. I have a honda gx31 in a trimmer that is a great little engine. But the Stihl looks to be more compact and lighter. Honda also has a gx50, but it's hard to get any real dimension on anyone.

I know, why waste the time, just go with a two stroke. But the reliablity and exhaust sound of a 4 stroke are just to tempting.

Once you all help me decide on the motor, I will mod one of joe boyd's belt drives to it to experiment with scale 3 or 4 adjustable blade props.

I know, sound like a pipe dream. The combo will be heavy but hopefully the torque of the 4 stroke and reduction can turn a good size prop with interesting exhaust sounds.

Thanks
