OK, a good looking prospect on Ebay right now.

3/4 horse 36 volt permanent magnet, 200 rpm.

Looks like you could get some nice power out of this thing.

Questions I have. I understand the tsr a little bit and see that you would have to factor that into the design. What size prop might you use???

Also, if you wanted 24 volt or 12 volt power from the rig what would you need to do???

I keep answering them in my mind but I find four for every one I think I answer.

Unfortunately that motor has a gear reduction box on the end of it.  Gear reducers don't generally do well in the long run as speed increasers, particularly those with a high gear ratio.  I'd expect that one to be at least 10X1.
