One things for sure, a 32oz Speed 400 is not going to do it for me.
Yep no kidding....200-250w should do very nicely. I agree on the outrunner but the fit may be an issue. I was almost wondering of you could just chop the nose off (at the right length for you particular motor) and then stick a ply firewall glued directly the the glass fuse.
The shaft still needs to poke out in the right plane though.
