Has anybody ever tried to
"rewire" that series field coil so that the motor runs best in the normal
reverse direction? If I use two E15 motors in my ET Grasshopper
conversion, one of them is going to be running CW and the other CCW to go
forward. Got any suggestions?

(power). It would be nice to have 'variable power' - using toggle
switches instead of a cam - so you could choose how far to throw the

Why not breadboard the thing and temp tie it on the dashboard (good ole
Duct tape) to see what develops. I have a 20 motor here and if you find
that vari power works dcent and useful, I might consider a motor switch
on my blower just to have the added feature.
