You all have good suggestions. For now we are still testing.
Duh you said your motor left grooves on the aluminum? Are you saying the end can left grooves or indentations on one side of the mount?
We haven't run into that yet but I'll be looking for that...
I dont have gear issues anymore since I now can gear 78 spur/ whatever pinion.
As for that slipper I havent seen one yet but I should go ahead and order one and see what can be done with it.
