I'll mess with it one night this week and get the damn thing off.

I may just go back to a normal 1900 T8 motor on the big outdoor tracks for the summer and save the HD for indoor this fall winter I'm sure it will work no problem on the smaller tracks and lower gearing, but I'm thinking its just not quite enough motor to handle the big tracks and taller gearing.
