1/8 scale buggy conversion - help please!

[padailey]

Ok I hit a couple snags... first I need to rethink the placement of everything. I'm just a little short on space with my original plan. I'll get that figured out. Then my center diff is binding up pretty bad. Need to get to the LHS and get another gasket.

Then the problem I don't know what to do with. My intention was to get a Wanderer 9XL but when I ordered I didn't specify that so I have a Feigao 9XL. Don't really care just stating it so you know what I have. I hooked it up to my MM outside the car. So its 6V receiver pack, spektrum receiver, servo, MM, 9XL, (2) 7.2 IB 3800's in series.....once through the initial setup I start to run the motor. I don't know what cogging feels like but the initial tugs on the throttle there is a definite stutter in the motor (every time from neutral) . This is under no load on the motor. This can't be right can it? Is there something in the MM setup that could be causing this?
