1) Is there a quick trick to get the center diff out? It appears the rear diff engagement to the coupler is just a bit too long to slide the coupler off to free the center diff.

2) Seems my center diff is leaking thru the screw holes on the rear or from the rear shaft. I took all the precautions during the build to prevent shaft leak though. I'm using 15K. Other than making sure to use the black grease well, is there another way to prevent shaft leak? If its from the screw holes, I'll put the screw and treat the threads with Vibratite. EDIT: The screw holes go all the way thru the diff case/cup, but the screws are relatively short. Seems that the unused volume of the holes were full of fluid. I pulled the center diff, blew out the holes, wiped it down, reinstall, ran it again, and there was no mess.

3) I got a good bit of dust from the pinion eating at the spur. The mesh is good tho. I have four other Mod1 vehicles and never had this issue without it being do to a loose motor. Do Tekno gears go thru a break-in?

4) I see a few guys are limiting the current to their motors. Now I see why. I assume they all have RX8s. Is there an equivalent setting on a Viper VTX8. I just got it so I'm not too familiar with it yet. I know it doesn't have a feature called "Motor current". EDIT: I found it. It's called "Forward Power" with settings between 50-100%. I haven't fooled with it yet, but that seems to be it.
