Had my first issue with the car last night while practicing. The set pin for the front drive shaft managed to punch through the little plastic collar and basically stopped the drive train while going full bore down a straight away
. Dug a little hole in the chassis, but nothing major.
Fortunately, the internal satellite gears stripped which probably kept it from doing more damage. Luck would have it, the hobby shop had NT1 composite gears in stock so I bought all three sets the had just to be safe. They are a direct fit.
I have noticed that the it seems the gears are absorbing the diff oil. My diffs don't leak, but when I have checked them they are nearly empty! No oil residue within the diff housing, so I am assuming the gears are some how absorbing a lot of the oil.
