The mesh was still loose (small amount of backlash) So I now have all shims to the left and none on the right. The mesh is a little tight (notchy) but doesn't feel to tight. Does this sound right? we have a 4 hour endurance race on sunday and need this thing good to go.
The weird part is my sons rtr has 4 gallons on it and I have only shimmed it twice in that time (there is 2 shims on both sides I think).
You want as little backlash as possible. You can also add shims. The stock amount won't necessarily be enough to get it shimmed right. Every gear set is different, and gearboxes can also stretch out a bit over time which means more shims to get the right mesh.

i would think, as easy as possible, landing, and then planted all 4, accelerate.. would be easier on eveyrthing, r/p, outdrives, and dog bones. rev'ing the piss out of the truck, and letting it land with power to the wheels, its going to wear on every part of the drivetrain. but thats how you get around the track fast.. so its a give and take.
that 4 hour endurance race.. is it worth a DNF? you might want to consider changing that r/p if your shimmed all the way to one side.
While I agree that landing on the gas does put more stress on your drive train, sometimes it is the fast line. With a properly shimmed and setup diff this should be no problem. 4 hour endurance race would benefit from a more conservative approach though.
