I have also 2 questions.
1) See manual : modellirc.it/pdf/manuale710.pdf
I could not find this shim in my kit and nothing about it in my manual.
Should I buy this shim or I have latest release of S710 kit and I don't need this shim at all ?
2) In my manual in step 8.1 has sentence, something like : Please don't use cone washer from engine, but only from S710 kit, but I had no cone washer in bag 35. Is it important ? from my point engine cone washer fits ideally.

1. I don't remember exactly what the problem was with the early pinion gears, but they corrected it and the shim is no longer necessary.
2. If the cone fits on the engine crankshaft and into the flywheel properly, no problem.

Would anyone remember a good front and rear diff oil starting point for the 710? Good grip, fairly tight parking lot and running a Losi Alfa body.

Did you have gear diff in your 710?

Hey Sam, I've never run the car and just recently installed the gear diffs. From what I've read, the solid front axle takes away a lot of off-power steering so I figured I'd throw the diffs in while I had the chassis apart.

For the front diff 100,000 cst

Rear diff 30,000 cst

Thanks..I'll give it a shot.

30k front 10k rear for good grip. Good off power steering and you can still power out of the turn, good balance overall. try the same shore tires front and rear for this setup (or not very far apart like 40 front 37 rears).
