1. 20/78 is probably a starting point for your 9.5.
2. brushless is almost maintenance free. i think u can apply a drop of lubricant on the motor oil every few months. that's is all that's required.
3. setting clutch/gear - below tip is from Casper (kyosho usa team driver):
" Setting the slipper/ diff
With the gear cover off and the tires on the car, hold the right tire and the spur gear in your right hand. Then turn the left tire. Look at the slipper nut. If the left tire moves and the slipper nut doesn't your diff is set looser then your slipper. Back off the slipper and or tighten the diff. Repeat this process until the slipper nut turns. Especially with a brand new diff check the for the first couple runs. Once the slipper springs sets future rebuilds should hold a good setting from the get go.
Now that you have protected the diff with the slipper, you need to make sure the slipper is not too loose.
With a fresh battery in the car turn it on. Holding the back two wheels firmly to the table, punch full throttle on the radio. If the slipper is set right the front tires will just come off the table and come back down. Adjust the slipper until this happens. If you tighten the slipper make sure you check to make sure the slipper still give before the diff!!!!!!!
After all that you should be ready to rock and roll. As a starting point on the slipper I run the slipper nut about flush with the end of the top shaft.
It sounds more complicated then it really is. If you always make sure your slipper gives before the diff slips the diff should last a good long time!
