It also had a black capicitor soldered inline on the leads. All that seemed wierd, so I soldered new deans wires to everything, but I was wondering what the capacitor and funny wiring was for?
I hope that makes sense. Also, does anyone have any good recommendations for an asphalt setup. There is a local track at hobbytown that I would like to get into racing at.
Lastly, I was wondering where I should order bearings from for the rc12l4. One of my front wheels has alot of wobble and a couple of my diff bearings are shot.
General setup for L4 on asphalt:
Pink rear tires, purple fronts.
Standard (0.020") front springs.
10degree caster blocks on the front end, one white shimm on both sides.
Toe at neutral (no toe-in or toe-out)
Camber set to have the front tires wear flat.
Use the tin (0.063") Tbar mounted with only the two outer screws on the rear pod of the car.
Use 20wt oil in the centershock and the stock green spring.
Ride height: front 4mm, rear 4.5mm. Make sure that when ready to run (with batteries and ellectronics) the rear pod is "on the same plane" as the front of the chassis. In other words: not sagging or jacked up. Adjust center shock spring tension till you get this right.
Very important: swap left and right tires every run, so they remain the same size.
For more specific setup advise, ask what the fast guys at your track run!
