Buying a Used Tamiya Rock Crawler (and What to look for)
Make a General Visual Inspection
Check the Body-Shell
If the body shell of your Rock Crawler is broken, ripped or damaged in any way, this can be easily repaired with rubber solution glue. Also, for added protection and if available for your model, fit an under guard to stop dirt and gravel entering the chassis. Drive Shafts and Turnbuckles
Examine the Drive System
The gearbox of your used Rock Crawler should be opened up to check for damaged gears and wear. If there is excessive backlash in the gearing, these should be replaced. A thin coat of grease on the gears is enough to allow smooth operation and reduce further wear. Pinions and Spur Gears
Steering Servo and Servo-Saver
Don't Forget those Bearings

Hints, Tips and Information
Dampers
Dampers, Shock Absorbers, Shocks - call them what you will, they are one of the least understood, but most important tools you have for adjusting the handling characteristics of your RC model.
So how do Dampers work?
Basically what you have is a small amount of silicone oil contained in a sealed cylinder. Through the centre of that cylinder is a metal rod, and on the end of that rod, a piston with a number of small holes in it. Pulling, or pushing the rod in and out of the cylinder, your will notice a certain amount of resistance as the oil is forced through the holes in the piston. |

My First National
When I first started in RC, way back in the late 1980s, I would turn up to the weekly club meeting, with my Tamiya Boomerang, Acoms transmitter, two sets of crystals, a couple of 7.2v batteries, a charger and a tool box with a wheel spanner and a few spares. |
