Buying a Used Kyosho Optima-Mid Buggy (and What to look for)
Make a General Visual Inspection
Check the Body-Shell
If the body shell of your Kyosho Optima-Mid 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 Optima-Mid model, fit an under guard to stop dirt and gravel entering the chassis. Drive Shafts and Turnbuckles
Examine the Drive System
Drive Belts need checking at regular intervals for wear, tension and damage. If deemed necessary, adjust the tensioning pulley until the belt can be depressed in the centre by no more than around 5mm. If the belt was slack, also examine the drive pulleys for wear. The teeth should provide a well seated fit for the belt teeth and not be rounded on the corners. If the belt teeth do not fit snugly, change the pulleys as soon as possible. For top level racing it may be prudent to replace all belts and pulleys after each race meeting. Pinions and Spur Gears
Don't Neglect the Ball-Joints
Ball joints always cause problems. For top level Electric Buggy racing, the plastic ball connectors should be checked and if deemed necessary changed after every meeting. A simple thing like a loose fitting connector popping off could easily end your race, so better safe than sorry. Steering Servo and Servo-Saver
Stabilizers
If body roll on your Kyosho Optima-Mid is a problem, handling can be improved with the use of stabilizers, anti roll or sway bars, stiffer tuning springs and, or, thicker silicone oil in the dampers. 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. |
