Disclaimer - Terms of Usage

 

Ohm
A unit of electrical resistance to current flow. The higher the resistance to electrical flow, the higher the ohm rating.

 

Oil
General term to describe a liquid lubricant. Also may be used in dampening systems.

 

Oil-Filled
Used to describe that the shock is filled with oil to be used as a dampening mechanism.

 

Oilite
An oil-aborbant material that can be used as bushing material.

 

One-Way Diff
A great (and simple) design, this drivetrain gives equal power to either wheel and does not rely on even traction. If when cornering, one wheel loses traction, the other takes over. This gives a superior edge, especially when powering through corners. The major side affect of these diffs, however, is that because they only supply torque in a forward motion, brakes (a backwards torque, essentially) will simply not work. This application is generally used on 4WD systems, with the fronts utilizing this diff (and therefore no front brakes) and the rear using either a bevel gear or ball diff to allow rear braking. 

 

O-Ring
A rubber ring that acts as a gasket or a vibration dampener.

 

Ounce-Inch
A unit of measurement to describe the energy needed to move one ounce of matter, one inch.

 

Outdrive
aka Diff Shaft. A slotted mechanism that accepts a dogbone drive axle on one end and a male slotted fitting on the other that is driven by the differential assembly.

 

Overgeared
The gear ratio that is set too low for it to be effective and causes excessive strain on engine or motor. Tends to have a fast top-speed, but poor accelleration.

 

Overspray
Paint that has been applied where you didn't intend it, ie, on the outside of the Lexan body shell.
