Learning the RC terms: Definitions of the day!
Here we go again, the RC terms for today (or this week?) =)
Articulation: The ability of an axle to move in varying vertical directions (left wheel up, right wheel down or vice versa) relative to the chassis. It is a measure of the ease in which wheels stay in contact with the ground on an uneven surface.
BDC: Stands for Bottom Dead Center and refers to the piston’s position at the very bottom of it’s stroke. This is where you want it to be when the engine starts to cool down.
Bellcrank: Steering mechanism used in most RC vehicles that consists of two posts joined by a link. Each connects to a left or right steering knuckle with a turnbuckle with one post connected to the steering servo.
Big Block: Refers to engines that are .21 size or larger and .15 size engines that use the engine case of a .21.
Bleeding: It is necessary to remove all of the air and any excess oil when building or rebuilding shock absorbers. This is know as bleeding the shocks.
Blue Groove: This term refers to dirt tracks that have been smoothed out and packed down along the optimum racing line over time. A bluish tint results from tire wear.
Bushing: A metal, and sometimes nylon, “donut” that supports a rotating shaft (like an axle). Most metal bushing are made out of something like bronze oilite, a metal that is permanently lubricated.
Thats all for today! Keep checking back for more of the latest “terms” in the RC world!
