Lapped -- See getting lapped
Lean-- A condition referring to engines where the engine
is not getting enough fuel. While running lean can help performance and fuel economy,
you run the risk of running the engine too hot and blowing the engine! If your engine
runs for a few minutes and shuts off suddenly, it's probably running too lean.
Lithium Polymer battery (LiPo) -- Lithium Polymer batteries are used in many electronic
devices. Cell Phone, Laptops, PDA's, Hearing Aids just to name a few. Most, if not
all, lithium polymer batteries are not designed for RC use, we use them in different
applications than they were designed for. They are similar to Lithium Ion batteries
in that they each have a nominal voltage of 3.6 volts, but dissimilar in that they
do not have a hard metal casing but rather a flexible material encloses the chemicals
inside. The "normal" lithium polymer batteries are thin rectangle shapes with two
tabs on the top one positive one negative. The reason we use Lithium cells is that
they are significantly lighter than comparable NiCad or NiMH batteries, which makes
our cars go longer and faster.
Locknut-- A type of nut that features a nylon insert that helps to grab the threads
of a shaft or bolt, helping prevent the nut from loosening. Commonly used on axles
and other critical areas of Rc cars and trucks.
Loose-- See Oversteer
