Specifications

Brushless, usually in the context of brushless motors.

Boom Strike

A type of helicopter crash where the main rotor blade hits the tailboom. This may dent/

bend the tail boom and damage the main rotor blades. This is a frequent mistake made by

beginners.

Brain Fade

A mental lapse where the person flying the heli, suddenly forgets which way to move the

controls, or which control to move at all.

Buddy Box

Two similar transmitters that are wired together with a "trainer cord" or buddy-lead This is

most useful when learning to fly, it is the same as having dual controls. The instructor can

take over control at any time by using the "trainer switch" on his transmitter.

C-rate (1C, 2C, etc. charging & discharging rate)

This refers to a charging or discharging rate in terms of the capacity of the battery pack.

For example, a 2C rate for a 2400 maH battery pack would be 4800 ma or 4.8 amperes. A

1/10 C rate for a 2400 maH battery pack would be 240 milliamperes.

CA Glue

Cyanoacrylate A form of glue, commonly called "super glue" often used in model building.

You should treat with extreme caution: always have debonding agent close by, in case

your components or parts of your body become bonded in an unanticipated way. Avoid

breathing the fumes, as they are toxic.

Collective Pitch Compensator

The assembly with two seesaw arms directly above the swashplate

CCPM

Cyclic/Collective Pitch Mixing. A type of control system where the swashplate controls both

main blade pitch and flybar pitch. The swashplate relative tilt controls the pitch of the flybar

as the main rotor rotates, and the absolute height of the swashplate controls the pitch of

the main rotor blades.
