eHeli
Electric Helicopter - hard to figure out, isn't it?
Electronic Mixing
A control system where the radio transmitter controls the mixing between the roll/pitch ser-
vos and the main rotor pitch servo. Also called colloquially eCCPM.

EPA
EndPoint Adjustment. This is the same as ATV.

Elevator
Airplane equivalent of fore/aft cyclic The elevator is what pitches a plane forward or back,
to dive or climb.
ESC
Electronic Speed Control. Basically, the motor controller for brushed and brushless motors.
There are two basic types of ESCs: brushed motor ESCs and brushless motor ESCs.
A brushed motor ESC is basically a switching voltage regulator connected to the motor. It
outputs a variable voltage which is proportionally relative to the throttle value. A brushless
motor ESC is basically a three-phase AC motor controller. It electrically commutates the
three phases of a brushless motor at a frequency proportional to the throttle value.
ESD
Electrostatic Discharge. This usually refers to the static electricity which builds up on the
tail belt, most often on Logo 10s. Some people have reported "ball lighting" shooting away
from Logo 10s on humid days.
Exponential
A programmable nonlinear response curve associated with a particular transmitter control.
This allows either less or more sensitivity near the center of a transmitter joystick. Often
useful for beginners to allow better control of helicopter movement.
F
Failsafe
A default setting for a receiver channel to be used when the transmitter signal is lost, usu-
ally associated with PCM receivers. This is useful for airplanes to allow the model to glide
when the signal is lost, but is less useful for helicopters.
Feathering
The rolling motion of a rotor blade along its long axis which changes its angle of attack.
Feathering Shaft
The shaft which allows the blade grips to pivot to change the angle of attack (feather). A
flapping head has two feathering shafts (one for each blade) and a see-saw head has one
feathering shaft (running through the head)
