Specifications

Note
Be sure to remove the motor pinion when programming the ESC! This will ensure
the main rotor will not spin accidentally.
If you are using a programmable ESC which uses the transmitter to set the ESC options and
you have previously set a throttle curve for this model, then you may need to reset the throttle
curve to default (e.g. linear from 0 to 100%) to program the ESC otherwise the ESC may not
be able to recognize the low-middle-high stick positions.
13.4.2.1. Castle Creations ESC parameters for the MAIN motor
Cutoff Voltage: as low as possible so the heli will not fall out of the sky. If you are using lithi-
um polymer batteries, you will need to be careful not to drain the batteries beyond the re-
commended minimum voltage.
Current Limiting: insensitive
Brake: disabled - so we don't strip the main gear when the motor spools down.
Throttle Type:
For FP helis: fixed endpoint
For CP helis: If you are learning hovering (and are planning to fly in normal mode) then
you must use the fixed endpoint mode. Otherwise, if you plan to use the idle-up mode,
you should use try the low governor mode first, and if there is not enough headspeed,
try the high governor mode.
Timing Advance: depends on motor, choose standard if unknown
Cutoff: soft
Soft start:
FP helis: fast start (soft start has problems when used with FP helis on some firmware ver-
sions)
CP helis: softest start
PWM Switching Rate: for coreless (non-cogging) motors, set to the highest switching fre-
quency; for other motors, set to a lower frequency.
Note
Do NOT use autocalibrate mode. This mode only works properly if the throttle is
moved to full throttle to set the high throttle endpoint position. This cannot be
safely done on a helicopter because the helicopter will climb very rapidly.
13.4.2.2. Castle Creations ESC parameters for the TAIL motor
If you have a tail motor ESC, then it will require programming as well. You should temporarily
plug the tail motor ESC into the throttle channel on the receiver to program it.
For the Castle Creations ESCs used as the TAIL motor ESC, the following parameters should
be used:
