armed and ready for operation. Skip to Step 8 if you do not
wish to make any other programming changes. To CHANGE
ANOTHER programmable feature disconnect the battery from
the ESC and return to Step B above.
L. ACTIVE RPM CONTROL: The ESC will sound four different
series of tones to indicate the four RPM control options as
shown below. To CHANGE the RPM control setting, move the
throttle stick to minimum when you hear the tones that match
the setting you wish to have. The ESC will sound a single tone
“
” to indicate the new setting was accepted. The ESC will
now be armed and ready for operation, and skip to Step 8. If
you do NOT wish to change the RPM setting do not move the
throttle stick, and after the last tones sound the ESC will sound
“
” to indicate the programming mode has finished, the ESC
is now armed, and go to Step 8.
The active RPM control function is designed for use with small
electric helicopters. Selecting the proper RPM maximum
control value will help to prevent the ESC from overpowering
the model during flight. Refer to your helicopter’s instruction
manual for a recommended maximum RPM value. Leave this
setting “OFF” for model airplanes.
RPM control off (factory default):
first range (20,000 RPM max.):
second range (50,000 RPM max.):
third range (100,000 RPM max.):
Once all connections have been made and all programming has
been set it’s a good idea to perform a range test with your radio
before attempting a flight to ensure that a good Rf link exists
between the transmitter and the airplane. With the Tx antenna
collapsed and a helper holding the airplane, apply full throttle and
operate the other flight controls while walking away from the
airplane. Full control should be maintained at a range of up to
approximately 75 to 100 feet away from the airplane. If the system
fails this range test it may be necessary to re-route the location of
the Rx and/or its antenna away from linkages or electronic
components in the airplane. Refer to the radio’s instruction
manual for further details.

minimum service fee and return shipping charges. Before sending
your ESC in for service, it is important that you review the
“Troubleshooting Guide” in this instruction sheet. The ESC may
appear to have failed when other problems exist in the system,
such as a defective Tx, Rx or servo, or incorrect
adjustments/installation.
