Chapter 17. Helicopter Power-On/Power-Off Procedure
17.1. Helicopter power-on procedure
1. First, if you are at a flying field, follow the appropriate procedures for reserving your trans-
mitter channel. Depending on the field, this procedure may be similar to placing a pin on a
frequency board.
2. Ensure your helicopter is not powered up, and carry it to the flying spot.
3. Fully extend the transmitter antenna.
4. Turn on the transmitter and wait for it to start transmitting.
5. Make sure the throttle stick is fully down.
6. Turn on the Throttle Hold switch.
7. Make sure the transmitter is transmitting, then connect helicopter battery.
If you connect the helicopter battery without a transmitter signal, the ESC may go to full
throttle which may maim you and/or nearby people.
Be sure the transmitter antenna is at least 2 ft away from the receiver antenna when you
connect the helicopter battery. This will prevent the transmitter from overloading the re-
ceiver and causing glitching.
Make sure you do not bump the helicopter or the rudder stick while connecting the battery
because this can affect the gyro initialization.
8. Wait for both the main motor ESC and the gyro to initialize. Do not touch the transmitter
sticks yet!
9. If the helicopter uses a heading hold gyro with a tail motor ESC, then hold full left rudder
until the tail motor ESC initializes. After the tail motor ESC initializes, release the rudder
stick and allow the rudder stick to return to the middle position. The tail motor may spin at
this time. This is normal.
10. Perform a radio range check.
11. Walk to where you plan to stand.
12. Ensure the throttle stick is in the zero throttle position, and turn off the throttle hold.
13. If you have not mastered all hovering orientations yet, then you should leave the transmit-
ter in normal mode and practice hovering in normal mode. This will reduce crash damage.
However, if you have mastered all hovering orientations and are ready for forward flight,
then you should fly in idle-up mode. To switch to idle-up mode:
i. Raise the throttle stick to about 1/4 throttle
ii. Switch to idle-up mode
The heli should have less than hovering pitch at this throttle position and should stay on
the ground. If the heli starts to lift off, then quickly hit throttle hold to stop the motor and fix
