through the skids and clamp the wood to a table on both sides. Also, make sure the tail ro-
tor is away from any objects.
3. Install a battery in your heli, then follow the ESC directions to arm the ESC. If your ESC
does not arm, then you may need to reverse or unreverse the throttle direction.
4. Give just enough throttle on your transmitter to make the head spin a little.
5. If your main rotor blades are spinning backwards, and
i. If you have a brushed motor and a brushed motor controller, then you need to swap
the two motor wires.
If you have a diode (looks like a black barrel with a grey stripe around it, and two
wires at either end of the barrel) wired to your motor, then be sure to swap this also
because the grey band should be on the positive (red) wire to the motor. The capacit-
ors (usually yellow discs with two leads) are not polarized and do not need to be
swapped.
ii. If you have a sensored or sensorless brushless motor and a sensorless brushless
motor controller, then you should swap any two of the three motor wires.
iii. If you have a sensored brushless motor and a sensored brushless motor controller,
then you should consult your motor manufacturer. This usually requires the motor to
be sent back to the factory to have the motor retimed.
13.4.4. Transmitter throttle hold setup
You should follow the transmitter manual directions to enable the throttle hold function on your
transmitter.
Throttle hold is very good because it prevents the heli from throttling up if you must work on
the heli while it's powered and something bumps the joysticks.
Note
The throttle hold mode may have its own pitch curve.
If this is the case, you will need to set this the same as your normal mode or idle-
up mode to ensure the heli does not "hop" when you hit throttle hold to spool down
the heli.
13.4.5. Transmitter throttle curve setup (FP heli only)
For a fixed pitch heli the throttle curve should be left as default - linear from 0 to 100%. It is not
necessary to check the headspeed because you are unlikely to exceed the maximum head-
speed, as the heli will take off like a rocket if the headspeed is too high.
13.4.6. Transmitter throttle curve setup (CP heli only)
Note
This step should be performed outdoors for two reasons.
