Helicopter Head speed control menu
There is a sub menu in the turbine limits menu for altering the gear ratio of the
helicopter so as to set the head speed. Access it by entering the turbine limits
menu as before, then press limits and + simultaneously and release.

Ratio Turb -> Rot
9.73
Main gear to motor ratio. Adjust by pr/- keys
while holding down change value. Set this value for
your helicopter
Ratio Tail-> Rot
4.53
Main gear to tail rotor ratio. Adjust by pr/-
keys while holding change value key down. Set this
value for your helicopter
Once the gear ratio is set press menu key to return to turbine limits menu. Scroll
through with + key until you reach
maximum rpm. Set this at 165,000. The governor will
control the engine rpm but if you load the rotor head up the turbine may need to reach
this rpm.
Press the + key to scroll through until you reach ShaftHiR1:55,000 or some other
number. The 55,000 is the rpm of the secondary turbine and will be reduced by the
gearbox. Below that you will see ROT=1650 or some other number and Tail = 7422 or
some other number. This is the head speed and tail rotor speed in the computer at the
moment. To change the head speed to the desired value, press and hold the change
value and press the + or – keys. This will change the ShaftHiR1 value which will in turn
alter the ROT value. Set the ShaftHiR1 value so that the ROT value equals the head
speed you want. If you only want a single head speed setup then the AUX connection is
not used.
The V5 ECU has a 3 speed option for the head speed and this requires the addition of a
connection to the AUX lead on the ECU which needs to be connected to a 3 position
