This is the page where you set up your Helicopter internal Governor settings.
*Only adjusts Heli Governor settings when the Internal Governor is activated in the previous menu- Device Mode*
SETTING UP AUTOROTATION BAILOUT
***IMPORTANT! Before setting up Autorotation Bailout please remove your pinion, or remove
both your main rotor and tail rotor blades!!!***
Before assign the bailed out switch, you have to calibrate the throttle range to a precise
throttle range.
In your transmitter, assign a switch to Bailed Out. Once assigned to a switch, adjust the Bailed
Out value so that the Throttle % on the radio correlates to 20% (20% - 29% is OK) on the
Scorpion Heli ESC value in the software. Congratulations, you have now activated Autorota-
tion Bailout mode on your Tribunus ESC.
To confirm that you have indeed setup Autorotation Bailout Mode correctly, spool up your
machine to Idle Up 1 or Idle Up 2, then switch to bailed out. Wait 1 or 2 seconds, then click
back to Idle Up. The throttle should quickly come back up to your Idle Up 1/2 Headspeed.
NOTE: If you have flipped your Bailed Out switch and activated Autorotation Bailout
and wish to have your Headspeed come up back slowly (as it should when first spooling
up), you must first go to 0% throttle first, then spool up normally.

HELICOPTER MENU
The Spool-Up process of the Tribunus ESC, when using the Scorpion Internal Governor, is split
into 2 separate adjustments. The "Soft Start Acceleration (2A)" adjusts the spool-up rate from
0-30% of Spool-Up process. The "Acceleration (2B)" adjusts the spool-up rate from 30-100% of the
Spool-Up process. This seperation of the 2 acceleration sections allows you to customize the
spool-up process to your own personal preference.
SOFT START:
2A - Soft Start Acceleration - This value adjusts the acceleration of the motor between 0-30% of
the Spool-Up process. Adjust this value so that the spool up from 0 rpm to a few hundred rpm is
as you like. You can adjust this to ensure your model does not yaw to one side due to torque, or
that your blades do not fold during the initial spool-up.
ACCELERATION:
2B - Acceleration - This value adjusts the acceleration of the motor between 30-100% of the
Spool-Up process. Adjust this value to your own personal preference. Normal pilots might like a
faster spool up here after the initial soft start acceleration, so that the spool-up process does not
take too long. While some scale or F3C pilots might like a much slower spool-up process. This
value also effects the speed at which your model will change RPM's when switching between
flight modes.
BAILOUT ACCELERATION:
2C - Bailout Acceleration - This value adjusts the acceleration of the motor when using the
autorotation bailout feature of the ESC. It's allows the user to quickly spool up his blades when
desired (for example, if an autorotation does not go as planned and the user immediately wants
his rotor to spool up quickly). A lower number will cause the main rotors to spool up faster. A
larger number will cause the main rotors to spool up slower.
GOVERNOR:
Allows the user to adjust the Governor Gain Settings. It is recommended to begin
with Default first, then change Gain settings to achieve the desired performance. “Soft” gains are
pre-set lower than Default and “Hard” gains are pre-set higher than Default.
GAINS:
Adjusts the P, I, and D Gain of the Governor.
I GAINS correction:
Allow the user to correct the I Gain performance.
Stored RPM:
Allows the user to adjust the RPM that used before.
