Expert Parameters for the Tailrotor
| Input Settings | Min | Max |
|---|---|---|
| Expo | 0% | 100% |
| Tail Stick Deadband | 0 | 30 |
| Acceleration | 1 (slow) | 100 (fast) |
| Collective Zero | -100% | 100% |
Expo
Expo setting for the tail input. Expo reduces the servo throw around the stick center and creates a softer stick feel. The full throw will be about the same as without expo setting. Usually tail expo is set at about 50 to get a common feel.
Tail Stick Deadband
Defines a range around stick center position where the stick input will be ignored. Nedded for adjustment to the TX potis. If values >15 are needed to get proper working system, this will be a hint for defective TX potis.
Acceleration
Sets the rate of acceleration (or deceleration) of the tail rotor. The weaker the tail (low rpm, short tail blades), the lower this parameter has to be set. Sensible values for pod-n-boom 30 ... 60, for scale ships 25 ... 40.
Collective Zero
Reads the zero collective position from your TX. Set TX stick to zero collective and click onto the button.
| Torque Compensation | Min | Max |
|---|---|---|
| Collective Torque Comp. | 0% | 100% |
| Cyclic Torque Comp | 0% | 100% |
Collective Torque Comp
Static torque compensation (revo-mix) for collective. Works from 0 deg. up to positive and down to negative collective. Fine adjustmend can be done by vertical climbouts.
Cyclic Torque Comp
Static torque compensation for aileron and elevator. Fine adjustment can be done by flying flips.
| Control Loop | Min | Max |
|---|---|---|
| Proportional | 0% | 120% |
| Integral | 0% | 120% |
| I discharge | 0% | 120% |
| Differential | 0% | 120% |
Proportional
Proportional gain (rate gain) part of the tail control loop
Integral
Integrator (heading hold/avcs) gain part of the control loop
I discharge
Intensity for dischargement of the integrator (decay). 0=off, VBar tail.
Differential
Differential Gain. This type of gain can be used to make the tail better on small helis and slow servos. It amplifies the change rate of the rate. So it is very quick in reaction, but can lead to quick oszillations on fast servos or big helis. So its useful on minihelis only.
| Stop Control | Min | Max |
|---|---|---|
| Optimizer (auto learn) | Off | On |
| Tail A | 0% | 120% |
| Tail B | 0% | 120% |
Optimizer
The Optimizer is estimating the normal control behaviour of the tail mechanics. This enables the algorithm to know how to design the best possible reaction. The optimizer is separate for the both tail directions. If the Optimizer is activated, it will try to find out the best values for A and B during normal flight. Its important to have a good trimflight before using the automatic optimizer.

Resets all tail values to a safe starting point.
