Concepts

The two key controls for transmitter based tuning are:

• A "tuning knob", setup on your transmitter to a convenient knob or slider and linked to an RC channel that your board receives
• An optional "selector switch" for controlling advanced features of the tune. This should be linked to a two position switch mapped to a RC channel that your board receives. A spring loaded switch (such as the trainer switch) works particularly well.

In addition to those input controls the following concepts are useful in understanding the tuning process:

• A "parameter set" is a group of related parameters that can be tuned one after the other in a single flight
• The "mid-point" is point on the tuning knobs range where it produces a PWM value half way between minimum and maximum

Setting up for tuning

To setup your vehicle for tuning you need to set the following parameters:

• TUNE_CHAN: the RC input channel associated with your chosen tuning knob
• TUNE_CHAN_MIN: the minimum PWM values produced on TUNE_CHAN
• TUNE_CHAN_MAX: the maximum PWM values produced on TUNE_CHAN
• TUNE_PARAM: the parameter or set of parameters you will be tuning
• TUNE_SELECTOR: the RC input channel associated with your chosen selector switch (optional)
• TUNE_RANGE: the scaling range which the tuning knob covers

The TUNE_PARAM parameter selects the parameter or set of parameters you will be tuning. Values of TUNE_PARAM less than 100 correspond to individual tunable parameters whereas values of 101 or higher correspond to sets of related parameters that can be tuned one after the other in a flight.

Use your ground stations parameter interface to see see the full list of tunable parameters and parameter sets available for TUNE_PARAM. For Plane most of the parameters are associated with tuning the QuadPlane VTOL motors as those are the most difficult to tune. You can also tune some fixed wing parameters, although most people find the automatic tuning with AUTOTUNE mode is the best option for fixed wing flight.

If you want to tune a set of parameters (by choosing a TUNE_PARAM value over 100) you must have a selector switch configured with the TUNE_SELECTOR parameter.

Using the tuning knob

The basic operation of the tuning knob is very simple. If the tuning knob is at the bottom of its range then the parameter being tuned is set to the initial value divided by the TUNE_RANGE. If the tuning knob is at the top of its range then the parameter being tuned will be set to the initial value multiplied by TUNE_RANGE.

So with a default value for TUNE_RANGE of 2 you will be able to change the parameter in a range from half its initial value to 2x the initial value. This is a good range for many tuning tasks.

Tuning multiple parameters

You can tune multiple parameters in one flight by setting TUNE_PARAM to one of the "tuning set" parameters. For example, if you set TUNE_PARAM to 101 then you will have 4 different stages to your tune:

• Roll: Rate D
• Roll: Rate P and Rate I
• Pitch: Rate D
• Pitch: Rate P and Rate I

notice that Roll: Rate P and Rate I is actually two parameters in one, controlling both the P gain and the I gain for roll. This follows the normal advice for MultiCopters that you should keep the P and I values equal when doing a manual tune.

When you choose a tuning set with TUNE_PARAM then you will initially be tuning the first parameter in the set. Once you have adjusted that parameter as much as you need to you can move to the next parameter in the set by holding the selector switch for more than 2 seconds. It is suggested that you count to 3 to ensure you are over 2 seconds.

Holding the selector switch for more than 2 seconds will switch you to the next parameter and will also change the tuning knob back to its "wait for mid-point" state on the new parameter. The buzzer on the board will give a loud BEEP sequence to indicate which parameter in the set you have changed to. For the first parameter in the set, you will get one loud BEEP. For the second parameter, you will get two loud BEEPs and so on.

When you have cycled through all of the parameters in the tuning set you have chosen it will wrap back around to the first parameter in the set.

Saving the tuning results

When you are happy with the tune you can save the result by holding the selector switch for more than 5 seconds. After 5 seconds the board will make a rapid bup-bip-bup-bip sound to indicate that the save is complete. If you leave the selector switch in the high position then tuning will remain disabled after the save.

Reverting the tune

If you are not happy with your tuning results or the vehicle becomes unstable you should change flight mode. Any change of flight mode will immediately revert all of the parameters you are tuning to the last saved value. However, you can prevent this reversion upon flight mode change by setting the TUNE_MODE_REVERT parameter to 0.

The tuning process

The tuning system is designed to make it easy to quickly get a reasonable manual tune on a vehicle in one flight. The most common use for this type of tuning will be in adjusting the rate roll and pitch PID gains. The tuning procedure outlined below is for that particular case.

TUNE Values

** Traditional Heli Only

These values can be either set manually or using Mission Planner

Setting with Mission Planner

Rate Roll P and Rate Pitch P will be used in the following example procedure

1. Connect your autopilot to Mission Planner
2. From parameter list, assign channel x to transmitter tuning with RCx_OPTION = 219.
3. On Mission Planner, select CONFIG>>Extended Tuning
4. Set the TUNE drop down box option to "Rate Roll/Pitch kP"
5. Set Min to 0.08, Max to 0.20 (most copters ideal gain is within this range although from a small number of copter the Max can be as high as 0.25)
6. Push the "Write Params" button
7. Turn your transmitter's CHx tuning knob to the minimum position, press the "Refresh Params" button and ensure that the Rate Roll P and Rate Pitch P values become 0.08 (or something very close)
8. Turn the CHx knob to its maximum position, press "Refresh Params" and ensure the Rate Roll P moves to 0.20
9. Move the CHx knob back to the middle
10. Arm and fly your copter in Stabilize mode adjusting the CHx knob until you get a copter that is responsive but not wobbly
11. After the flight, disconnect your LiPo battery and reconnect the autopilot to the mission planner
12. With the CHx knob in the position that gave the best performance, return to the Copter Pids screen and push the "Refresh Params" button
13. In the Rate Roll P and Rate Pitch P fields re-type the value that you see but just slightly modified so that the mission planner recognizes that it's changed and resends to the autopilot (Note: if you re-type exactly the same number as what appears in Rate Roll P it won't be updated). So for example, if the Rate Roll P appears as "0.1213" make it "0.1200"
14. Set CHx Opt back to "None" and push "Write Params"
15. Push the Disconnect button on the top right, and the Connect
16. Ensure that the Rate Roll P value is the value that you retyped in step #13
