F3F setup v.4.0 with quicker config

Version 4.0 of F3F setup for Taranis is now available. Enhancements are aimed at getting your 6-servo F3F ship into the air as quickly as possible. So if you want the mixing without the fiddling, this is the version for you!

[Update 20 October 2016: version 4.1 is imminent, featuring a new Pump mode.]

Quicker calibration

Previous versions of F3F Setup required around 45 minutes to configure a model from scratch. While this is pretty good for a full-fat setup, I felt there was some scope to speed up the process especially with regard to servo calibration. I think this will strike a chord with owners of the X9D and X9DP, as the button-based interface on these is painfully slow (the X9E is quicker as it uses a rotary encoder).

To this end, I've dumped the Min/Max/Subtrim method of setting end points. In its place are output curves. While they have coarser adjustment increments, in practice I've not found this to be an issue and they're so much quicker to adjust. As a bonus you get a very useful live graph.

Another benefit of curves is that they can be copy/pasted between setups.

Quicker mixer setup

Previous versions had several settings buried in the Mixers menu. Most of these have now been moved to the user friendly 'GVAR' screen. Also, flap travel and neutral are now independent adjustments.

A couple of settings remain in the Mixers menu, however these do not require routine adjustment.

Extended calibration modes

The special 'CAL' mode (for servo calibration) has been expanded, with three sub-modes selectable via a switch:

 (a) calibrate servo centres and end-points (as before)
 (b) calibrate end-points for ailerons with constrained downward movement (new)
 (c) calibrate flap neutral (new)

Quicker flap tracking adjustment

As before, the right flap is calibrated using a 5-point curve. In the new version, stick position is no longer critical when calibrating each point, as the stick response is stepped. Precise tracking can now be achieved in just a couple of minutes.

Improved snapflap expo

As before, snapflap volume and expo are both adjustable in flight. The new version expands the range of expo adjustment to include both positive and negative values.

For advanced pilots, it's worth mentioning that if you install this Lua script, then a spare control can be used to adjust deadband (for my Needle 115V I have all three snapflap adjustments - volume, expo and deadband).

Improved documentation

The documentation has been extensively re-written for a faster workflow.

Change log

See the full list of changes here.

To upgrade, or not to upgrade?

F3F Setup version 4 is recommended for your new setups. OpenTx 2.1.8 or later will be required. If you're still on 2.0, then perhaps now is a good the time to flash to 2.1. To see if your existing F3F setups are compatible with 2.1, see version history.


F3F Setup version 4 can be downloaded from OpenTx Clinic. As always, feedback and suggestions are welcome, please feel free to drop me an email or add a comment.

Finally several competition pilots in the UK F3F league and abroad have been using this setup. Thanks to all who've provided feedback and I hope you enjoy the latest version!

Hello Mike, First I want to thank you for the hard work putting a great program together. I currently have the 3.1 v and love the performance I can squeeze out of my F3F ship. I have a question, or more like a request. I can't seem to figure out how to configure a single flap\ two Ail plane with your program. Do you have any suggestions or can you whip up a modified single flap version?
I can email you my Taranis model if you want to take it.

Best Regards,

Hi Orlando, no modifications are required for single-flap/2-ail. For your single flap, use the Left Flap channel (CH4). When following the Setup Guide, ignore references to CH3 and leave Aileron-to-Flap mix at zero in all flight modes. All the adjustments will work as with the standard setup.
