DLG Taranis setup

For some it is a huge task to program your Taranis radio. A DLG has some specific features that can be tricky so the best option is to search for at RCgroups for a suitable guide. Didn’t take long to find a specific program for my 3 channel DLG, 2 ailerons and elevator. Now you think 3 channels cannot be that hard – you are correct unless you count in all flaps, breaks and mixes for different flightmodes – all depending on flight conditions.

Behrens, the author of the post linked above made it easy for us. A step by step guide with lots of features.

I choose to share his post in a big quote:

Taranis Setup for Rudderless DLG

Introduction
This is a template model designed to easily setup a DLG model and have a nice set of features readily available. You may copy, modify or just seek inspiration as you please. Any model in Taranis is likely to undergo several improvements. I’d be happy to hear your suggestions.

It’s assumed that SF has been swapped by a spring loaded switch (Could be SH – no soldering needed).

I take no responsibility for damages caused by using this model!

Features
Servo Setup Mode – An easy way to bypass all mixes and just get the servo limits/centering/inversion set up correctly.
Flight modes (Launch, Speed, Cruise, Thermal) – In each mode you can adjust the flaperon and elevator independently. No need to play around in the mixes menu – use trim buttons instead!
Alarms – Get a warning if you are about to launch and everything isn’t ready
Countdown – A simple 10:03 working time countdown
Stopwatch – Strangely enough the most complex part of this model
Differentiation – Adjust during flight
Snapflap and Flap Compensation – for a more smooth flight

Setup
1) Receiver Binding and servo connection
Bind your receiver and connect the servos like this:
CH1: Left Aileron
CH2: Elevator
CH3: Right Aileron

2) Servo Setup Mode
When you run the model it defaults the mode to Servo Setup Mode. All mixes and stick inputs are disabled. All servos are controlled by SB. Default limits are -30, 0, 30. A very conservative starting point that will not cause binding unless your mechanical setup is skewed.

Move SB to Up position. All control surfaces should move up. Enter the radio’s “SERVOS” menu and adjust the Invert settings as needed.

Now for each channel, adjust Upper and lower limits in the “SERVOS” Menu (move SB to down position for lower limits).

When done, set SB to center position and adjust the neutral position to no throw.

Once this is done we need to leave Servo Setup Mode. This is done in “GLOBAL VARIABLES” menu. Locate “GV5 Servo”. For FM0 change value from 1 to 0. At this point the sticks start to control the servos.

3) Flight Modes
As mentioned there are 4 flight modes. In each mode you can control the flaperon effect with the Throttle Trim button. You can also set elevator trim for each mode using elevator trim button.

To enter the different flight modes:
Launch: Pull SF. When entering Launch mode all other settings (Brake and other flight modes settings) are canceled. No need to worry about your settings when launching. Launch is associated with the stopwatch. Press SF a few times and you will see how it works. Simple and efficient.

Speed, Cruise and Thermal: Selected by SB when not in launch mode. Again, use throttle trim and elevator trim.

4) Other settings in flight
Your differentiation is a global setting which can be adjusted by rudder trim. Both positive and negative values can be applied

Aileron trim is also a global setting. Guess which button to use.

5) Advanced settings
Snapflap and Flap Compensation can be adjusted in the “MIXER” menu (CH15 line 3 and CH11 line 2).

Minimum battery voltage during launch is set to prevent that you throw your model before turning on receiver power.

It requires telemetry and voltage sensor (often built-in to FrSky receivers). The voltage is se in the “CUSTOM SWITCHES” menu on CS7.

Dual Rate and Expo is set in the “STICKS” menu as usual.

You will notice one of two sounds when launching. One is an indication that everything is fine. The other indicates that something is wrong. It can be:
a) Brake is on. It gets canceled by Launch mode. But you should remove brake before leaving Launch Mode.
b) Flight mode is Thermal. Similar to a)
c) We are not receiving A1 receiver voltage signal. Your receiver may be turned off.

I have an altimeter connected to my models. Moving SE will read out your altitude. Make sure to disconnect altimeter during competition.

Enjoy!

Follow the steps carefully and aim for throws specific to your DLG and you have a good start. I had to go back several times to adjust throws.

I think my setup is ready for competition but that is not my goal, I fly DLG for fun and relaxation.

    Hello,

    I can’t find any contact info in the site so forgive me for using the comment section. I’m Algen, I work with engineering website EEWeb and would love to have your website featured as a site of the day on EEWeb. Is this of interest to you?

    Hope to hear from you soon.

    Sincerely,

    Hi!

    I do not fly as much as I used to do…
