Fixed wing 5 channel, with flaperon implementation on flight modes, two modes gyro setup with variable master gain, throttle hold, expo/dual rates with custom curve (linear part is the same for all rates, the exponential part has high-medium-low) the weight of the expo curves is adjustable using a GV on a pot. For example high rates can achieve 100-60% of maximum stick input, telemetry, voice announcements (sounds included)

5ChFEG is a fixed wing model implementing:
Channel assignment is TAER, Throttle hold on SF using the safety custom function. Flaperons with slow deployment is implemented on flight modes using SB. Percentage of flaperons is defined using GV1. Note when flaperons are deployed the mix does not allow the servo to exceed the bound limits thus roll is always on the aircraft centre axis along the fuselage. In the flaperon mix there is also some elevator up (GV2, negative value is elevator UP) to compensate for flap deployment; you need to adjust the GV elevator compensation to match your aircraft.
Expo/dual rates with custom curve (linear part is the same for all rates, the exponential part has high-medium-low) the weight of the expo curves is adjustable using GV5 assigned to a pot. GV5 can range from 100-60% so your high rates can be adjusted on the fly between 100-60% of maximum stick input.
Gyro stabilization (Hobbyking Rx3S flashed with open flight stabilizer - google is your friend), telemetry using two FBVS on the analog A1/A2 ports on a D8-XP type Rx to measure total Lipo voltage.
The CSP & CSQ activate the Knife edge mix compensation using flight modes on CH2, CH5 for aileron using GV3 as weight and curve 2 (note !curve 2 is the opposite of curve 2) & CH3 for elevator using GV4 as weight and curve 14. The CSP & CSQ are active only when SB is up (no flaps)
CH8 is my gyro channel, the SE switch defines which mode you are using (rate mode, off, hold mode), one can adjust the master gain on each mode using the S2 knob.
CH11 is a separate mix to change elevator position and quickly compensate / rebalance the a/c inflight without using trims because of fuel consumption or because you used a lighter/heavier Lipo and your C.G. has changed, or whatever reason you might have.
CH13 to CH19 are various mix where elevator input is source on a curve. The mix is triggered using custom switch CSM, CSN and currently we add CH16 and Ch19 on the two ailerons servo, so that ailerons and elevator work together. CH13 to CH16 the aileron elevator control surface move together, CH17 to CH19 the aileron elevator control surfaces move opposite of each other. I tried CH13 to CH16 in the field and it works, I can hover at much lower speeds without much elevator throw, and I can put the a/c into prop hang easier. My loops are smooth but the loop radius is surprisingly bigger. I also tried CH17 to CH19 mixing where the aileron elevator control surfaces move opposite of each other and I was told that the aircraft can take off with the nose facing the ground. I haven’t tried this mix for real yet (bad weather) but I did try it using Phoenix RC simulator and somewhat it does work.

As I said in previous version of this document I’m naming CH13 to CH19 mix the “taranausarous mix” – you head it here first…! In case of copyright infringement etc  J

In Custom functions voice announcements of Lipo voltage repeating every 10 seconds when the voltage is = than a set value. Logs start when your throttle is active (and stop when its deactivated). Logs are loated in the LOGS folder on your taranis SD card. Long press on the SH momentary switch resets the timer. There are various voice commands that are triggered with custom functions. The English language Acapela Heather voce for the Taranis is attached in to the zip file as well as additional files used in my voice commands and the model setup file.
Simply paste the sounds files into the “\Sounds\en\” folder on your Taranis.

Note due to a known software bug I also renamed the tada.wav and timer10.wav in my “\SOUNDS\en\SYSTEM\” folder to REN_tada.wav REN_timer10.wav
I believe with OpenTX 2.0 & onwards the issue will be rectified.

Note if your aircraft servo move the control surface in par to the other side it is recommended to reverse the offending servo signal in the limits tab instead of changing the mix. If the roll movement is correct based on stick input but the flaperons move up instead of down, swap servo channels on your rx (don’t forget to reverse both servo signal in the limits tab)

There is also a model setup for Phoenix RC Simulator based on the above setup

Last I also attach my excel spreadsheet that can help you to:
Calculate the channel range of a source using a set weight and offset
Calculate the weight and offset for a desired channel range
What the formulation is behind expo curves and how to create your own custom curve with a linear and an exponential part.
