Taranis mixer settings, moderate complexity

These mixes are examples of how OpentX  works and what can be done, they are not meant for using as the amounts, servo direction and centering may not suit your model.
flaps and V tails need setting up carefully to avoid binding and symmetry problems. The channel numbers GVs and curves will need moving to used numbers

Try out these mixes 

Brake elevator compensation adjusted with the throttle trim

This is a configuration that uses the the throttle trim to adjust the down elevator compensation used on F3X and f5j gliders

This would work for popup brakes but would need up compensation

Another line from the elevator channel gets its weight value from Channel 13 where the value of the brakes and throttle trim are combined, use your brake arming switch for this mix

Disable the throttle trim, you don't need it

As the throttle lever is pushed forwards the value of channel 13  goes to minus 100, reverse values if you wish to pull for brakes
The amount is controlled by the curve,

The non linearity is corrected with a curve

A second line multiplies the stick value by the position of the trim lever used as an input, a large offset is used, this limits the value of the trim

Trim is off, decrease offset to increase this mix sensitivity, use extended trims,
 

The 2nd line of the elevator gets it secondary input from channel when the brakes are armed with switch SA

Fly the model put the brakes on full, adjust the throttle trim to get the desired pitch angle, note the elevator reading from the channel monitor,
when you land centre the throttle trim and adjust point 5 to give the same amount of down elevator. Use half brake and set point 3 by leaving the curve open while flying, then 2 and 4

If you use modes this trim would only be active in landing mode

Mix from Mike Shellem

Brake/elevator compensation trim on the elevator trim

When the brakes are armed the trim changes from normal elevator trim to trimming the brake compensation.

when open TX uses adjust GV with the elevator trim as a source the normal trim function is suspended

The throttle is used as a source

A curve controls it

this is multiplied by GV2 in the second mix line

Gv2 is given its value from the elevator trim

The 2nd line of the elevator gets it secondary input from channel when the brakes are armed with switch SA

The elevator trim works normally until the brake arming switch is thrown, this effects the amount of brake compensation applied

Trim your model the same as above, only set the trim with the brakes full on, use the the curve to correct mid points

This works OK on a TX but not on Companion

Variable aileron Differential, with camber and brakes

With this mix the aileron differential is increased as camber is applied, as the camber is applied the amount of down needs to be reduced, this has the effect of increasing positive yaw.

When crow braking is used, the amount of down aileron is increased to keep aileron response

The RH aileron gets its diff value from GV1, Left aileron needs minus GV1

GV1 gets its value from channel 14

Channel 14 is given a value of 50, adjust to suit your model

The left slider that applies camber increases the value of Channel 14 when the camber switch is on

This mix first reduces then reverses value of channel 14 as the brakes go on, this needs assigning to the brake switch

To obtain the correct values of diff use this mix and adjust for best control, then delete it
You could also use the rudder trim lever to adjust the value of channel 14 giving you adjustable diff, if you disable the rudder trim on the rudder mixer

I like this mix, 100% diff drops the nose a little and gives positive yaw, good for turning into a thermal, it is possible to roll my Supra with full brakes deployed.

Aileron to flap mix

This is used to increase the roll authority, flaps act like ailerons

This can be a problem due to the extreme flap geometry and needs a curve, match the diff on the curve so that flap movement match the ailerons.
If you have calibrated linearized the flap travel you will only need diff

You could add another of these mixes to get 50% or 100% coupling, assign to a switch

Use minus weight for the second flap

You could use a 50% mix for general flying and a 100% mix for landing
