Taranis Camber and snap flap with even movements

This is needed as the geometry on the ailerons is not the same as the flaps

To do this Camber is put on a high channel mix

the left slider is used as an input controlled by a switch

The next mix is from the elevator with 100% diff  and on a switch, don't use diff if you want the surfaces to go up with down elevator
The I in front of Ele means that the value after rates and expo have been applied

The value of channel 15 is used as inputs to all the wing surfaces

A curve is used to get linearity, and repeated on the other wing surfaces so that the whole trailing edge goes down together
Some like the flaps to lower more than the ailerons

Adjust all curves to get even movements

Variable aileron rudder mix

With this mix the amount of aileron to rudder mix increases as the brakes are deployed

Channel 4 the rudder channel get its input from the aileron stick, the weight is set by GV4

Channel 15 is given a value of 50 controlled by the aileron to rudder mix switch, this gives 50% aileron to rudder

Channel 15 is added to by the amount of brake deployed controlled by the brake initiating switch

The value of channel 15 is used to set the value of GV4

This gives 50% coupling rising to progressively to 100% with the brakes on

Launch

This mix lowers the flaps and then releases them slowly on a timer, to use  lower the flaps with a switch and control the amount with S1, you then release the flap switch, the flaps stay down until the timer finishes, them the slow release takes over.
switch off the the launch flap switch as you release your model

Use the earlier camber control with variable aileron diff, this will give you no down aileron only up, the lowered flap will give a strong start, then it can pick up speed and you slowly reduce the camber to suit the models speed
When your model is travelling fast the camber is removed and normal aileron control is restored

Here the amount of start is controlled the value of channel 16

channel 16 is used for the timer, here it set to 2 secs delay with a 4 sec release

The next line multiplies the line above by the value of S1

Both flaps get an input from channel 16, you may want to add some extra down ailerons as well as the camber mix, this can be added to the camber channel, you need to reduce or remove the mix from start to flaps if doing this

If you want the whole trialing edge to lower with start just use start to camber mix

channel 16 is used to set GV4

An extra aileron to rudder coupling is used getting its weight from minus GV4

This mix gives you 6 seconds with extra flap, then you control the camber with the left slider. you may want to add reflex by adding a value of negative camber for the ping off
I like to add extra rudder mix for start and use the aileron stick during launch, the 100% diff introduces positive yaw to aid the rudder

if you have got this far, you should now have the hang of using mixers. Start again and get you model to do want you want it to do,

I don't like flight modes, instead the camber control does the job, penetrate when fully up, search part down, thermal when fully down with trim and diff set by the camber control.
On a 4 metre model aileron rates do not need to altered, the 100% diff on full camber does give a lower aileron response, the reverse diff on full brake restores the aileron response and with the extra rudder gives good control for landing
You could have a different surface control for each flight mode, this would be needed on an F3F model

landing mode is steadily applied as the brakes are deployed, altering the diff and rudder coupling.

Many top F3J fliers set models up for different ballast weights, this mix is just to illustrate a simple launch mix

I have let many people fly my models, with these set ups they find them easy to fly, a forward C of G, gives stability, making trim less critical

There are many sophisticated set ups for F3X model on the web

Flight Modes

These allow you set trims for each flight modes see this video https://www.youtube.com/watch?v=8H0wt_LR87Y

Rudder Trim

You may wish to use the rudder trim for another function like differential  aileron adjust or throttle / elevator mix trim
Here is a way of moving the rudder trim to the adjuster S1

A logical switch is set up

Here the logical switch 1 is on when the aileron is full right and SH the spring loaded switch is on

The value of adjuster S1 is used to set the value GV1 when L1 is on; use any GV that is not in use, SI has no affect when L1 is off

A value of 10 is set on channel 17 to be used as a value on the rudder mix

The rudder is on channel 4, this secondary mix gets it vale of 10 from channel 17 and its weight from GV1

If you wish to trim your rudder, hold the aileron stick fully right and hold switch SH on, you can then trim the rudder with control S1

You can add more of these to trim out errors in flap and aileron positions by using other logical switches

 using the same switch with fully left rudder, right rudder or up and down elevator stick movements to give 4 adjustments on other GVS use "a=<X" for negative stick
This will allow you to quickly adjust the trailing edge without going into subtrim

The combination of GVs, high mixes, functions logical switches and curves makes a powerful combination
