Hi guys well I've finally finished the installation
of the tailerons on my F16.
You all know the one I mean, The one that crashed every flight because
of slop in the tailerons(elevators).
I've installed each side on to it's own servo and the whole assemble is now much more stable.
Need some suggestions on how to set up the mix on the dx6i transmitter.
Here's how it is at the moment.
Ailerons are controled by a single servo plugged into aileron input on Rx.
They work fine and always have.
Right taileron/elevon(whatever you want to call it) servo is plugged into elevator input on Rx.
Left taileron/elevon servo is plugged into gear input on Rx.
No servo reverser or Y cable needed.
Mix 1 on Tx is set up as elev -) gear ACT
second line reads Rate D +100% U +100%
third line reads SW ON Trim ACT

Have not set Wing Tail Mix to anything.

Now here is what's happening,

When I pull back on elevator stick both elevators come back.
When I push forward on elevator stick only the side connected to elevator input goes full forward, the gear imput side only moves about half way.
I've played with things like servo travel adjustment, endpoints etc but can't get it to go any further forward.
Also, gear switch has to be always on for the gear side elevator to move in correct direction, if I switch the gear switch off the elevator connected to the gear imput snaps to the full up position.
Tried reading up on this on the web but all seem to talk about mixing with ailerons and the elevators doing a dual role.
I'm only wanting them to act as elevators.
If anyone has any ideas I'm all ears....

thanks

Paul

Forget it,.....................It's working.
Found a article on the net that told me the secret.
I had to create another mix on the Tx
Mix 2 Gear -) Gear Act
Rate U -100% D -100%

This has the effect of cancelling out the gear switch and also allows the gear servo
full travel in both directions.

I now have the Tailerons working as I want them.

I still would go with a Delta setup for the tailerons and mix in the ailerons separate.

Sounds good mate, but I'll have to leave it until we meet up at the field.
At the moment I've got it working as the original bought setup was suppose to work.
I believe if we mix the tailerons and ailerons we might have to reduce the aileron control surface travel as the tailerons will take on the major part
of the rate of roll.
I'm no expert so I may be wrong here just trying to remember some of the things I read on the web.

Had another look on the web.
Don't know if I can do that mix as the dx6i only allows 2 mixes.
Think if I had a dx7 I do do as you suggest.
Problem is that with Spektrum all the switches are enabled
by default, so if you don't use a mix to counter this you can't
get that channel to work properly
Anyway if you know of some other way to do it I'll give
it a try.

Hey Kieran's the man.......
After a MSN session earlier this evening I've now got the
Tailerons and Ailerons working just like the real thing.
Solution:
Elevator servos into elevator and aileron channels.
Wing Tail Mix set to Elevon
Aileron servo into aux1 channel.
Mix 1 set as,
aileron -) Flap ACTIVE
Rates Up 100% Down 100%
Switch On Trim ACTIVE

Then in Dual Rates/Expo set Expo to around 60% (Users choice).

That's it ....Easy (when you know how).

Thanks Mate.
