hi guys, I have been using a servo reversing y harness to run dual elevator servos - but suddenly it seems to have stopped working - when I switch the rx on the servos deflect and jitter all over the place - and do not respond to elevator input at all. I first thought it was a high voltage issue, but both servos are working fine when connected directly.
My question is - is there anyway to use the mixing functions on the futaba T6xap to run dual servos on elevator? I tried the p mix and ailevon function. On the former servo travels in right direction but only one way - either +100 0r -100 but not both. On the ailevon it travels both ways correctly but also activates the ailerons with elevator input.  Bang Head

Any advice would be greatly appreciated!

Connect one elevator servo to channel 2 and the other one to channel 5 (say).  Then enable PMIX1 with Master as Channel 2 and Slave as Channel 5. Set the rate as 100% and Switch as ON. That should do it. 

You may need to reverse channel 2 and/or channel 5 so that they move together in the desired manner (you can achieve the reversal with setting the rate to -100 also, just play with it until you get it right).

yeah tried exactly that. On the 6xap what happens is that the slave channel goes 100% in the right direction one way but not the other. I.e. it has half the travel of the master - so it returns to neutral but does not travel in the other direct. for Example I have full up elevator (on both el. halves) but full down only on the master.

If there is no programing for dual elevator set up on the 6 xap is there anyone selling a servo reversing y cable locally?

In that case, try enabling PMIX2 also, and do the same thing, except do the rate as -100% (you will have to figure whether PMIX1 is 100% or -100%, and vice versa).

Never had to do this on a Futaba 6ch. Curious as to whether this worked ?

This is easier on the 7channel and higher.

Apparently the radio is a the older (non "super") version, which has only one PMIX Sad  So the servo reverser is the way to go. 

I did test the dual PMIX setup out on a 6EXAP (the super version), and it works.

Refer to this video to reverse a servo..
