RE: dual elevator set up
Do you have the LINK and or TRIM turned on or off on your mix screen? Did you go to your AUX channel screen and make channel 6 NULL?
You can try both of these things.BUT. You really should be using ch 5 for the other half of your elev. Channel 6 is set up for your second aile servo. If you are using a Y harness that is fine, but if your radio is set up on a certain wing type, it will do funny things to channel 6.
