I have set-up an Align 3GX v2.0 and all seems to be working as planned, BUT when I select flight mode idle up 1 on my JR 9303 the swash plate moves uncontrollably to nose down. If I swithch to Idle up 2 or back to normal all returns and works fine. Then if I reset the receiver and start in Idle up 1 the opposite happens, that is it functions normally and when you select either normal or idle up 2 it runs away full aft.

Has anyone seen this befoe or have a suggestion to correct?

You need to revisit your setup. The V2 is a lot different than the v1.2. I use the 3gx and it is flawless as long as you have centered your head and links and no trims. FBL does not like trim and thinks it is a control input. Some sub trims on the 3gx at set up is ok because you are setting up the head with it in mind.

When starting your set up set your pitch curve to 0-25-50-75-100 and your swash mix to achieve the pitch in collective say 11-12 degrees for a .50 size and 8degrees in cyclic.

Thanks, I will do that again to triple check each step. But why would normal and idle up 2 be fine and idle 1 run away.

I will set all pitch curves as suggested and try again.

I reset everything and set the curves as stated above, then repeated the setup procedure again. No trim anywhere and validated a level head with a physical head block. At the end I have the same result and problem. The idel up 1 has run away down trim, Normal and Idle up 2 are fine. If I turn on the reveiver in idel up 1 the Normal and idle up 2 run away nose up.

Totally stumped again.

Problem fixed. I did a total reset of the the transmitter and started all over again, and this time the problem went away.
