I have been using a 12x for planes, but am programming it for the first time for a heli and have run into two problems.

First, I hooked the gyro gain into Aux 2, selected gyro on the device select, but it would not work. It was assigned to the mix switch. I moved the gain lead to channel 5 and everything worked perfectly. I am clearly missing a trick in setting up the gain on aux 2. Any thoughts?

I am also trying to get the hover pitch trim to work. I can get hover throttle control to work, but not pitch. I understand it won't work with flight modes other than "normal", but that's where I have it set. I have tried assigning the hover pitch to both the knob and the left eyebrow trimmer, but this does nothing. Any thoughts on this one?

Thanks, Keith.

If I remember correctly, the knobs were only active (or the most active) at/around mid-stick because that was where hover use to be flown at (mid-stick). Today, it seems that even beginners are skipping this step and going straight to setting up hover at 75%-ish stick and setting mid-stick to 0° pitch.

If memory serves, the knobs adjusted the middle point of your pitch/power curve because this point use to be associated with the hover point on the curve. On an old 3 point curve, it adjusted the middle (hover) point (50% stick). With a 5-point curve it adjusted the 3rd point (50% stick) ... again this use to be the hover position for beginners.

So, even in "normal" flight mode, if you have the "normal" curve set so that 0° pitch is at mid-stick and you are trying to adjust the knob to affect your hover pitch (now at 75%-ish stick), then the knob will probably be disabled or have little affect until the stick is in the area of 50% stick (0° pitch). Flying with 0° pitch at 50% stick (not that there is anything wrong with this) has made the hover pitch/power knobs practically useless.

If you are flying with a curve where hover is at 50% stick, the knobs should be used to make the heli flyable enough to let you know how to adjust your curves. Once the curves are set correctly (or at least suitable), then disable the knobs. The position of knobs can be bumped or moved. Can you imagine the head-ache of relying on the knobs to be in a specific position in order to fly?

Ween yourself off of using these knobs as soon as possible.
Good Luck

Thanks. This my understanding of how things should work. But I can't get them to function.
