Thanks guys.

First you disagree on either all heading gain stopping or just surface altered . . .

I was not looking for throttle control but rather the danger of 'nudging' the rudder and cancelling heading gain when using throttle. It seems to be safe it would be best to leave heading gain off yaw to avoid moving the throttle from disabling heading gain.

Could one alter the Priority on the yaw to soften its connection.

So guys does all heading stop or just the surface touched?

Once again thanks for your replies,

That isn't my understanding, but I'm happy to be corrected. I believe heading gain is deactivated for all 3 axes if any stick is moved off center (apart from throttle).

David, I think you are better off ignoring heading gain altogether and using just rate gain. My personal view is that heading gain is more gimmicky than useful, and can actually get you into trouble if you don't know what it's doing.

I just did a quick bench test to confirm that any stick movement deactivates heading gain in all 3 axes. Even more scary, the surfaces whose stick was not moved maintain the position they were in at the instant heading gain was deactivated! You therefore have to move all sticks to re-align the control surfaces to the stick position. Perhaps you and Dereck could perform the same bench test to see if your results match mine, in case it is a firmware thing.

I'm using an AR636.

Now you have me questioning myself. I am not sure.

Here is my experience. In a Knife Edge when I use the Elevator to turn, The plane does not drop the nose or need Rudder input to Hold the nose up. I cannot answer if that is because Rudder Convention Gain or Heading Gain holds it up or not. If in fact it is Conventional Gain is doing it, speaks loudly Conventional Gain should be used with Heading Gain.

Still learning after two years.

Dereck, the answer lies in the fact that deactivating heading gain does not re-center the control surface. So in your knife edge, when you move the elevator, the rudder stays at the position it was in at the instant heading gain was deactivated. At least this is my observation with my AR636. If you then brought the plane back to level flight without touching the rudder stick, the rudder will still be offset as it was in knife edge. You would need to nudge the rudder stick to reset it. Try a quick bench test, rotating the model while heading gain is set, then watching the behaviour of the control surfaces when you move one of the sticks.

Hi Derick and Splinters, very fascinating and when the wind drops locally I'm going to use my Graupner V Venture to test as I can quickly flip back to my safe (mode 1).

Let me throw into the pot that on my Delta Ray, which I know is safe/AS3X, hands off in mode 1 or press and hold panic button holds the plane in landing posture and one brings it in on throttle. Wagging the throttle (read careless movement) does not break the landing posture.

As I mentioned I guess a field test us the only answer to . . .
Q1 Is it all heading gains or just the touched heading gain that stops?

Thanks

Safe mode receivers are completely different animals in their operation. From what I've been able to investigate, they use only rate gain for the flight modes, but play some clever tricks in the firmware with heading gain to accomplish panic mode recovery and also limit the flight envelope in the typical Beginner and Intermediate modes.

As per my previous post (#53), all heading gains are deactivated when a stick is held off center.
