Turnigy 9x – Xieda 9958 Throttle Curve

I recently purchased a Turnigy 9x and am in the process of setting up my preferred throttle curves for it. So I figure I’d share.

From my understanding, being able to set your throttle curve is the benefit of setting up the initial profile as a “heli” instead of “acro”.

To get to the throttle curve section of the menu, hold down the menu button. Select Settings. Then select THR/CV.

Currently, I have two different throttle curves link to my [Aux 3] F.Mode switch.

Owners of the 9x will know that the F.Mode switch can be toggle between three settings: N, 1, 2 correlating to Norm, ID1, ID2 in the menu.

Initially, I have a normal, more linear throttle curve set for the N switch position:

But I found that I like to fly with the ID1 position. It has the following curve set:

I think I will make the ID1 settings my Normal in the future. My ID2 position currently has a rudder to elevator mix that I am experimenting with. Being able to quickly switch between different settings in mid flight allows you to do a A:B comparison and makes it easier to find the combination of settings that fits your flying style.

I’ll post more as I complete setting up and fine tuning the Turnigy 9x with the Xieda 9958.

Side note: You notice that the stock 9x firmware gives you the ability to adjust 5 different points on the curve. Similar to the Spektrum family of TX. This is one example of where the custom firmware like Er9x shines. They allow 9 points on the throttle curve. For those who need absolute control. Obviously overkill for a micro heli like the 9958…but it’s one example of the power the Turnigy 9x posses with a custom firmware flash to it.
