Speed proportionality of the gimbal movement (the change in the rate it rotates up or down) is very important during video shoots. Rotate the wheel a little, and it moves slowly. Rotate the wheel a lot, and it moves faster.

After doing a Titan mod, I recalibrated the RC sticks. That calibration includes the gimbal up/down wheel. Since then, I've had a problem that the wheel had no speed proportionality in the down gimbal direction. It was full speed, or nothing. Up direction was just fine. I thought I messed up the wheel when I took my controller apart! This issue is separate from the gimbal gain settings. No amount of settings would fix my speed proportionality issue.

I just figured out what went wrong. When it calls for the wheel calibration, you rotate it left towards the blue dot, then to the right. My problem is that when I move the wheel to the left, I did it slowly and with very little movement. DON'T DO THAT! Move the wheel quickly and the full rotation of it's travel.

I just did the calibration first doing it slowly. It lost all speed proportionality in both directions. Then I did it full travel and quickly. It fixed my problem. I can now move my gimbal slow or fast, and I don't have to buy a new RC!

Nice! This is something I’ve always wondered about actually. Recalibration now

I hope someone else confirms my findings. And I’m not sure if it applies to other DJI models.

Well I always did the same thing as you. Did it very slowly and I find my wheel to be extraordinary sensitive. I have my gimbal speed at 2 and my shooting at 26.

I hear these tutorials that say to have gimbal speed at like 14 and smoothing at like 16 and that’s seems so fast I couldn’t figure out why anyone would want it that fast especially for cinematic shooting. It was mind boggling to me. Even with it at 2 I have to do it ever so softly. I’ve just gotten use to it I guess. Maybe I know why now

Thanks, I didn’t think about that. Since I’ve got the wheel working, I’m going to revisit my gain, etc. settings.
 
FYI... This morning I modified my gimbal wheel by adding a lever for more precise control. I just cut a grounding connector, epoxied a rubber tip to it, and cyanoacrylate glued it to the bottom surface of the wheel. I have so much more control, I can turn my gain up to get fast rotation, yet I am able to be precise enough for slow rotation.
