The bad vibrations caused by FPV driving are what turn a lot of people away from it cause it can be nauseating. Stabilization technology is getting closer to being able to completely solve that problem. Shout out to Chadd Rains for showing off this gimbal and testing it in his latest video. It indeed works pretty good with some major issues to work out. I noticed the same jitter issues and it becomes much worse in FPV mode. It's manageable at slow speeds but that's not going to cut it. I'm not sure firmware updates could totally fix that given the gimbal is having to do a lot more work on an RC car. The 'fix' I went with actually worked better than I thought it would on the Big Rock. That thing just has too much jitter for me to think any gimbal could stabilize it completely but it handled it well. At the higher speeds I could see some bad vibration come back but that might actually be due to the slack in the pan servo I didn't get rid of before the test.

Aside from these issues which are probably mainly at the ground level, the gimbal itself is an impressive piece of engineering. It's pretty small, has a nice build quality, stabilizes well (when not jitter bugging), and is extremely easy to configure using their application.
After getting it wired up properly you can get it all updated and configured in just a couple minutes or less. Doesn't take any special gimbal knowledge or anything, but the downside to that is you do not have full control over all the limits and what not. You're setting control modes for 3 channels and that's about it.

The second test showed that I was able to get a 'locked' FPV mode without too much jitter in the Yaw until I really started to give it trouble. This truck produces a ton of bad vibration when it gets up to speed because of the tires. I'm surprised the gimbal can actually keep up to some extent and make it bearable. On a buggy with really smooth suspension I feel like it would work almost perfectly on or off road. Maybe some other option will come along that proves to work flawlessly but until then I'll stick to using this setup with the annoying tape caveat. If they ever fix the issues with a firmware update I can just change a couple connectors around and use the then disconnected pan servo to just trim the front facing alignment. As far as mechanically locking the gimbal Yaw there are probably a ton of different ways to go about it that don't involve tape. Some type of small locking clamp for example.
