gimbal question - foward/backward not as stable?

    Got the cheap gimbal off ebay hooked up. It's a basic aluminum frame with I think the BGC 2.0 or 3.0 controller.

    Horizontally, it works great. Very smooth video when flying sideways, and motor is very fast and anticipates the craft's movement perfectly. The rubber balls also seem to work great at reducing the jello effect. Now however when flying forward and backward, is not quite good. The motor (I think it's the pitch motor?) seems to be very slow. When I'm hovering, it's fine to stabilize the video. But when I fly forwards or backwards, it doesn't seem to work. It's like it doesn't "catch up" to the speed of the craft tilting forward or backward. In fact, it seems to almost travel in the direction the craft is tilting, and not reverse like it should.

    Is this just the nature of gimbals (having never owned one before) or is there something wrong you think? Is there a setting I can change? I will also say the first controller I accidentally fried by hooking it up wrong, and replaced it with a new controller. I did not replace the sensor board, only the control board, maybe that is the culprit, maybe I should replace that too? But before I get another one of those, I want to make sure this is not just how a gimbal works and/or there's no settings to change. And yes, I did make sure craft was motionless and level before hooking up battery.

    Another question while I'm at it, please guys if you will! Last question I promise - the gimbal strap is made for a hero3 camera, I have a hero2. While it works, it doesn't stay snug and the gopro is not as secure on it as I would like it to be. The gimbal type is just the type where to gopro rests on a platform. I was wondering if anyone had any creative ways to make it more secure without permanently attaching anything to the gopro.


    Thanks team! :)

    Well I downloaded simpleBGC GUI to see if maybe there was a setting that would fix the original problem, but I messed the settings up royally I think. I ended up "loading defaults" but it seems to have loaded the defaults of the software, not the default settings that shipped with the control board. Now I got the gimbal to work again at least horizontally, but it's not smooth and vibrates, I think maybe the P I D settings are too far off now or maybe something else in the software somewhere.
