January 2014...which is the best brushless Gimbal for GoPro2?

[Silverburn]

Hi guys,

Ok, given the rate of progress of Gimbal design these days, I thought I'd ask where can I get a Gimbal that meets the following criteria:

- Lighter than a generation 1 RCtimer aluminium
- Is *not* an "L-shaped" gimbal. ie the mount tray is supported by a motor on one side, and a bearing on the other.
- Is compatible with a GoPro 2 but supports GP3 (I can't bring myself to spend money on a GP3 just yet)

I have a quadframe brushless gimbal (L shaped) on one rig, but I can't seem to get it optimised with a martinez board. It's certainly light...

Has anyone managed to get good results with an L-shaped gimbal? And by good, I mean "excellent".

Can't get optimised, what problems are you seeing?

A number.

1. When level, it has tiny, tiny oscillations on pitch.
2. Both pitch and roll don't respond fast/hard enough: I tried more power, more P, and just about everything. No joy - it still seemed to lag. I could get it almost right...then problem 3 would kick in
3. slow to return to level; like it was "sticking". Too much I I suspect.
4. Would not stabilise roll - even tiny movements would not be compensated. Put it in a hover, and the horizon will still move with the quad.
5. Even moderate forward flight would upset it

I checked all the mechanicals - it was tight. I eventually just moved onto an RCtimer, and it was running much better within 2 flights.

I'll upload the last video I shot with it soon.

SilverB,

I've read of different challenges with the gopro brushless class of camera mount and decided to buy the H3-2D and build a NAZA quad around it. I'm expecting it to work without the hassles but will report back when it's all up and running. There will also be a product review if you're interested in a week or two.

I assume you are talking about the Alexmos BGC. Tiny oscillations are not a PID loop tuning issue. There is another couple of parameters and one has to due with controlling the BGC motor torque or current. Adjust that to eliminate the tiny ripples.

The Klinker Aerospace FFBLG is lighter than the RCTimer gimbals, it is a L shape, but supports both GoPros

I guess that might be a nice gimbal, but its certainly a DIY gimbal and the demo video is not very impressive considering the kind of everyday video thats being posted in the CM300, Terot and the Stella threads.
