@ausdroid: I wholeheartedly agree with your points. I feel for the people who have been at this for awhile. It seems that things that are now easy used to take more patience & money. I hope the future of open sourced products will get easier to organize in respect to structured software and the documentation process. That being said, the Chinese have a great opportunity to make improvements on what is already available.
I have seen in Taobao,but I do not think open source pcb file.
I know this is an old thread but in my limited experience with this board, the vibration isolation system being used doesn't work well. It's appeared on the Copter-3.3 beta testing thread and it's very high vibration levels are so bad I've used the logs from the copter involved as a worst-case example on the Measuring Vibration wiki page.
On the plus side, it's allowing us to test the EKF in very high vibration environments :-).
Anyway, I guess my advice for people is stick with the simple 3M foam solution unless the alternative has real testing behind it to prove it works better.
