It's hard to know who is copying who, but these guys are in front alright with the flight control algorithm and the quality of production. probably funded by military contracts. I doubt that they are much interested in sales outside of China. (beer money)

Been using it for a couple of weeks and no problems.

All of the Blackmagic stuff is great.:tennis:

Only My Gopro

Juri So long as you avoid multiple grounds.

Timecops little 32 bit controller is a great little board that does what it was designed to do. However the camera gimbal outputs will not do the job properly. You will see a cross axis output interference across roll function. I think the guys at the Afro site are working on that.

Strange comment. In this video all of the shots were stabilized with DJI Naza and WKM standard gimbal outputs. The trick is to have gains close to 100% and then have your servo drive ratio to about 5:1 I have used the outputs from the AMP-2 that also work fine, you just have to know and...

At least DJI tell you that it is pre-order. The Chinese law protects these people from this type of scam. a company called Simply Electronics will take your orders and money then send you nothing. After a few weeks of credit card hassle you get your money back (if you're lucky) but they have...

The solder pad coming loose is quite common, especially if it was overheated when the joint was made. I have always used a manifold style wire harness which is the most reliable way. IMHO. It is also easy to incorporate a good quality switch.

I'm not taking that chance. Already got a mold underway. These guys are taking the piss.

I returned to the test track this morning to try a different gimbal and DJI's 5.08 firmware. The footage is raw from the camera and the IMU is from the WKM gimbal outputs. Motors and ESC's barely warm, About 12 mins duration on a 4s/5,000 ma battery. The F1 is a very stable quad but...

My thinking on the idea of having top one way and bottom the other is that when you yaw left the response is going to be different to right -Right? One set will be more dominant than the other, I expect. Yaw response is very critical of any prop differences. It could try to rise in one...

Yep. That fixed it alright.

Well I'm not trying to be critical of your design Bart I hope you can do well with it, This was a discussion about the merits of various configerations. However if you're really trying to be convincing over safety shouldn't those props. have guards around them and get the weight down a bit with...

Given that a coax is less efficient than one slightly larger motor that can deliver that same lift, it has less moment of inertia. Two motors on two arms is more efficient than a coax. and has a better distribution of lift and torque reaction. In order to yaw the aircraft in a stable manor the...

That is very impressive Ed, I would like to upgrade my Naza but cant find anyone who has actually got any stock.

Sorry I got that wrong. However in an email from Eric Sun received two days ago he says....."In addition, so far we only supports Sony NEX5n/7 with 16 mm lens." in the last paragraph he then says " We don't have Panasonic GH1 support any more." So I guess if you want your GH1 gimbal anytime...

Thanks CineRebel I will try that.

I tried 5.08 yesterday and it seems to fly ok but none of the motors start together very strange as it seems that two of them aren't going to start until almost at take off power. This did not happen on the earlier firmware!!!
