George I know exactly what encoders they use, Don't forget, I have three Zens here. There are DC motors and DC motors, I know what type I would choose and it would not be those Maxons, they don't have enough torque. That is why the Zen is so sensitive to balance. It is good for low weight...

In this thread we discuss the latest DJI autopilot/controller for helicopters and add to the Knowledge Base of all the newest products to come along for future reference.

George Maxon is what DJI are using but with an encoder. On the web site there are some incredible balancing examples of what they can do. If one looks at Cineflex for example the motors are of the pancake layout which make sense because the more poles you have the better the torque/resolution...

George It sounds like he is using a servo motor but without a gearbox.

Rob The whole idea of using the 250 deg/sec setting is so that you need less gain and therefor produce less noise. That is because you don't have to amplify the minimal output signal. Saturation is the enemy but it wont saturate until it reaches its FSR. The reason they make them is so that you...

Yes the WKM is a stand alone unit just for the gimbal. Naza-H will make helis almost as easy to fly as MR's. If you know helis it's no problem but if you only know NAZA-M then you need someone who has some experience. But with most Tx like Spektrum just select heli mode and your switches and...

Needless to say the Nex-7 is only there for the test flight. I have a much better camera now. You can see how fast the Zenmuse responds to sudden movements. You can also see why a lens shade is always required when you shoot near the sun and get a blade shadow hitting the front of the lens...

What kind of strange MR is that? and what is the gimbal.

Ah George you know what I'm like when I get the bug. I cant leave it alone until I have tried it. I would like to play some golf but not in the rain..... Thanks for the good wishes. I declined the full anesthetic so I could watch it on a monitor. It's not every day that you get to see your insides.

Rob As the camera base plate should not be moved at more than 5 deg/sec. with stick inputs, the 250 deg/sec setting is not a problem. I just heard from Alexmos that he is using the highest sensitivity setting on the 6050. But for other reasons it cant have the full theoretical output. It goes...

The Yaw will be reversed but you could fix that in the Tx. But the main problem is that the stabilising function from the main controller would be working in the wrong direction so it would spin out of control when you lift off. Unless the MC can be changed in the software. Get the soldering...

I would have to say that can only be determined but taking the camera and lens and seeing the balance point. I don.t think you should worry too much about longer focal lengths. Stay with very short focal lengths. 35mm lenses for example are very heavy. The method of outputting the video signal...

One of the best examples of autonomous control that I have seen on a MR.

I have Nex-7 with 16mm lens and also I have used the 18-55 on my Zen with some work. Both work fine if you balance in the mid zoom position.

Have you set the declination and the battery level and calibrated the gyro correctly. Did you move the model in the first 5 seconds.

In my experience the DJI controllers were way ahead of anything that I tried. But if you want an alternative try the latest DIYDrones stuff. But for one issue with 5.12 DJI was trouble free and it has the most advanced robotic algorithms in the business. I cant even begin to count the numerous...

The fact is that there are quite a few jerks and vibration issues in this video, it is not great. Given that the CX730 has smoothed most of it out. I doubt that the footage from that machine would have been anywhere near acceptable if the lens was not doing an incredible job. It is hardly Zen...
