Rob What I do with SRH drive train is to look at each stage from just the motor to the final assy. with the I phone vibration App. The tail rotor can be a problem but I don't use a conventional drive from the main gearwheel. It is just a motor fixed to the tail rotor assy. running at constant...

Tabb has about ten state of the art helis but prefers his own MR's. I currently have one very special heli and it is going to be the first of many more. Including one that floats. As I proved with the F1 MR's, if the model is really steady you can get away with no camera mount at all. Nothing I...

Autogyros are really safe compared to helicopters. Always in autorotation. I think the guy flying the big heli is working to a tight budget. Turn around takes too much time. Crop dusting is like pylon cleaning. You get paid on results. It causes accidents as profit and time get pushed to the...

When it is doing it's calibration it must be connected to the powered up WKM. Boris that video shows you were in FPV mode so the pan heading slaves to the models heading but it also has some degree of Pan stab. You cannot start/stop the video in flight only take stills. Video should be...

The difference is that the Av 200 is a total waist of money and the Zen works. 2,500 is far too cheap for what you get.

Well it is a function of what people will use the camera for, that is the main point. For night aerials it does take some beating as a stills camera. But for people who want to use it for semi amateur video work it is a huge weight penalty with no real advantages. I have seen some work from a...

I had one fall from 120 feet into the sea, it smashed the front element of the lens on impact. The Zen was not broken, the only damage was oxidization on some electronic parts due to the salt water. The Nex-7 will never work again. despite everything being washed in fresh water within five mins...

This gimbal system is clearly an uprated Zen. It is not that difficult to do that if you understand how it works. These guys have gone to a great deal of trouble to show you how not to operate a zen. Most of those camera moves are too fast. If you use a cinematic camera like that the strobing...

What is the bit rate of the CX730. For aerial filming this is more important than sharpness which can be dealt with in Post. What limits the Nex-7 is the speed that it can refresh the screen. I was considering a 5D111 but then for under 3K I could get a Black Magic with EF mounting etc. Canon...

Well done Ed some things in life are more important than AP ...

I think it was that part of the code that had a bug. Only guessing though. For sure 5.10 had one in that area. Once initiated it could not be cancelled. It also had a habit of dropping like a brick when starting a slight descent- sometimes all the way. Could have been something to do with being...

I seem to remember he had to fly through blood and body parts when the other guy above and in front hit the bridge.

Another variable to throw into the mix is that a lot of specialist aerial lenses are corrected for best performance at around infinity and for linear distortion. It is much easier to map (Vertical) without having to add large correction factors. (Calibration) Studio lenses are not much use.

I would rather have one of these, Made in Japan..... Chemical spray shows the vortex quite well.:tennis:

Before they released this batch of Skylines they said they were having trouble with the casting of resin around the board. Was that problem ever fixed or did they just send out the faulty ones with the so called good ones. As quality control does not exist at PH who knows what we have.

You could buy 10- Z15's with the time that you will spend with crap like PH and a lot of others as well. It is the most straightforward way to get instant results. There is other stuff that can do the job (Mil.spec.) at ten times the price. When the likes of PH say we will have stepper motor...

When your ambition is to upload it to YouTube why the concern over a slight drop in quality at 1080. Why do you think that this movie defaults to 360 P for general viewing. http://www.youtube.com/watch?v=I1fQ-3-CEFg&feature=autoplay&list=UUsO1AOwtvyPFWnxDNy9pMqw&playnext=1

Pros who earn a living from this do have an entirely different viewpoint even though at times pros like to play around with a few toys. It would be a great idea to segregate this. It will give the newbies something to aim for and the pros something to consider and contribute too, doubtless there...

Nothing that I could say was 100% certain but I did have this problem after 5.10 and the unstable software which could have resulted in a firmware corruption. Point is that all is well now and DJI did a great job. I guess that keeping customers happy is a difficult job at the best of times with...

Zero UAV Do you have any close up details of the Steadi470 Stroudmire aerial system yet.
