I just had a job come in to shoot around 100 vulture nests at a military base to count the number of eggs, location is stunning cliffs and sea that nobody gets to see. Zoom lens of course. It beats commercial property work any day.

I have some reservations about both Naza-M and H, mine have a very small hole drilled in the side of the case to allow some air to move in and out The idea that the case not being a totally sealed unit seems a bit hit and miss to me as far as venting goes. I think sun light could cause a...

Thanks for that, It is definitely a driver problem. 48 is the last version that works it would appear. I have three different boards now so it will be interesting to see if anything is better than the Viacopter one... CSG finally croaked completely as I can see internal shorts in the board...

Those really nice people at Iflight just sent me a couple of their new GBM5209 motors. WOW these things are monsters. just right for those big cameras. Also got a Martinez board that seems to work just fine straight out of the box, however I cant get it to load the latest code as I get the...

I know how to design this stuff, the problem is that you need high end CNC machinery to make it, and that does not exist in Cyprus. What we have is expensive and worn out. Maybe I can get the Uni's involved again on the Turkish side. If I were thirty years younger I would go to China and...

This is what a moog valve looks like. It is the major motion control solution used in the aerospace world through to jet fighters, airliners and many other high tech devices including medical equipment. A few milli volts can be transfered into a force equal to 230 bar The EO24 moog valve used...

The Iflight 4006 motor is a good choice with 150 turns of .21 wire. I rewind mine with 2 strands of .20 wire and 85 dual turns. which improves the torque. A few years ago the F1 motor racing industry turned to the aerospace industry for new solutions for motion control. They discovered the...

If you want to be totally confused then there are quite a few MR's that can do a reasonable job if you know what you are doing. The fact is that almost all MR's have some level of instability in certain flight conditions. If you fix one end of the envelope then the other end will suffer. It is...

ADVANCED Calib. needs to be done in the right order finishing with the level. No need to write each one just hit calib. All other changes should be written after the change. You will know if the calib. was not successful because you will see cross axis mixing. i.e. your roll will change with a...

Thanks for the heads up on that.. Also this may be of interest, New 32 bit 3 Axis board coming from Italy. http://www.virtualrobotix.com/profiles/blogs/vr-gimbal-is-coming?xg_source=activity

Maybe you could use the HiTec HS-M7990TH servos. powerful and vibration resistant.

Ha, so they did not see that, whatever next. "Safety is no accident" just became "safety is no upgrade from DJI". OR did they simply increase the rez. and you now have to respan the calibration.

And now, you want everybody to go off into the wilds with their unreliable DJI junk to make films of mountains and deserts or whatever to glorify your crap products? You are a despicable company." Ah but they did say keep away from people and built up areas. Perhaps we should have our own...

Interesting that one battery in parallel would stop the other one unless one of the wires caused a direct short. That would have caused a fire!!!

Correct, far too many people cant be wrong... He also sells a 6050 imu board for three times the price, don't buy this one as he does not have or understand the need for a data sheet to go with it.

Having been satisfied with Naza H and firmware 1.02 I missed out on 1.04 but just got tempted to try the latest V.2.00 I hope that my last piece of DJI's wonderful flight experience is not about to turn into the usual crap. If it does, you guys, and the rest of the world, might get to hear about...

CSG He is known around the world now as the scamming little C***

The gimbal is only one part of the deal with Alexmos controller. It is also the easiest part to design. What you have to do to get it working with heavier cameras is to use motors that will work with a reasonable power setting i.e. around 200. FWIW I use the iflight 4006 motors wound with two...

Pete I have not had the time to test any MR's recently but I expect that a 15x4 from APC would be a very good prop. to start working with.

As soon as you open up the availability for something that can fly and take imagery then this will happen more often. Glad to see DJI at the center of bad publicity once again. http://www.marionstar.com/article/20130430/NEWS01/304300023?gcheck=1 I think his prowess as a director of aerial...
