I too am trying to find the ideal motor to power a gimbal for the Sony NEX-5N camera. It appears that either JussiH or Bricobrac may have some custom motors available soon so I am waiting on that announcement as I would prefer to not have to wind motors.
I used www.posten.no for tracking I think

Funny that mine arrived on short time but yours still not shipped? Did you contact them ?

I need to find a motor that will work for the gopro if anyone got a hint then I would be happy...

I also got a nex5 but that one need to wait, I don`t have a anything to lift it with yet.
Winding motors is something that takes time but it`s not hard to do it, I did it 4 times on the hextronik motor and used 4-5 hours on it to get it right. But if i try to do a new one now I think it will go faster

The only thing to comment was that the sda scl on the mpu was reversed. But no problem just uploaded the latest firmware from alexmos and did a test
Now I need to find a good engine to rewind and build a gimbal I have a cnc mill also to build so I can mill some parts for the gimbal.
How can you tell if its revesed?

I just picked it up in a thread and did a check before I tested it. Just run your gui and you will see if you get any reaction when tilting the sensor, you can also look at the silkscreen on the MPU and check it with this picture. On my sensor the SDA SCL was reversed, the picture is the correct pinout.

The first thing I did was to upload the newest firmware form alex. 1.2b.hex
http://www.simplebgc.com/eng/downloads/

Then I did the test and it just worked, if the you use the 1.2 Gui on a 1.0 firmware i think you will get some problems. If I remember correct this was the case for the multiwii firmware to, you need to run the GUI that is designed for the firmware.

You can try to download the v1.0 and v1.1 Gui and see if that works if you don`t wanna flash a new firmware to your board. If it still not working check all your connections and also read the tuning manual, you may miss a driver for your ftda usb adapter?

Got it working now. There was to long cables between the card and the sensors.

Rewind a Turnigy 5014 with 130 turns of 0.2 wire today. The resistant was 14.7 ohms so its in the upper limit. Tried it with the controller but it was not smooth and it run a little hot with 100 in power...

Got a CSG board coming in the mail and starting to figure out parts.
I'm going to build my own gimbal very simple and light for a Hero 3 Black edition.
I have an old eflite 370 park motor lying around and was wondering if it'll have enough juice when rewound to manage the tilt?

Thanks

The Park 370 is 28mm O.D. and has a 22mm stator in it. If it is a 12 arm stator it would be a potential candidate. Others have used that size and it worked.

But here on this forum, the E-Flite motors have a terrible reputation as far as being candidates for rewinding because their windings are normally heavily saturated with an epoxy glue. Many have reported them as being nearly impossible to strip without destroying the stator the coating on the stator.

I have not actually had one in hand though, and some of us are more patient than others (or is it stubborn?) at getting the windings off. It you have one it would be worth taking apart and giving it a try. But try it with a micro torch and working carefully and patiently to find the ends and work them backwards as I describe in post #5.

I can almost guarantee you they will not respond to the a brute force attack for winding removal.

I was in an VIP auto parts store yesterday and they had those pencil type micro torches for sale, two in a package for $5. Those, with a canister of butane gas for refilling (Home Depot, drug stores, etc.) is a very useful tool to have around.

thanks Jackerbes it is 12 arm and it is lying around. I'll pull it apart some more and see if its keen to be unwound.

Jack,

Do you think 80 turns per stator with .2mm wire in y config will work with these motors?

One drawback is that "high temperature adhesives are used to secure the stator windings"
