i everyone, I just bought a "Brushless Gimbal for GoPro Hero 2 3 DJI Phantom F450 F550 Quadcopter Aerial FPV" from Ebay.

The posting stated this:

This is a brushless gimbal for Gopro Hero2 or Hero 3. It is fully assembled with the frame, two motors, and Martinez control board with sensors.

This is fully assembled, but the balance was not done and PID was not configured. It might come with slight imperfectness, such as a bent pin, but nothing major. And that is why it is sold with this super low price (The board itself is $40 value)...



I am new to gimbal, i bought it thinking that i had to download a program, fix some values, some adjustments and thats it. i have read a lot, but to be honest, I'm not sure what I'm doing at all. It seems there are too many boards, software, firmware etc.

I uploaded on youtube a video of my gimbal out of control

At this point , i have no idea what I should do. I am not sure what type of board the gimbal has, what firmware is installed in it.

I would like to learn about this, but I need a "tutor" .

I really appreciate everybody's time .

I have no clue whats wrong with it but I can garuntee that the manufacturers know more about there own products than anyone on rcc

[nerwin]

Thats a board based on the martinez open source platform.

Here is a good start:

I have one of these on a F550. Once you get it flashed with the newest firmware, you can tune it with a gui, its not simple, but not impossible !

I can give you a hand if needed. No guarantees, but Im sure we can get it to work.

All my boards are alexmos, have no experience with Martinez. Like nerwin said, flash the latest FW and follow some of the guides on rcgroups. It will work but needs some tuning. I just tuned my latest gimbal tonight. Lots of little changes needed to get it tuned on the bench but it will smooth out and then your set for the first flight.

I can guarantee you that I can get more info from forums like this one than from the manufacturers , specially when the product is MADE IN CHINA.

BTW: I uninstall all drivers I had to try everything from ZERO again . My board is a "CP21-2 USB to UART Bridge Controller " ( this is what the device manager displays ) . I did everything what this thread says http://www.itsqv.com/QVW/index.php?t...Three_-_Tuning , but those drivers seems are not the correct ones for the board which I have . This is really crazy, I've tried almost everything . Please confirm if your board is the same than mine , or if I am totally wrong, please explain me a little bit.

Sorry, I cleaned up my inbox...

This maytech martinez board seems to use the same usb/serial adapter as yours.

Can you take an upclose picture of both sides of your controller so we can see if we can find out which one exactly it is ?
