GOODLUCKBUY 2 axis Brushless Gimbal Maiden flight

[Gav]

Well I could not hold out any longer and after cart wheeling my quad with servo operated gimbal which stripped all the servo gears - I decided to swap over to brushless direct drive.

I went for a goodluckbuy gimbal with motors and controller pre assembled  like this  http://www.goodluckbuy.com/2-axis-gopro-2-3-brushless-camera-mount-gimbal-with-motor-and-controller-for-gopro3-aerial-photography-.html   your fault Craig for telling me goodluckbuy had a good selection of gimbals now.

When it arrived I placed on my GoPro Hero HD 1 and powered it up with a small 3s lipo, the motors were making a very annoying high pitch squeal and not holding the camera weight at all - it was struggling to stay level.  So I decided to reflash the firmware and take the plunge into adjusting it from scratch.  I also connected a servo lead to A1 (pitch signal) and GND on the Martinez board so I could control the pitch in flight with the slider on the transmitter.

With thanks to  Pete';s (sausageroll)  gimbal thread http://www.multi-rotor.co.uk/index.php?topic=2291.msg21918#msg21918and Gary';s (Gaza) help too - I got the gimbal working with V49 firmware and V48 .exe adjustment tool / GUI. :) 

Here';s my maiden flight using default PID settings:

Nice one Gav

Gav - I';m struggling to get the rc control to work for mine.

Did yours come all wired up ? I';d asked for mine to be - and:

1) frecking IMU was upside down and sideways (which is now fixable with latest firmware I see, but at the time I hadn';t realised so had to remove and reattach).

But the servo wires for (I assume) pitch control were wired directly to the board - to 5v, gnd and to an output from the actual arduino chip directly??

it';s working great now with latest firmware, except for the RC control which does nowt.

So, I tried removing the signal wire from the chip and connecting it to A1 - still no joy. I even disconnected the 5v so just A1 and GND but still nowt.

any ideas ? is A1 adjustable ? maybe the latest firmware expects some other input to be used ??

stu

p.s. I really hope they don';t change to bloody UI completed again with the next release - getting a bit sick of having completely different UI and parameters with every bloody release...

Yes I disconnected the wires for pitch control because like yours, one wire was directly attached to the atmega??   A1 signal and GND on the board connected to channel 6 on the receiver.

Moved the sensor as per photo:



Also is there a box to tick and gain level to adjust for the pitch movement, on the gui?  I';ve not got round to looking at that in detail yet.
