Simple question – is 'level' purely defined during the IMU calibration process
Hi Marian, Thanks again for your feedback :-) I will try doing as you suggested the next time I go flying (calibrate first with the camera tray perfectly level). Cheers! David

Simple question – is 'level' purely defined during the IMU calibration process
Ah that's interesting, many thanks for your feedback. So you're saying you take your calibration rig with you when you go flying and if you see the horizon starting to drift / move with the yaw axis for example, you land and re-calibrate …

Start-up routine for gimbals using follow mode on the yaw axis
Ahh I knew there had to be a simple explanation! Thanks very much for your help Marian, I will report back with my findings :-) Thanks again, David

Hi Marian, Thanks for the tip! Do you just do a single axis calibration when you use your rig? Whilst the 6-axis calibration feels more thorough, always having to remove the sensor from the gimbal to do it is a pain. Many thanks, David

Hi MdG, Many thanks for your detailed reply, it's much appreciated. Unfortunately I don't have a free radio channel or your idea would have worked very well. I was test-flying the gimbal last week and found it quite satisfactory to unpo…

That's great, thanks for the tip Garug! I wasn't aware of those RC initial angles ... as you say, not an ideal solution, but it might be sufficient in certain circumstances. Thanks again for your help :-) David

Nightmare with multiple Profiles
Hi Alex, Thanks for chiming in :-) Unfortunately I still had no joy switching between profiles after loading settings from a file and then writing them to the board. I've found a way around it though by manually entering all the parameters …

PWM pitch control not very linear, and extremely difficult to set the min/max angles accurately
PS. Ok I've just found that if I increase the Pitch value for 'I' it removes the delay ... it's a work-around I guess and the gimbal still seems to behave so I'm happy for now :-)

Hi Marten, Many thanks for your reply. Unfortunately this didn't seem to make any difference. Actually instead of undershooting, inverting the motor direction makes it overshoot (going beyond 90° down and then coming back). I tried auto-detec…

Ok so now that I've managed to re-flash the FW I can return to this issue I'm having. Unfortunately re-flashing the firmware didn't do anything and the problem still exists :-( I've even tried using the PC GUI instead of the Mac…

Firmware Upgrading - Failed to upload: Error writing firmware: Flash tool execution failed (1)!
Ok so repeating exactly the same steps that I performed on the Mac, on a PC with a Bluetooth dongle, the firmware upgrade worked perfectly! And that was with no special setting up / changing Bluetooth parity or anything. I'm quite baffled why …

Do you have any thoughts on this Bluetooth connection problem / firmware upload procedure guys? Many thanks :-) David

Firmware Upgrading - Failed to upload: Error writing firmware: Flash tool execution failed (1)!
Just as a PS to this, is there any way of configuring the Bluetooth connection in the GUI, like setting the parity? I've just downloaded a simple serial terminal program called goSerial which allows you to specify all the parameters for the Blu…

Firmware Upgrading - Failed to upload: Error writing firmware: Flash tool execution failed (1)!
Hi Garug, I searched on this forum (and Google too) but couldn't find any details on how to change / check the parity of the Bluetooth on the Mac. Do you happen to remember where you saw the details? The only PC we have in the house doesn'…

Firmware Upgrading - Failed to upload: Error writing firmware: Flash tool execution failed (1)!
Hi Garug, Many thanks for your quick reply and for the information. What drivers do I need to install to allow me to successfully flash the new firmware to the board? I'm not using a USB cable as my Desire RC board doesn't have a USB soc…

I'm also stuck in exactly the same position as TheMasterSii ... I have been experiencing problems with corrupted profiles and was advised (by Garug – ah who's also posted in this thread!) to erase the EEPROM (which didn't make a diffe…

Sounds like a good suggestion – I'll do this when I next have the gimbal to hand. Thanks again for your help :-) David

Nightmare with multiple Profiles
Hi Garug, The only reason I think it's corrupted is that the gimbal starts going nuts as soon as I load a previously saved profile (as in the video)! I'm using 2.43b9 and it's a V3 32-bit board from DesireRC: http://desirerc.co.uk/…

Hi Garug, thanks for your prompt reply! I'm not quite sure I follow your suggestion ... at the moment I've got a profile saved to my HD with settings that work. If I load these into a profile position (eg. Profile1 or Profile2 from the dr…
