2.60b4 not tracking axis as accurately as prior builds
Maybe my problem is related to yours. I do not want to hijack this thread but I upgraded to the latest firmware as well and since than the YAW motor does not react to the Offset value in Follow mode. It initialises in what ever position it is upon p…

Follow mode yaw vibration mystery
That is exactly what I have done. Coppied the Angle to Speed and than just changed it to Speed and changed expo in the Follow mode. It is strange. I will check everything again when back home...

Follow mode jumpy
Thanks. I've kept the deadband low because I thought that it assures the gimbal returning to its direct forward position matching the aircraft's forward point more accurately. With higher degree value, I thought it might be too loose in th…

Follow mode jumpy
Yes,it works fine. I would have thought that it might be not enough speed. Speed, as I understand it, works almost like dumpening. The more speed the less the gimbal falls behind the airceaft. The more speed, the more closely the gimbal follows the …

Frame IMU placement / dampening
I have mine on top of the swiveling arm of the gimbal yaw axis just bellow and next to the yaw motor. Look forward to hear your findings.

32 board on LiPo 6s safe or not??
I guess the noise can affect the fpv transmission or even interfere with radio rx reception or GPS signal. Is there a way to deal with noise like putting a ferrite ring around the output wires or any other way of shielding it????

I found this http://www.hobbyking.com/hobbyking/store/__49470__Quanum_12V_5A_7_2_25_2V_Dual_Output_UBEC.html They say it is very noisy. Will it be ok?

Can you recommend any 12V stepdown regulator? How many Amp combined do I need for 3 motors RC Timer 4108.

help with yaw not centering on 32-bit board!!
I was going to suggest that too. it looks like the yaw motor does not have enough power. It is difficult to balance yaw axis and if the gimbal gets off level position it can take a lot of power to hold the yaw if the gimbal is not balanced properly …

help with yaw not centering on 32-bit board!!
Did you try different speed settings and expo? To centre the yaw is done with offset. Without the well documented pot modification you need to make sure to centre the yaw before power-up. Than it should center every time unless of course it misses s…

Simple question – is 'level' purely defined during the IMU calibration process
Remember that during the calibration process the sensors ( both camera and frame) must be fixed in position and kept still. Good luck!!

Simple question – is 'level' purely defined during the IMU calibration process
Adding to the previous. If the gimbal is properly built and all 3 axis are truly perpendicular to each other there should be no interaction between axis movement. To put it simply, if you only move yaw for example the tilt and roll should not move. …

Simple question – is 'level' purely defined during the IMU calibration process
No no no. I do not need to do it very often. As I mostly take stills the minor imperfection in horizon can be fixed in post processing. But if I see that the horizom becomes consistently off in one direction I simply recalibrate when I get home. May…

Start-up routine for gimbals using follow mode on the yaw axis
Those things are controlled by Speed and Expo. If you want to follow faster the yawing of the flying platform, increase the speed to about 60-80% of the range. In 32bit it would be around 170-190 from the range 0-255. You can go 250 in which case it…

Simple question – is 'level' purely defined during the IMU calibration process
No. Never did the 6 axis, as it is as you say pain in you know what. It is tricky to attach the IMU in perfect allignment with the roll and tilt axis of the gimbal to avoid interaction. Once in place I do not want to do it every time I see the horiz…

How to please: set pan always at 0° relative to frame in follow mode?
I make sure the gimbal's yaw is in the close to zero deg heading position upon power-up. Once inicialized, fine tune the 0 deg heading with offset in Follow mode tab in GUI until the gimbal's heading is alligned with the frame heading. Tha…

I am using Digital Pitch Gauge 2 by RCLogger which measures level in two perpendicular planes at the same time with 0.1deg accuracy. I put it in place of the camera, turn the motors off and fix the camera mounting plate in perfectly level position i…

Ok. I probably leave it out and concede this is as not working on my board. I tried everything and nothing seems to be making it work. As you said, with two IMUs on gimbal it might not be important. Is there any way except the potentiometer mod to…

I have it configured exactly the same way as I had it on 8bit. Nothing has been changed. I pretty much coppied the settings from 8bit to 33bit. It was all working with signal wire only connected to RC pitch from Rx and FC Roll and FC Pitch from F1 a…

The pitch motor is buzzing upon tilting down over 45deg. I performed the Auto calibration with the slider all the way to the left for stability. Any way to stop it??

I worked it out, well in part. I made the tilt function working from my Tx by adding the GND wire between Rx and the board.. But the FC Roll and FC pitch signal is not seen in GUI even with GND and signal wires connected to the Naza FC F1 and F2 por…

I guess it is a bit different on a flying platform where I do not want follow mode on pitch and roll axis. I just want the roll and pitch stabilization to work as accuratelly and as fast as possible to hold the horizon perfectly level, no matter how…

Not sure about the follow offset calibration but I use small amount of offset ( about 15) with 8bit to get the gimbal facing straight forward upon initialization. That means that the camera lens is perfectly aligned with the forward axis of the dron…

Thanks again. That is very useful info. Which auto tuning option would you recommend for a flying platform (Hexa) mainly for shooting video to get good horizon holding and nice fluid motion?
