Hi, I searched the forum but didn't find anything looking like my problem. I maybe did something wrong in my setup. If not, it's maybe a defect servo. Let's see my specs and videos to understand and perhaps help me. Aircraft Type: CS6 Gimbal Type: CS 2 axis Radian Type ( 1, 2 , 3 axis) 2 axis Gimbal Power source: 3S Lipo via 6V BEC Gimbal Radio Type: DX6i Radian Communication Protocol (S.Bus, PPM, PWM, Spektrum) Spektrum Connections: Change these to match your setup Roll Sensor: Port 1. 6V Power 2. 3. To Tilt sensor 4. To Roll Servo Tilt Sensor: Port 1. From Roll Sensor 2. 3. 4. To Tilt Servo Pan Sensor: Port 1. 2. 3. 4. Symptoms: Roll vibrates more during left compensation. See the video to understand: <iframe src="http://player.vimeo.com/video/62728975" width="500" height="281" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe> <p><a href="">153879466</a> from <a href="http://vimeo.com/user17319282">TechStuffs</a> on <a href="http://vimeo.com">Vimeo</a>.</p> Before you ask... Yes the gimbal is balanced: <iframe src="http://player.vimeo.com/video/62728973" width="500" height="281" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe> <p><a href="">153896428</a> from <a href="http://vimeo.com/user17319282">TechStuffs</a> on <a href="http://vimeo.com">Vimeo</a>.</p> Uploaded with ImageShack.us Uploaded with ImageShack.us Thank you for your help.
First post edited: screenshots embedded. The Roll gain is 100, but it does the same if the gain is 70. If I 'tap' the gimbal with a gain higher than 100 the gimbal oscillate more and more. If I set it at 130 (like most of you do), it become crazy.
Cedric I can't see the attachments. Can you reload them by clicking the "Upload a File" button and then doing the file Upload? Have you tried flying it? Sometimes static testing isn't the same as behavior in flight.
I edited the first post: attaching files doesn't seems to work (for me) so I embedded the screenshots (via imageshack). I tried it in the air and the results aren't good. Roll radian 'on' : vibrations Roll radian 'off' : clean (but not stabilized of course)
Can you show a photo of your gimbal to your copter setup? Something just isn't correct. The lowest roll gain on the shared setup Google Doc is 90. Perhaps you can switch the servos around and re-test?
Uploaded with ImageShack.us Uploaded with ImageShack.us I know that the gain is really low. But I don't know why. I will switch the tilt and roll servos and see what happens.
Switch done. It seems to be better. I need some test flights. But no time before friday. I'll keep you in touch.
Cedric if it still acts up try turning off the video TX. It shouldn't affect anything but might be a process of elimination point.
