Just had to tell all of you about this $59.95 three axis gimbal deal on EBay:
This seemed like a great deal and looks to be identical to DYS Gimbal on Hobbyking which is $200.00.
I got one and quality appears excellent though I haven't tried to use it yet (I will probably get another.)
I'm planning on converting to a Storm 32 for a laser rangefinder scanner.
Apparently DSLRPros has moved on and is wholesaling them out.
I get nothing from anybody for this, but if you want a real 3 axis gimbal, this is the best deal you'll ever see.
Heres a link to the manual for the DYS: http://www.getfpv.com/media/wysiwyg/documentation/3AxisbrushlessGimbalManual.pdf
Heres a link to the Basecam (Alexmos) Home page: http://www.basecamelectronics.com/
And a link to download the appropriate 8bit Alexmos Gui: http://www.basecamelectronics.com/files/SimpleBGC_GUI_2_40b7.zip
And a link to download the Alexmos manual PDF file: http://www.basecamelectronics.com/files/v10/SimpleBGC_manual_2_4_eng.pdf
(This does include the Alexmos 3rd axis expansion board.
Best regards to you all,
Gary

Just to let you guys know, more of these will be available today!
Missed it.

Would love to see some sample footage from one of these.
Thanks Gary for posting! I managed to get one as well. Always interested in a bargin! ;-)
Hope any of you who wanted one of these got one, apparently they sold out pretty fast after I posted it.
Probably worth checking DSLRPros Wholesale site on Ebay every once in a while, they have quite a bit of stuff, but none (now at least) as good a deal as this was.
@ Thorsten, I will publish more about the laser scanner in furture Blogs and on the Vision Systems page of my Drones Are Fun web site.

Brushless Gimbal resolution is limited by several factors, but primarily by the accuracy of the pole balancing circuitry, the power applied to the coils, the constant and dynamic force reguired (perfect balance), the mechanical play in the Gimbal and the resolution of the controlling PWM.
Typically they can stabilize better than they point, because the transmitter / receiver PWM is of more limited resolution and because with a balanced camera very little force needs to be applied to provide stabilization.
(Basically you are holding the camera still while allowing the airframe to move around it).
Well made bigger diameter motors with more poles will generally allow higher resolution movement and better support long lens's.
On a DSLR sized rig I have seen 60x zoom German You tube video that was completely stable, that is probably less likely on the smaller ones with less poles.
It is possible that the new oversized frame digital stabilization methods used by some of the newer cameras can actually be used to good benefit in this as well although they seem to do much better on pitch and yaw than on roll (for obvious reasons).
Best Regards,
Gary
...anyway, I am more interested in your "laser rangefinder scanner prototype". Sounds interesting! Any details so far?
Best regards,
Thorsten
Too late: "This listing has ended."
I'd like to know this too - i use a 30x zoom on a SAR rig, and can only get to 12-15x zoom before it starts bouncing; I', pretty sure it's a resolution issue at the gimbal - it's always the same, regardless of what you do with PID.
