I have several quad's hexa's etc, which includes a Phantom P2 with H3-3D gimbal. I am so impressed with the stability of the gimbal and the smoothness of the tilt function (once you turn the gain way down to 2 or 3). I was so impressed that i went out and bought a standard version H3-3D for my Action Drone AD-1 spider quad (which already had a great all carbon gimbal... but only 2D). I spent a few hours making a carbon mounting system for it. Got everything set up and went to adjust the tilt gain in the Assistant software - LOWERING THE GAIN IS CRITICAL FOR SMOOTH TILT FUNCTION. Much to my disbelief there is NO WAY to adust the tilt gain in the Naza M assistant software like there is in the Phantom Assistant software. BOGUS! I am pretty pissed :evil: .... I did some searching and indeed this is a HUGE OVESIGHT on the part of DJI. Here is the thread on the DJI forum: http://forum.dji.com/forum.php?mod=viewthread&tid=60 I am most likely going to return this gimbal unless DJI addresses the issue - unfortunate, this was an awesome installation on my spider quad...

AARGH!!!!!!!
