I bought this off a fellow RR memeber, but have since decided to go the multirotor direction.. so here it back up for sale.. the gyro setup is very cool, but I'm leaving my 700 as a 3D machine for now:
Helicam Solutions Photo mount that has been optimized/modified for smooth aerial video With Kenyon KS-2 gyro. Kenyon KS-2 has a deans plug on it currently.
I bought it previously owned, but it works great. It's a bit too heavy for my multirotor, but some of you have bigger ones out there. I've also lifted it no problem with my Trex 700.
$650 shipped within continental US.
