I have two Futaba clone gyros that came on airframes that I purchased over the years, I use these for some of my scale helis and they work fine, never tried any 3D or anything so its up to you for what you want to use them for. I'm using one now in one of my scale helis, didn't even know it until I took it off and turned it over and seen the phillip head screws. I'm not responsible if you crash your heli either, use at your own risk
Only thing is, I'm leaving today (Sat.) for a mini vacation with my wonderful wife and will check back Sunday night or Monday, they will go to the first pm I get and then down the line from there, don't complain if your not first, please.
I can split them up if someone wants only one but I would rather ship both at the same time. They are free and won't cost you nothing.
Gone guys, they found a home..
