I have an X-Cell Pro II with a split-gear constant drive auto hub similiar to part #0866.Mine has gold aluminum parts and the gears are black.The difference being the gears on mine look like they are from a normal black gear #0549-95 that has had the tail drive center section machined out leaving the outer main gear section as a ring.The center tail drive section is held onto a gold aluminum center hub by six machine screws that pass through into a aluminum disk.The out main gear ring section is held by 10 machine screws to a large gold aluminum lower disk.The lower aliminum disk has another aluminum hub bolted with 6 machine screws to it with a ball bearing at each end inside of it and a one way bearing between them.I have pictures but do not have the faintest clue how to include some with this post. I am hoping someone can help me figure out who made this auto hub.I was told it is a Miniature Aircraft part but I have not part # so finding info is just about impossible.The reason I would like to know more about it is it has been locking up from time to time and seeing as I have no instructions for it I am not really sure if it has been set up right.Yes I have thought about buying the newer unit #0866 but I would still like to find out who made this one and more about it.

That's a first generation MA constant drive that was out for just a season or so prior to the release of the current system. Actually, there was a pretty good lag between the time it was discontinued and when the split gear system appeared. Since parts haven't been around for that unit for years (unless you'd care to machine the gears yourself from old black gears and source the bearing(s) ), you ought to go shopping for a split gear system.

Thanks for the reply. You would not know where I could possibly find instructions for this unit and what year it appeared or even the part number for it. My Pro has the Heavy Duty front T/Rotor transmission tune-up kit #0832.The instructions for this kit say it cannot be used with the #0550 split gear constant tail rotor drive.I am hoping the one I was refering to in my original post is not the #0550 one. The instructions for the front tail rotor transmission upgrade say the #0550 split gear unit will not work with it without extensive modifications and I have had no problems fitting the one I have.It was actually already on the heli when I bought it and nothing has been modified.I also have the original auto hub and slipper clutch #0551 or #0552 that came on the Pro.
I plan on getting the newer split gear set up for my Pro II but I was hoping to put this unit on my X-Cell 40 that has a 50 in it with a longer tail boom and 600mm blades.I have a number of the 9 to1 black gears and was going to machine a few to fit the older split gear auto unit.At the moment the older split gear hub is set up with a 9.5 to 1 ratio as that was what it came with.So far it has worked good even though it has locked up from time to time.I have taken it apart and cleaned it and used a little light oil on it but for some reason it still locks up once an awhile.I am not sure if there was a problem with these hubs as this one has only about 40 flights on it and the locking up has happened since day one.
