Hobbyking does have an RJX clone head though.

You have to replace the plastic radius arms on this head because the holes are too big (real RJX ones are about $2). Also with the ones I got it didn't have the 2x3.5x0.1 washers that are supposed to go between the flange bearings in the swashlocker arms. I've heard that they now come with these though. There is a video series on Youtube that covers this.

Though he claims that the head uses soft metal I have not seen this personally. I ploughed my 450 into the ground so hard that it dug a furrow and the mainshaft bent at a 45 degree angle, the battery tray broke off and the feathering shaft split in half ejecting both grips with the blades and only the pitch control arm on one blade grip bent. The grips themselves were fine. Given how cheap these heads are and that HK doesn't sell individual spares for them (only real RJX spares) it's cheaper to just buy a whole new head if you need one piece for it.
I like to use a slightly longer screw than the standard one with a nut on the other side to hold the swashlocker arms on. Also the screw that HK gives you is 2mm shorter than the screw in the real RJX head.
HK also has the genuine RJX head for much less than most other places.

One thing of interest is that the RJX clone head is
not listed in the FBL head section on HK with the real RJX heads.
