I bought another set of these and more changes have been made since I purchased just a couple weeks before that! It still comes with the flap damper, feathering shaft, bearings and screws but now the grips and head have the "RJX" logo painted on in light gray. The ball link arms on the grips are also now chrome color instead of black which I prefer. It would be nice if these changes were documented as for some people building scale helis, this may be an issue. I still find the flap dampers too stiff. I recommend using the Align ones. With the RJX flap damper, the grips don't move freely enough. Aside from that, I'm continued to be impressed by RJX. I love their products and hope to see more in the future. The head looks great and the quality is nice. I'm replacing my align heads with RJX now.

Nice matte black finish. My kit came complete with bearings, feathering shaft, flap dampers, washers, etc. However, my complaint is once everything is assembled, one grip rotates significantly tighter than the other. I'm not happy with how much resistance one of the grips has. I'm not sure if the bearing is tight or it's something else, but it's enough that it bothers me. Under load with the arms naturally pulling outward while the blades are spinning, the grips free up a bit, but even then, the one grip is still quite a bit tighter. I'm not completely satisfied. The price is decent, but this issue should be addressed. If not for that one issue, it would make this head assembly an amazing deal.

j'ai reu ce qu'il y a sur la photo avec en plus l'axe des pied de pale. il faut donc garder l'axe principal, les biellettes et le plateau de l'ancienne tete. Trs bonne tte, mont sur un HK500GT, ca inspire confiance et il n'a a pas un poil de jeu. Le rglage n'en est que plus facile (pas du tout de tracking lors du premier vol). A voir dans le temps, je n'ai fait que 2 vols cool pour l'instant.

i just received and assembled this. EVERYTHING is included, including spindle shaft and spacers for the blade holder. no need to get spacers or spindle shaft from the stock flybarred head on the trex500. very nicely made and quality looks to be good. very good finish. only downside is there were no manuals included. build is straightforward so manual is of little use. two thumbs up!

I'm very impress with the quality and looks of this kit. The kit comes with everything other then linkages which I was surprised about.



In my kit I had the following

Feathering Shaft & bolts

Hard quality dampeners (Black)

Thrust bearings

Smooth Bearings in Main grips



And everything in the product pics

Grips are smooth but included fetahering shaft isn't as good as Align or Tarot. Doesn't come with a plastic feathering shaft sleeve either but this is optional. One of the screw in link balls for the pitch control arms was longer than the other. I replaced with swashplate link balls, there are slightly the wrong length but will work till I can get correct replacements.
