RJX Flybarless Head Assembly Trex 700 / .90 Size
Please disregard my negative review. For the cost, its incredible. I had less vibrations with the new heaed. At first the blade grips wouldn't turn. There was hardly any information on the two page manual that I had to download. Its pretty straight forward to put together. What messed me up was there were 4 screws for the control arms to connect to the blade grips. There was two different sized. I figured use a longer, and shorter on each one. Well the longer screw goes to far and barely hits the bearings inside which makes the blade grip not turn smooth. I changed that out for a shorter screw and its all better. It appeared the feathering shaft was too long at first but its not, its just really close to being too long. So far so good.Move on to something other than this? The feathering shaft is too short. When you put everything together properly according to the manual which you have to find somewhere else, the shaft isn't long enough. The thrust bearings stick out past the shaft. When you install the shaft bolt with washer, the washer hits the thrust bearing instead of meeting the feathering shaft.
I'm not an expert, but I can't tighten the shaft bolts. When I do, it compresses everything since its not hitting the shaft, and the blade holders can't move smooth. Just move on past this. Do not purchase it. I just wasted my money, when I should have gone with a tried and true KDE.Brilliant quality will be using it on Raptor 60 V2I have this head its monted on a Hirobo Freya 90,very nice looking,works great,Im very happy with it exept I have a bit of chrome peeling off,might be from the cold weather i have been flying off lately but still happy with it.thx HKOriginal high-quality RJX head!

I bought a helicopter Chaos 700E. The quality is good, but I would like to see the availability of spare parts for this rotor. 600 helicopter spare parts for the rotors have, and for a 700 class helicopter there.
