These are a great upgrade for the HK-500 GT, they remove a lot of slop and help with tracking. The plastic arms that come with the GT cause problems under load.

The bearings were even lined up correctly, I was able to tighten the arms down fully without binding. Just make sure to remember the brass washer between the bearing and see-saw. Oh and of course you still have to loctite it.

There is a problem with the bearings in these as they cannot be tightened properly to the flybar holder without binding up, at least not using the washers provided. There is a brass spacer between the 2 bearings in the stock plastic flybar arm. I tried using this as a washer between the bearing of the metal flybar arm and the flybar holder and could tighten the screws without binding.I bought these metal flybar arms to improve blade tracking. When I installed them first I didnt tighten the screw fully to prevent binding as suggested by some people. I still had blade tracking issues however because not tightening the screws fully caused some slop. when I used the brass spacer and tightened the screws fully, my blade tracking was fine. The same problem exists with the metal washout arms when they are fully tightened. I could not use the brass spacer on these because it changes the position of the arms so that you cant connect the swashplate ball links. I thought that the cover part of the bearing may be protruding too much in relation to the inner race rim so I tried pushing it in gently with a small screw driver. I think it made an improvement as I could then tighten the srews a bit more although not fully. So a good bit of hassle before I got them installed satisfactorily. It would probably be easier to get align plastic flybar arms instead as these will also cure tracking iss

The stock plastic Control arms on the HK500GT must be replaced with these to remove blade tracking issues and make the helicopter actually flyable. These are the same Titanium anodized colour as the stock metal finish.
