I received an Xtreme upper bearing holder and an Xtreme flexible tail truss today. This was mainly because the tail truss in yellow was on discount and I wanted to make sure I got one of the yellow ones, before they stop selling those. I would like to keep my heli in the original look for now at least.
I have mounted the upper bearing holder. It is much more precise than the part it repaced. You can see it mounted in the picture below. I like this part very much. It even came with a bearing incuded. When I put it on my scale it displayed 0g so it can't be very heavy.
I havn't mounted the new tail yet. It is seen in the picture above. It's the tail not mounted in the picture . I shortly tried how it will fit when I mounted the upper bearing holder and it seems I will have to modify it a bit to make the upper screws fit the frame. Not a big modification though. When I put this tail on my scale it showed 13g
