Hi All

I am new to helicopters and am starting out with the Blade CX. So far it is great, I can hover and fly pretty well as long as it is nose out.
However, I did break the lower roter head and needed to replace it. I have a few questions regarding it and the associated pieces.

1. There does not seem to be any flat spot or hole in the outer roter shaft for attaching the lower roter head with the 4 screws. Is this just a tighten as much as you can piece? At a certain point the screws just spin but they does seem to prevent the head from moving.

2. How do you know what height on the shaft to position the lower roter head? I positioned it so the lower swashplate was about level and there was a small gap between it and the outer shaft retaining collar.

3. Should the lower roter head be able to move vertically? I know this is a very basic question, but I want to make sure I do this correctly. Right now mine is tight on the shaft and cannot move vertically.

4. This is a big one. I cannot get the lower swash plate to stay flush with the upper swash plate. My first question is should it stay flush? My guess is yes, and based on the pictures I took prior to replacing the part, that was the case. After I replaced the lower roter head, everything was fine for about a day. Now, as soon as I apply a little throttle and then move the right stick, I can see the lower swash plate fall down and rest on the outer shaft retaining collar. Once this happens, I have no right stick control.

What normally keeps the lower swashplate snug against the upper one?

Any help any of the experts on this forum can give me is appreciated.

Thanks
