Shuttle Z-TS: Pushrods/Swashplate sticking at extreme cyclic

[darren_uk]

Hi all,

I have a Shuttle Z-TS.

It's the stock set-up.

I've just been having a look at the push/pull rods and the general setup around the swashplate.

I popped off the collective from off the servo because I wanted to check to see if there was any resistance anywhere, and I just found some:

The collective moves freely up and down until I move the cyclic to one of the corners (e.g., forward-and-left, backwards-and-left, etc.). At this point the collective because stiff to move.

I popped off all of the sockets from the upper (rotating) star of the swashplate and the swashplate moves quite freely up and down the main mast at all cyclic inputs.

So the problem, I think, is something to do with the upper mechanics (the parts between the rotating star of the swashplate and the blades/flybar). Furthermore the stiffness depends only occurs at particular places as the main blades rotate.

I've not changed anything since it was setup by Dick Wallinger of Midland Helicopters, so my theory is that this is just a feature of the stock Shuttle Z-TS kit.

Colin, and other Shuttle owners out there, is this normal for the stock shuttle?

there's a lot of posts on RR about this.

The suggestion is that you should never need full corner cyclic. People put those cyclic limiters on their stick so you get the same total cyclic deflection all the way round.

I can hardly move my raptor collective at all with the cyclic in the corners.

oops - back button problem

this binding is normal at extreme swash plate deflections. This is not much of a problem though because the binding only occurs at extreme cyclic delections which are outside of the shuttles normal cyclic range. This stickiness seems to disappear after a few hours running from brand new anyway. I have been flying a new shuttle plus for a cuple of months now and have had no serious problems in this area. I wouldn't be too worried about it.
