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?
