Title: VEZ aileron control slop
Post by: mattstecher on July 25, 2013, 11:24:08 PM
I am putting the aileron controls back together on my Vari and am seeing quite a bit of slop. About 1/4 inch side to side at the FW where the pushrods attach to the CS124 fitting and the pilots stick is not moving. It seems to be aft of the passenger bearing and in front of the FW which seems to point me to the universal joint. How do I test these? Or should I be looking at something else. The plans don't seem to give me any guidance on what tolerance I need to meet here.
Thanks folks,

In the area behind the passenger stick there should be zero slop/movement. Either the bolts are badly installed with tube bolt holes that are too big or the bolts are loose or the U/J is bad.

Rutan's stick design where the stick cantilevers to one side of the horizontal tube is simple but in my opinion poor and it is very hard to minimise slop while maintaining sufficient freedom to move.

The Cozy front & rear stick design arrangement is a much better design as it straddles the horizontal tube so play is minimised and is better bushed too.

ie parts CZSA and CZSA-2

I have these installed front & rear in my VariEze (with a single rod direct to the elevator ie eliminating the cumbersome & heavy forward  belcrank) and I have zero slop from front stick to aileron.
