I get the idea about the weight, but how does the stand "stand" up to throwing the joystick around (ie, evading SAMs)?
I still prefer having the joystick assembly connected to the throttle for extra stability. But thanks a lot for posting this design, I was looking for a good way to set up my center mount. Does the PVC assembly "flex" in any way?
Offsetting the joystick is very easy with metalnwood's extension. Just loosen the top knob, twist the stick 15 degrees, then tighten the knob again. Much more ergonomic.
The PVC assembly is absolutely rock solid...these are the waste pipes usually buried underground carrying turd into the sewers

therefore the plastic is thick and durable...there is no flex whatsoever. These
aren't the flexible drainpipe style tubes you see carrying rainwater down from a roof. If you go into any B&Q, Homebase or Wicks DIY shop in the UK you will see these tubes in the plumbing section.
Because there is substantial weight at the bottom of the tube with nice low gravity, the joystick can be thrown all over the place without any worry of the unit even flinching. I'd say it's a lot more steady than the stock metal plate that ships with the Warthog.
