If your joystick is our of warranty you could drill holes through the bottom of the thing and bolt the joystick to the brackets.Gosh aye. The weak points are the chair or the Velcro I'd imagine though.
The brackets come with a spanner and Allen key so your strength determines how tight it all is. I used a drill with an Allen key bit to tighten the bracket to the chair and it didn't move last night after a good session. The x and y are adjustable via the spanner. The locking nut will resist a lot of torque once you have it in place.How stable are they? This looks good but it would irritate me if there was any give in the movement or woggling around.
Cheapest I have managed to find them is at cpc (farnell) .Wow nice but where did you get pole mounting VESA brackets for a tenner? cheapest I've found on ebay is £25 each
I'm not using the keyboard during flight but I see what you mean. If its needed during flight, its only a shuffle forward to reach it (and the beer) or even have it in my lap.Very clever... But how do you reach your keyboard now (Or more importantly the beer on your desk)? Surely those controllers are in the way?
