rgr, feels like it has it's own components either way it performs great.
The CH sticks don't use a ball joint system but a format more akin to what you find on an aircraft R/C system just scaled up. This is especially noticeable when you take them apart and inspect from underneath and explains the effectiveness of the springs without them needing to be too strong. The aileron and elevator channels are well separated. That's what I noticed the most when I got mine. The potentiometers are also considerably larger than the tiny little short lived cheapo parts you find in lesser sticks, this can account for the longevity that is commonly reported.
I also have the notchiness in the pedals. I figured something got into them.
This can happen. They are basically a pair of linked roller skates than run in their own alleys. If you have a nothcy feeling away from the centre then suspect a foreign object in the tracks and consider a strip down clean. I think I uploaded some pictures of the internals somewhere abouts, when Pervert was having his wiring troubles. The notchiness around the centre is inherent to the design. I considered a modification but am too busy atm.
What don't you like? I find it to be a great fit, but I probably have OJ-sized hands...
I understand the layout of the Fighterstick was loosely based on the joystick handle of the F-16, a design which was intended to provide a high and a low grip position according to what the pilot was doing. By making the 8-way hat switch the top right hat, I find I cannot reach it and use the hand rest at the same time. I have to hang my index finger on the top and pull the trigger with this: .|.. finger

which isn't so good for the hand after an hour. There is a mod to make one of the lower hats the eight way I know and some people make a pad to raise the hand rest.
