I added wood control grips; I ended up cutting 3/4 inch off the control sticks themselves, as my hand seemed to want to grip lower than the uncut length. Any more than the 3/4 inch started to run the grip into the first bend. I secured the grips with a 8-32 countersunk screw. A right handed grip is used on the right, but a universal on the left, as a fair amount of time can be spent using either hand in the left seat.
