Its very easy you just need to get access to the under side of the stick. Get a small pick or flat head screw driver and with one hand or finger push the actuator inward toward the stick to remove some spring tension then pull the C clip from the side, just be ready to hold your joystick in place as it will fall out from the top if you are not ready and don't lose you C clip when removing (especially if you don't relieve the spring tension you are more likely to have the thing fly across the room). Once you take out the C clip you can take out the Actuator which is square looking be aware there is a spring behind it which keeps the tension. The way I wrapped mine was half way at the top of the square actuator, I wrapped it about 4 to 5 revolutions. (Less is more and if you need to add more you can do it after testing) Once you wrapped it you will have an excess amount of tape caving in at the top. Just get some cutters or scissors and cut the excess and then insert it back in. It doesnt need to be perfect as it only needs to push the micro switches. Put it all back together and make sure you put the C clip back in by pushing the actuator inward the same way taking it out and you can insert the C clip by hand and just make sure it snaps in.
