This little ring can help you adjust the resistance of your remote control sticks by adding tiny rubber bands on the grooves. You can add probably up to 5 bands for each direction and you will have to use some double sided tape to mount it on the controller!
Installation takes about 2 minutes and no technical skills required at all.
This can help you get better shots by moving the sticks very steady and slow even if your fingers get a little "shaky" when flying far or risky or just in cold weather.
Package Includes: 1 Stick Stopper Ring.
If you want to 2 pieces, please buy 2 rings.
