We are introducing new tuning control stick tops with aluminium anodized body and CNC-machined centre section for KAVAN V20 and V15 transmitters or FrSky alternatives. They have a built-in two or three position switch and push button. They will allow precise and easy switching of flight modes, on/off mixes or even landing gear extension/retraction without having to drop the stick and "fumble" for the right switch.
