Bench trial for 2.4ghz wireless steering wheel button system

bench test for a 2.4ghz 6 channel control system. system is indented to go onto a steering wheel allowing for control of 6 channels such as indicators, lights, horn and maybe a flatshifter.
as seen in the video there is a delay of when the transmitter stops, meaning a delay from when the switch is turned off. while this is ok for non time critical items such as lights on and off. it may cause issues with say the horn and the flat shifter. especially with the flat shifter where you may want really quick movement so you can modulate it.
