Dual Throttle For Flysky FS-I6X (Boat Throttle Style)

Uses the electronics from the stock throttle/yaw stick and turns it into a dual throttle set up. I made it because I am building an RC boat but there are no controllers on the market (as far as I can see) that offer dual throttles like this. Its primary use is for RC boats with 2 propellers. This also uses metal springs for the centring on the sticks, but I plan on making some 3D printable springs for it too. It uses the screws from the old stick assembly, but you will need 2 extra 2mm screws to hold the handles on the sticks. *Note : It requires you to cut the back shell off because it doesn't have enough clearance. I made it as compact as I can but its still an issue. If you want to, feel free to try to make my design more compact.
