In this video, we build an Arduino-based Grip-style (Pistol-grip) Radio Transmitter for controlling custom RC vehicles.

This home-built RC transmitter is ideal to make if you're looking to use up some spare components and your 3D printer. A great DIY alternative for controlling Arduino-based DIY RC vehicles with lots of flexibility in programming and peripheral options.
