Simple Nerf Gun for Rival Ammunition

cults3d

My version of a simple Nerf gun to use Rival ammunitions e cartridge, everything is 3D printed, the motors, esc and 5v regulator are form old drone racing parts, the trigger is from a 3d printer end stop and the servo tester and GM12-N20 were bought from amazon. Wiring is very simple, the 2 bl motor must turn in opposite way, the signal wire connect to the servo tester, the esc and 5v regulator connect directly to the battery the 5V is only to power the servo tester, the GN12-N20 motor and gearbox connect the positive to the battery and the negative to the switch and from the switch to the battery. It possible to s shoot single ball burst or full auto. The servo tester control the start of the 2 esc and speed. (the gun can handle 3s with no problem, a 3S 800mha is perfect)
