Is it possible to rewire the RX-18 Hl tanks to fire the airsoft cannon using the K switch instead of the left joystick? Also I was hoping to upgrade my airsoft BB shooters to get a little more power out of them, before the Oct 23rd tank meet in Ft Erie. I notice the airsoft motor has a small capacitor soldered across the terminals, is this to stop the inadvertent reversing of the motor?
