At the moment, I'm retrofitting a Taigen Motherboard with Mako into a JJRC tanker truck to serve as a moving target. My mako works with both Taigen apples and wiring. The 3D printed Tamiya bases that I have, (ordered from RCTankelectronics, or Ozarmour), are pinned the same as a Taigen and fit on the mako in the same slot. My problem: The boards have to decide they want to receive hits: The LED will light up every shot, but the motherboard/speaker only explodes when it wants to. Doesn't matter which apple is attached.
