Futaba trainer port

thingiverse

This is a project to create a Futaba-style trainer port plug for powering devices such as FPV monitors and Wi-Fi boosters. Two prongs from a PCB rail can fit diagonally with some straightening. The two middle pins are + and -, but verify the pinout on Google to confirm. The top middle pin is - when switched, and the bottom middle pin becomes + when the controller is activated. Best results are achieved by printing at 50mm/s and using a layer height of approximately 0.1mm. Note that this design is not polarity-proof. To ensure proper alignment, line up the notch on the outer rail with the designated notch location. Simply mark it and plug it in correctly to avoid issues. The notch made the print more challenging to achieve a clean finish.
