3D printed adapter for B1 transmitters.
- Screw a metric 3mm (M3) metal screw to the holes and remove before the first use.
- Remove the bottom hex nuts of your transmitters,
- Loosen(half turn) the hex spacers between two PCB layers, so the screws may turn freely.
- Place the transmitter to the adapter and tighten the screws.
