This extender arm is specifically designed to position your receiver (RX) antennas away from the drone's frame, a crucial step for optimizing signal reception and reducing interference caused by carbon and onboard electronics. It is particularly suitable for 18mm RX antennas such as TBS Crossfire or ELRS.
The triangular base provides stable mounting on your FPV frame, while the end with the hole is designed to securely house the antenna. Correct antenna placement is fundamental for the range and reliability of your radio link.
Features:
Extends RX antennas away from the frame for improved reception.
Designed for 18mm RX antennas (e.g., Crossfire, ELRS).
Robust triangular base for secure attachment.
Easy to print and install.
⚙️ Recommended Print Settings:
Material: TPU (Shore 95A or 98A). For this type of arm, TPU is highly recommended. It offers the necessary flexibility to absorb impacts and protect the antenna in a crash, unlike rigid materials that would break.
Layer Height: 0.2mm
Infill: 30-50%. Higher infill can provide more stiffness to the arm while maintaining TPU's elasticity.
Walls/Perimeters: 3-4 for good structural strength.
Supports: Supports may be needed under the end part with the hole, depending on the print orientation.
Orientation: Print the part flat on the build plate, as shown in the image, for maximum strength along its length.
