No matter what radio system and receiver you're running, you need somewhere to put your antennas. You could tape them to the frame, but that could introduce shadowing issues depending on the orientation of the helicopter. With this boom-mounted antenna guide you can keep your antennas at the proper 90 degree angle far away from the RF-shielding carbon frame.
This product includes:
1 x Antenna Guide for T-REX 470L (PLA Plastic)
2 x M2x14 Screws
Also works with any other helicopter equipped with a 13.5-14mm tail boom.
This product is made to order, so processing time before shipping can be as high as 1 week.
