Review on 📡 10pcs Black Plastic Antenna Tube with Caps for FRSKY XM XM+ X4R X4RSB S6R/D Series/TF Series IPEX4 Receiver Antenna - iFlight by Viterbo Dashora

I could just glue them to the multicopter frame as a cheap way to keep your antennas under control, but I use them as a replacement for this product: https://www.amazon .com /gp/product/B01CI22YD8 (These tubes are slightly larger in diameter than those included in the kit above for a tighter fit.) They do an excellent job of keeping the antenna wires clear of the mounts and they hold up very well under normal flight conditions . They are stiff enough not to flex into the brace. They can be bent a bit if you're careful. Of course, the same stiffness that keeps them rigid and separate from their supports also makes them a little brittle, so expect them to break relatively easily in a serious crash. They are relatively cheap so make sure your expectations are realistic and you will be satisfied.
