RC antenna Mast for T4 Quadcopter

thingiverse

You'll Need a Quick and Simple Antenna Mast for Your RC Radio Receiver. Follow These Instructions: First, check if your mast needs an additional "mouse ear" at the end to prevent it from curling up due to the print bed's shape. I accidentally let mine curl, but it turned out looking pretty cool so I just went with it. The mast mounts directly onto the square opening found on the top plate, situated near the front side.
