Aluminum radio plate mounts allow more solid radio plate mounting, and minimize the chance of stripped threads. Newly-updated alu appears allow small throttle servo become mounted underneath the radio dish, and also the center gear to be more precisely tensioned. The left alu stand allows more tighter belt stress adjustment. Ultra-strong construction provides very long life and durability in perhaps the many extreme racing conditions. CNC-machined from premium Swiss 7075 T6 aluminum. Pair of 2 pieces (left & right).
