Beach RC says.... The Revolution Design Racing Products Aluminum Dial and Nut Set for the popular Sanwa M17 high-end radio is a quick and easy way to personalize your transmitter to the maximum. The dials and hoop retaining nut are machined from high-quality aluminum and of a serrated design for better gripping and improved haptics. The Dial and Nut Set is available in seven different colors including black, blue, light blue, green, gold, orange and red while machined silver color edge details and laser-engraved logos make the parts stand out. The accessories are a direct fit on the M17 radio and can be combined with our new Sanwa M17/MT-44 RDRP0500 Aluminum Steering Wheel.
