Prolix RC’s sidewall doctor is a high torque, full metal gear system for gluing the sidewalls of on-road RC tyres. The device can spin very slowly and the gear reduction has enough torque to keep spinning even when the CA tip strikes the tyre. Available are four different size circle adaptors to help mark out and precisely glue the tyres to the preferred glue height and they are available in three separate packages. The high grip option contains 59 and 60mm disks, standard includes 59.5 and 58.5mm disks, and complete option has all four. Each also comes with a paint marker and wheel adapters for Formula and 1/12th scale cars are available separately.
