The brand of multiple IFMAR world champion Marc Rheinard, MR33, released a great new product to check the final drive ratio (FDR) of brushless powered RC cars. The FDR Checker will be a very helpful tool for all technical inspections at club races and bigger racing series. The ETS will use the MR33 FDR Checker in the future as well.
The FDR Checker is made from high quality materials and components and will be a reliable tool for many, many years. The device comes in a hardcase bag and includes a motor sensor cable, a magnetic USB power cable, and quick reference manual. The MR33 FDR Checker is available at ToniSport!
