RM2 Engine Tuning Screwdriver – Red

A tuning screwdriver is a racers best friend at the nitro events. A quality flat head design, lengthy tip and accurate handle for making fine adjustments is critical. The RM2 tuning screwdriver by JConcepts is the ticket for the precision minded racer.

The aluminum handle is custom machined, red anodized and spiced with 2nd operation silver highlighting to bring some luster to the pit area. The top of the wrench is capped with injection molded JC plug and the handle itself is topped off with laser etched JConcepts logo for authenticity.

The tip of any wrench is mandatory for function and control. The spring steel flat blade screwdriver is made of multiple pieces and pre-assembled. The tip slides into a sleeve which is secured with beefy set screw located on the adapter itself. The tip is precision ground for shape, angle, and thickness for the all-important engagement into carburetor adjustment screws.

The entire steel tip assembly slides into the handle and snaps into place courtesy of the magnet located in the handle. The magnet has enough holding power to maintain position during use and the occasional drop and pop during normal usage. When it is time to pack-up the pits or drop the footprint, simply pull the tip assembly out and place alongside the handle in the toolbox or bag.
