This is the Jammin Products JPX.21 Plus off-road buggy engine by OFNA. Jammin Jay himself did the R&D on this engines and paid special attention to the details that are so important for off-road R/C racing. Such as durability, ease of tuning, and driveability. Tweaks to the materials, crank timing, and tolerances all played a part in getting the engine to the high performance edge that Jammin Jay requires. The OFNA Jammin JPX.21 Plus engine delivers excellent bottom end power with great top end run out and includes a Turbo Plug type head. While the Jammin JPX.21 Plus is tuned for buggies, testing proved it to be more than capable in the truggy class. Turbo Glow plug included. Made in Italy.
These engines run best with a medium hot Turbo plug, such as the OFN51006 plug, or an O.S. P4 plug. This engine comes with an OFN51006 medium glow plug in the box. You may wish to run a OFN51005 glow plug which is hotter to make the idle more consistent, but the colder plug will produce a little more overall power.
