28XZ Truggy Engine O.S. Engine  [OSMG2074]

With input from top truggy drivers, O.S. is marketing and advertising top motor among these hybrid hot rods! The 28XZ creates more low-end torque, providing the rpm/torque safety that weightier truggies require. The end result is energy that??s acutely smooth, for truggies more drivable than previously thought feasible!

Greater mind supports ac, which is a 2-piece construction with internal head key.
A sealed front bearing and superior interior bearing are part of the unique crankcase design.
The superior con pole features oiled bushings.
Three needles enhance fine-tuning regarding 21J slide-valve carbohydrate.
Includes a high-performance P3 hot turbo plug.
The Mark Pavidas Edition Tuned pipeline (OSMG2969) could be the perfect accessory the 28TZ; flywheel sets are required (OSMG2648 for Mugen, OSMG2649 for Kyosho, both available independently) for a number of truggy models.
