7 displacements – 14 outstanding values in flight power!

GMS offers front- and rear-mounted needle valve models of all 7 side-exhaust engines it makes, and for one very good reason: no two pilots are exactly alike. Flier A may appreciate the familiarity of the traditional front-mounted carb, while Flier B wants the added engine protection and pilot safety that a rear-mounted carb represents. But while preferences in carbs may differ, all pilots will appreciate the common quality and value that GMS engines offer.

All GMS engines are assembled from CNC-machined parts, with distortion-resistant, 1-piece cast crankcases and gold-anodized heat sink heads machined from aluminum bar stock. Other common features include dual ball bearing-supported crankshafts, 2-needle carburetors, tools, muffler gasket and 2-year warranty protection. Engines with displacements of .61 and larger are durable ringed-piston designs. All other engines offer the performance edge of true ABC construction. All (except 1.20 models) also include a bolt-through muffler with pressure tap and repositionable exhaust outlet. All require glow plug.
