This engine is a replica of the original engine Letmo md-2.5 of M. Pfeffer from Brno, Czech Rep. The Letmo MD-2.5 rose from the Letmo MD-3 engine to compete against. The design of the engine is a typical first postwar, long stroke, self ignition, plain bearing, piston controlled combustion, "T" type side scavenging, three axial attachment lug type crankcase. The new replica is practically the same engine as the original M Pfeffer's Letmo except for following: heat treated crankshaft (the original was from mild steel) and cylinder liner (the new is nitro carburized, the original was standard hardened tool steel). The other change is the new shape of the window in liner wall. The reason to this is a better starting and higher power. These engines are produced on modern CNC machines like any standard MP JET engines. These engines are produced in a 1000 pieces limited series, each engine has his serial number (on the rear side of the crankcase). Engine spare parts parts are currently available, the replacement of crankcase will only be done by an exchange of the old damaged one.
