O.S. SPEED .21 XZ-B SPEC. III
"O.S. have released some info about the successor of the O.S. Speed 21XZ-B spec.II, the new Speed 21XZ-B spec. III at the Shizuoka hobby show. The Speed 21XZ-B spec. III features a newly designed crankcase and piston and cylinder and its displacement still remains at 3.49 cc (and not as 3.46cc like the Speed B2101). The engine head is 5mm lower than spec.II for lower gravity. Last improvement, the 3-port exhaust makes air flow effective after combustion. It will be available alone or as a combo with the T-2060SC (EFRA2042) tuned pipe. Shipment start in August."
