O.S. Engines R21 Hasi Tuned on-road engine
Multiple World Championship finalist, Silvio Hächler, is entering the 1/8th nitro on-road market with his own brand and the new O.S. based R21 Hasi Tuned 3.5cc engine. Made to the exact same specifications Silvio utilised in China last November where he TQ’d the SIGP race, the engine is based on the latest O.S. R21 Euro Spec variant and it is available only as combo set including the M2001SC manifold and T-2080SC exhaust pipe. The engine is professionally tuned, offering a differently timed crankshaft, modified case and sleeve. The specifications aim to increase end speed on large tracks, giving extra power over the whole RPM range. The easily recognisable engines come with a modified cooling head and they are pre-run-in in order to offer uncompromised performance on the track. The engine is available world-wide here and in Switzerland it can be ordered directly by contacting Silvio.
