Coming from the Hasi Tuned brand of multi-time World Championship finalist, Silvio Hächler is a new O.S. R2104 based nitro on-road engine. The power plant is made to the exact same specifications as Silvio's race engines and professionally tuned, offering a differently timed crankshaft, a 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 instant and exceptional performance on the track.
