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.
