The Brian Schapiro signature seriesJethro34FR has been in development for over eight years. The heart of the engine is a full circle +2mm stroker crankshaft, forged connecting rod and billet aluminum reed case. This combination offers maximum performance with the ultimate in durability.
It started with pushing the limits with speed runs with an HPI Baja. I needed an engine that had great bottom end and mid range torque that was able to scream with big RPM on top. We were the first large scale car to run 95+mph with a motor under 35cc. At the same time I started racing a 4wd Losi. I needed the same results from my engine. OBR and myself have thousands of hours into product development on the track and on the dyno. Numerous podium finishes, race wins and National championships. TheJethro34FR edition signature series does it all very well. Whether you run a Losi, Vekta or Baja you can expect massive bottom end torque that will throw gobs of earth and dirt while on its way to peak RPM. The combination of this engine matched with the 1242A carburetor OBR pipe is sure to wake up any large scale rc. Whether you are racing for points and time or bashing in the park... theJethroedition 34FR gets the job done very well. For years theJethroedition has been held exclusively for team drivers. The Pre-eminence, Excellence, Abundance and Overflowing power is now available to everyone.
