Orcan RSR-MH 2.1cc nitro on-road engine


Orcan have introduced the new RSR-MH 2.1cc nitro on-road engine for 1/10 touring cars. Based on the successful RSR3-MH Sound of Racing model, the 2.11cc RSR-MH has been upgraded and refined for 2018. Changes to the 2018 RSR-MH versus the RSR3-MH model from 2017 include:

  • The RSR-MH comes complete with a shim located under the sleeve that can be added or removed to change the timing and thus the performance characteristics. With the shim fitted, the RSR-MH´s timing is set up exactly like the 2017 RSR3-MH, making it perfect for medium-sized and large tracks.
  • Removing the shim from under the sleeve changes the timing to deliver outstanding drivability and extra torque. This also reduces fuel consumption, restricts the maximum rpm and thus limits top speed.
  • As on previous models, the carburettor comes complete with insulating bushing. In addition, modified air intake characteristics deliver lightning fast responses to acceleration commands.
  • The distinctive outer of the new motor has an aluminium-coloured cooling head engraved in grey with the insignia ORCAN RSR-MH.
