regime, including wild 3D maneuvers. Its prodigious power substantially increased the thrust-to-weight ratio on our test model well beyond that of the nearest competitor and yielded more torque as well. The side-mounted carb was a breeze to tune, and the Reed Valve induction helped keep the mixture right where we set it. JR's IMZ RV-50S features a unique mounting pattern, so a special mount is required to install the RV-50S in the JR Voyager 50 or Ergo 46. The JR IMZ RV-50S offers a premium performance engine well worth every dime, and the included KSJ muffler really lets it scream. If you want to over power your .40- to .46-size heli, this beauty is the engine for you.

Engine Type: 2-Stroke
