Huge power and performance!

In order for 90-sized machines to nail huge maneuvers and hardcore, smackdown-style 3D it's all about power, and the 105HZ-R has it in abundance. Displacement has been increased by 15%, while a huge venturi rams air into the carburetor, producing massive power. Plus, it fits in a .90-sized mounting pattern!
O.S. Two Year Limited Warranty
  • Featuring the displacement of a 1.05 in the mounting space of a .90.
  • More displacement means more power, and these engines boost displacement by 15%!
  • A huge venturi boosts output even further.
  • The machined, blue anodized heatsink head is light in weight, and cools the engine efficiently.
  • An extra feature on the 105HZ-R is the pressurized DRS (Demand Regulator System), which ensures consistent fuel flow regardless of the heli's attitude.
  • Same mounting dimensions as a .90 cu in engine
  • Machined blue anodized aluminum heatsink cylinder head
  • Velocity stack increases airflow and enhances engine performance
  • Pressurized DRS (Demand Regulator System) ensures consistent fuel flow regardless of the helicopter attitude
  • Backplate accepts the Futaba BPS-1 RPM sensor for the GY701 and CGY750 gyros
  • Ideal bore and stroke ratio for lowest vibration
