O.S. Max-105HZ
105HZ & 105HZ-R Heli Engines
Enjoy huge power and performance with the compact 105HZ and 105HZ-R!

These are the engines that precision aerobatic and 3D heli pilots have been waiting for! In order for 90-sized machines to nail huge maneuvers and hardcore, smackdown-style 3D it's all about power, and both the 105HZ and 105HZ-R have it in abundance. Displacement has been increased by 15%, while a huge venturi rams air into the carburetor, producing massive power. Plus, they fit in a .90-sized mounting pattern.

    * 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.
