OS Max OS Max 18750 105HZ-R DRS 1.05 Helicopter Engine

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.
