Video: Hobbico introduce the new O.S 105 Engines series

These are the engines that precision aerobatic and 3D heli pilots have been waiting for! In order to nail huge maneuvers and smackdown-style 3D with your 90-sized machine your engine has to have power, and both the 105HZ and 105HZ-R deliver. Displacement has been increased by 15%, while a huge venturi rams air into the carburetor, producing massive power. Plus, they fit in a .91-sized mounting pattern. 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.
