O.S Max 105HZ Helicopter Engine

This is the engine 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 the 105HZ has 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.
