OS Max-105HZ Heli Engine 18700

Enjoy huge power and performance with the compact 105HZ!
The OS Max 105HZ 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 105HZ 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.
