O.S. Engine Limited Edition Gold 105HZ-R Heli Engine

From O.S. Engine:

Limited Edition – Only 200 in the world!

O.S. Engines truly are the gold-standard for RC models and we’re proving it with this special, 80th anniversary, gold edition engine! This special, super-limited edition 105HZ-R brings you the same 3D power as the original but with a super-sleek gold-anodized carb stack and cylinder head and a lethal-look black anodized crankcase. Plus, you get the efficiency and awesome throaty roar of an included pipe exhaust.

More displacement means more power, and these engines boost displacement by 15%!
A huge venturi boosts output even further.
The machined, gold-plated heatsink head is light in weight, and cools the engine efficiently.
An extra feature on the 105HZ-R is the DRS (Demand Regulator System), which ensures consistent fuel flow regardless of the heli’s attitude.
