O.S. MAX 75 AX-BE Bio Ethanol Aircraft Engine for Airplane
This is O.S. MAX 75 AX-BE Bio Ethanol Aircraft Engine w/ E4040 Muffler OS 17410, Brand New in Box
OS 75AX-BE is a high performance two stroke Bio ethanol engine designed for spot and aerobatic models.
OS Max 75AX BE is eco-friendly engine, which used OS bio-ethanol fuel. The MAX- 75AX-BE has the same mount size as 75AX. As such, the 75AX-BE can be installed in an existing 75AX powered aircraft, and even though burning Bio-Ethanol fuel, develop more power than the 75AX using conventional glow fuel. An added benefit - fuel consumption is approximately 40% less than that of the standard 75AX glow engine.. Although, with the exception of the green anodized prop drive hub, the 75AX-BE and standard 75AX have the same external appearance, the 75AX-BE cylinder head, carburetor and glowplug are completely new designs. The glowplug (BE3), in particular, utilizes a different thread size than conventional glowplugs to avoid using an incorrect plug.
Same mounting dimensions as the O.S. Max .61FX, 75AX
Crankcase and cylinder head are of aero-shape design which has the advantage of light weight and compact size.
The new 61A-BE carburetor needlevalve assembly has now been angled backward for safety.
E4040 Power Box muffler design provides more volume for increased power in a very compact shape.
Angular head design offers increased surface area for better cooling
Advanced Bi-Metallic Liner process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and makes the plating more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve for better compression and longer life.
