O.S. Engines Gasoline Engine GT22 (OS38200) (OS38200)
O.S. Engines is a leading manufacturer of single- and multi-cylinder model aircraft engines ranging from small two-stroke to "giant-scale" four-stroke radial engines. Japanese model engine manufacturer that produces very affordable and yet easy to use model engines which won acclaim for their performance and durability.

The OS Engine GT22 best fit models designed for 15cc 2-stroke or 20cc 4-stroke glow engines. Provides pilots with its reliability and durability, simple and inexpensive operation, easy adjustment, high efficiency and high performance. It creates more power and thus comes with the ability to turn larger diameter propellers than competing engines of this class, making it the first choice for pilots with the highest expectations.

An investment in O.S. gasoline power quickly pays for itself in fast starts, higher power and more flights from your fuel budget.

GT22 High performance, hand-crafted, quality inspected O.S. engine.
Uses beam mounting, unlike most other gasoline engines, for easy installation in planes designed for glow power.
Pitts style muffler has been reinforced at seams, bends and mounting bolt locations for maximum strength.
The IG-02 electronic ignition system handles 4-6 cell NiCd/NiMH or 2-cell LiPo/LiFe batteries.
Rear-mounted Walbro carburetor is custom-designed for the GT22 — a choke rod guide has also been integrated into the crankcase for effortless setup.
260 ml tank is sufficient for 11-12 minutes of aerobatic flying with a reserve
Comes with single prop locking nut.

The fuel tank and all fuel lines must be for gasoline (Tygon).

Japanese model engine manufacturer that produces very affordable and yet easy to use model engines which won acclaim for their performance and durability.

Features:
The O.S. GT120T is a 120cc flat twin petrol engine ideally suited to large aerobatic aircraft where only the best will do. The impressive 10ps (9.88hp) power output is perfect to power a 100" class aerobatic aircraft as used in 3D and IMAC competitions across the world. The crankcase is precision made from aluminium using the latest machining technology OS have on offer. The HS-324A carburetor was designed to produce a special emphasis on throttle response. The GT120T includes a newly designed lightweight ignition unit called the IG-10 to provide a reliable and strong 'spark' with easy start ignition timing and protection against backwards running. To make installation simple the mounting dimensions match most popular existing 120cc twin petrol engines.

O.S. Engines is a leading manufacturer of single- and multi-cylinder model aircraft engines ranging from small two-stroke to "giant-scale" four-stroke radial engines. Japanese model engine manufacturer that produces very affordable and yet easy to use engines which won acclaim for their performance and durability.

MAX 105HZ-R with Powerboost Pipe 105 (OS72146000)

The biggest, pure helicopter engine that OS have ever made delivers the levels of torque and power demanded by top fliers for both '3D' and sport applications. The 15% increase in capacity offers a big increase over the .91 class engines yet still fits in mounts designed for that class.

Features:
Easy carburetor adjustment that stays in tune
More torque in the mid range for 3D
Velocity stack on carburetor sucks cool, undisturbed air from the fan flow
Power output of a 105HZ with 15% nitro is similar to a power of 91HZ with 30% nitro

The latest DRS system (Demand Regulator System) uses a crankcase pressure tap-off to pressurize the fuel tank via a one-way valve. The pressurized fuel is then carefully regulated at the carburetor to provide the optimum mixture no matter what demands are placed on it. This is done by using the negative pressure in the carburetor Venturi as part of the regulation system.

The carburetor itself has three mixture controls for low/mid and high speed settings. Once set for the fuel demands of your model/type of fuel and muffler, there is rarely any need to change those settings again.

The main mechanics of the engine itself are the same as with the regular MAX 105HZ engine.
