As RC airplane hobbyists, I think this is good news of September. Yup, the new China RC hobby factory AGM has just launched their second new product. According to the news from the company, the newest engine will be available in the market is a twin cylinder gas engine named AGM-60.
Most people know that the AGM-30 was the first engine sell at affordable price by the company. The AGM-30 released in July 2013, packed a single cylinder engine with 3.7hp/8500rpm output power. But do you know what's the next featured product will be launched by the company?
According to the CEO of AGM Engine, the AGM-60 twin cylinder gas engine is accept pre-order for several days. Users who have pre-ordered this item will really receive their parcel in the end of this month. It is said that, the newest 60cc gasoline engine will taking gas engine to another heights as it can generate and provides more steady power to RC model airplane.
Anyhow, let's have a glance of the specification of AGM-60 provided by AGM Engine.

From the above information, we can see that the engine seems to be the perfect engine. While some skilled players maybe concerned about the compression ratio as it seems a little low. Generally, we suggest players choose the ratio between 8.0 and 12.0, those engines can serve enough and steady power without any pressure.
There are many factors we need to consider when choosing RC hobby engine for our model. Horsepower and static trust are the most concerned factors by most people I think. And I personally add that everything is imperfect. Though 7.6 seems a bit little low while it has a good economy advantage and practical usage. As a whole, the horsepower 7.0hp is good enough to enjoy your smooth and long time flying.
From the engine design, the twin opposed cylinder is very common in twin gas engines. The biggest advantage is it can balance the engine especially when it is running in idle state. In the same time, this design keeps the engine size stay small and has a nice looking.
Packed with two mufflers, two spark plugs and specified auto advancing electronic ignition system, the AGM Engine Company direct sell it to customers with USD $399. Comparing the 60cc twin gas engine for sale in the market, it is hard to find an engine selling under $400. According the CEO of AGM, they are striving to work hard to benefits users more.
