How to Set Up a Cooling for Your Gas Engine?

RC players must have heard about the cooling system before, if you want to make a good cooling for your hobby engine, you should keep the following two tips in your mind.

First, the air should pass through the gas engine cooling fins and not take the easy route around the hobby engine with less resistance. Engine baffles and jackets to guide and force the air go through the fins must have adequate dimensions are two necessary elements.

Second, if you want to achieve an air flow, you must make sure that there must be a pressure difference.

However, how can you set up a different pressure?

There should have two pressures in order to produce the pressure difference, a high pressure is needed in front of the baffle and a low pressure after the baffle. If you are planning to gain a high pressure, you should make sure that the centre of the prop is designed as a very lousy fan, and it is used to stir up the air.

The turbulent air is good for cooling the front of the engine, when the airplane has a decent forward speed, the incoming air will provide a pressure high enough. While when it runs at a low speed and long verticals, the speed will become low and high pressure will be absent at that time. However, low pressure can be achieved by carefully looking at the flow around the cowl and making use of the high speed prop blast that hugs the fuselage.

But for the radial cowls, if the cowl rear edge flares to a slightly larger diameter than the fuselage, then the gas airplane engine will greatly enhance the cooling. As we usually see, black is the basic baffle, and the added jacket of purple is the ultimate in cooling.

So it is very important for the RC players to set up a cooling well for their RC engine, and once you have set it well, can your power generator do a good work for your airplane and then gain a wonderful performance in the sky.

How to Adjust the Speed of Two-Stroke Electric Engine?

Two-stroke engines are widely used in many applications, such as motorcycles and small-engined devices like chainsaws, outboard motors, RC models. For electric motor, you may have to buy another ESC (electronic speed controller) to control the running speed. While for engines, you can control the speed by adjusting reduce the volume of the fuel mixture and gas ratio to accelerate and decelerate…
