If you fly a twin-motor glider that uses differential thrust for yaw control (or as an aid to steer without relying on the rudder), trimming the tail is part art, part engineering — and absolutely worth doing. A properly trimmed tail makes the airplane fly straight and hands-off in both… Continue reading
An RC helicopter and an RC glider both use the same principle of lift to fly, but they go about it in very different ways. A helicopter creates lift with its spinning rotor blades. Each blade acts like a small wing, and as it spins, it pushes air downward. That… Continue reading
This may look a bit off topic, but many of the simple and cheap RC gliders work exactly like PCA. When we think of airplanes, we imagine wings, rudders, and elevators working in harmony to steer a machine through the sky. But what happens if those controls fail? That’s where… Continue reading
A phugoid is an aircraft motion in which the vehicle pitches up and climbs, and then pitches down and descends, accompanied by speeding up and slowing down as it goes “downhill” and “uphill”. It has a nearly constant angle of attack but varying pitch, caused by a repeated exchange of… Continue reading
This kind of small RC plane motor (N20) is 2S capable and is very powerful (rpm no load is 38000). The problem is that it has a very thin and short shaft, that prop mounting can be challenging. Also, it gets hot easily, that the shaft can become hot enough… Continue reading
Smaller RC Planes are more sensitive to wind and turbulence due to low mass. They are often more twitchy or unstable, especially micro planes or indoor flyers. A gyro often helps stabilize and makes them more flyable, especially for beginners. A multi-axis gyro detects and corrects movement around multiple axes… Continue reading
The props can damage during crash landing. Adding a protective shell can prevent such damage. Any light weight plastic container will do…. Glider propellers are deceptively fragile. Even though they look simple, they take a lot of punishment in their day-to-day life, and there are several ways they can get… Continue reading
When flying an RC glider, making a sharp turn can significantly increase the area of the wing exposed to the wind, making the glider more vulnerable to being blown away by strong winds. This effect is due to the interaction between aerodynamic forces and wind resistance. During normal flight, the… Continue reading
