The angle of the horizontal stabilizer, often referred to as stabilizer incidence or tail incidence, is one of the primary controls for pitch in an RC glider, and its effect on a climb is directly linked to the aircraft’s trim speed. The core principle is that the stabilizer angle determines the speed at which the […]

Can You Use Cardboard Paper to Create Wings for a Cheap RC Glider
Short answer: In theory Yes, practically No. If you are diving into the world of RC gliders and looking for a budget-friendly way to get wings on your build, cardboard is an option that sparks plenty of debate in the hobbyist community. Let me walk you through what works, what does not, and how to […]
Trimming the tail in a differential-thrust setup
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 powered and unpowered flight, reduces […]
RC Chopper VS RC Glider: how they differ in generating lift
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 downward push creates an upward […]
Propulsion Controlled Aircraft: Flying Without Flight Controls
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 the idea of Propulsion Controlled […]
Differential thrust RC glider VS 3ch trainer – phugoid is the major difference
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 airspeed and altitude. When it […]
Is hot weather bad for RC gliding?
Take a look at this and share your thought (personally I found that RC gliding during 30+ degrees outdoor is a disaster, lift is real poor). You may also take a look at this video, which explains air density and flight: https://www.youtube.com/watch?v=11kBN75Ty2s
Small 7.4V motor for RC glider
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 to melt away some plastic […]
Smaller RC plane and gyro
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 to keep the aircraft stable […]
