5 Drawbacks of Sport Cub S

Sport Cub S RTF uses HBZ4400 and BNF uses HBZ4480 motors. Which are brushed motors. The replica of the sport cub aircraft was popular when it came out.

Yet, as with any other electronic device, this RC airplane also has many drawbacks.

Short-lasting Battery Life

Many RChobbyists have complained about the very short battery life of Sport Cub S. The flight time and battery life of Sport Cub S RTF and BNF are short lasting.

Currently, the Sport Cub S has a 1S Lipo 150 mAh 3.7V 25C battery.  With this battery, you can fly the airplane for a maximum of 5 – 6 minutes. And a fully charged battery lasts for 5 minutes. 

Unstable Wings Against Strong Wind

Another drawback of the Sport Cub S is that it’s difficult to fly when it’s windy. Even at a low speed of the wind. The wings start to wobble making the airplane unstable when flying. And the instability of this airplane is what the users have mentioned the most. The plane is an excellent RC plane to fly for beginners. Yet the instability of this plane is a hinder to having a pleasant flying session.

The upgraded model Sport Cub S 2 has 3 modes for better control and stability.

Small Fuselage

The fuselage of Sport Cub S is only 16.3 inches in length. The sport cub S’ fuselage is comparatively smaller than any other RC airplane. 

This restricts the airplane from getting drastic upgrades. Because the fuselage won’t be able to accommodate the changes.

You will have to keep this shortcoming in mind when you upgrade your plane. 

If not, the upgraded parts will falter the overall balance of the plane. 

The Top Speed Is Not Up To The Mark

The flying speed of Sport Cub S is an airplane for beginners. Being a beginner-friendly RC airplane, the top speed of this plane is not high. 

The top speed is not as fast when compared with an advanced or bigger model plane. 

The reason is that the servo and the motor is not strong enough. The propeller is also a small one with a diameter of 130 mm.  

Motor Type Not Energy Efficient

Sport Cub S RTF uses an HBZ4400 and BNF uses an HBZ4480 motor. There is no significant difference between the two motors.

However, the motors are brushed, which is not energy efficient. Because the brushed motor has frictions caused by the stator and rotor. Which generates heat and that heat results in energy loss.

Starting from the motor to batteries, you can upgrade a few parts of this plane. Subjective to your needs, upgrading Sport Cub S is worth it .

This will be more energy efficient. Because the brushless motor’s magnet levitates in the center of the coils. As a result, it doesn’t have friction issues. This means, no heat production, no energy loss with heat, and quieter. 

Sport Cub S Upgrade Battery
