Overall, the BD4C is an odd-looking but high-performing plane. Its performance numbers are impressive, and it is relatively fuel-efficient. The design is not perfect, but it works well for the intended purpose of fast, experimental flight.

Thrust Vs Drag

When it comes to fast planes like the BD4C, the key to their speed is a matter of thrust versus drag. The BD4C is known for its good performance, being able to cruise at 150 knots or more, but the real question is how it achieves this speed.

One way to reduce drag is through the use of retractable gear, but the BD4C doesn’t employ this method. Instead, the BD4C reduces drag through its short wings, which produce less drag than larger wings. However, this design also means that the BD4C is less effective at flying slowly and has a higher wing loading, requiring higher speeds for takeoff and landing.

Despite its good performance and relatively low cost, the BD4C’s design may not be for everyone. Its short wings and unconventional appearance may not appeal to everyone’s taste. Nonetheless, for those who appreciate the BD4C’s unique design, it remains a popular choice in the experimental aircraft community.

Wing Design and Influence

The BD4C is known for its fast performance and roomy four-seat experimental high wing design. Despite its unique appearance, the BD4C’s small wings produce less drag than larger wings, making it an ideal choice for flying at high speeds. The ratio of weight to wing area, known as wing loading, is relatively high for the BD4C, meaning it needs to fly faster to produce enough lift to take off and land.

While retractable gear is a good way to reduce drag, the BD4C’s drag reduction lies in its short wingspan of just 26 feet. This design feature produces less drag and allows the aircraft to fly faster with less fuel consumption. The lack of rivets in the wings also contributes to the drag reduction.

Compared to other popular four-seat experimental aircraft, such as the RV10, the BD4C’s wings are about six feet shorter. This makes the BD4C better suited for flying at higher speeds but less effective at flying at slower speeds.
