The article from The Armory Life by Friedrich Seiltgen explores the Vought V-173 Flying Pancake, an innovative American disc-shaped aircraft developed during World War II. Conceived in the 1930s by Charles Zimmerman, the V-173's unique design featured two large counter-rotating propellers and a disc-shaped wing, aiming to eliminate drag and improve flight performance. Despite its unconventional design and potential, the aircraft faced issues like heavy controls, severe vibrations, and difficult landings. While Zimmerman and Vought Aircraft continued to develop the concept into the XF5U Flapjack—a more advanced version intending to serve as a carrier-based fighter—the project was ultimately canceled due to the rise of turbojet engines and changing military priorities post-WWII. The V-173, though never fully realized as a successful military aircraft, remains an important part of aviation history, now restored and displayed at the Frontiers of Flight Museum in Dallas, Texas.

How Does A Drone Propeller Work?
Drones are becoming increasingly popular for recreational flying, photography, or professional applications. But have you ever wondered how these nifty gadgets get airborne? The secret lies in their propellers! Let's break it down.
The Basics: Lift And Thrust
Drone propellers generate two key forces: lift and thrust. Lift is the force that helps the drone overcome gravity and stay in the air. Thrust, on the other hand, is what propels the drone forward. The magic happens when the propellers spin high speed, pushing air downwards and creating lift. This is similar to how an airplane wing works, just with a bit more spinning action!
The Science Of Spinning: Clockwise And Counterclockwise Rotation
Drones usually have four or more propellers, but not all spin in the same direction. They are paired to rotate in opposite directions: some clockwise (CW) and others counterclockwise (CCW). This is crucial for stability. If all the propellers spun in the same direction, the drone would just spin uncontrollably on its axis! Pairing CW and CCW propellers cancels out the torque effect, keeping the drone steady and easy to control.
Pitch And Size: The Power Players
Not all propellers are created equal. The pitch and size of the propeller play significant roles in determining how the drone flies. The pitch refers to the angle of the blades. A higher pitch means the drone can move faster, but it also requires more power. Similarly, larger propellers can lift more weight but may reduce agility. This is why finding the right propeller size and pitch is essential for optimal performance.
Materials Matter: Durability Vs. Performance
Propellers can be made from various materials, such as plastic, carbon fiber, or even wood. Each material has its pros and cons. Plastic propellers are lightweight and inexpensive but can be prone to breaking. Carbon fiber propellers are durable and offer better performance but come at a higher cost. The choice depends on what you value more: cost-effectiveness or top-notch performance.
Fine-Tuning: Balancing Act
For smooth flying, propeller balance is key. An unbalanced propeller can cause vibrations, which affect the drone's stability and even damage its motors over time. Many drone enthusiasts use balancing tools to ensure their propellers spin perfectly.
Wrapping Up!
In a nutshell, drone propellers are like the wings of an airplane but with a modern twist. Their design and performance are crucial for a drone’s stability, speed, and efficiency.

Best Cinewhoop Drones and Parts in 2023
Understanding Cinewhoop Drones
Cinewhoops are a specialized category of mini FPV drones featuring ducts for propeller guards, designed to carry action cameras like GoPros for capturing smooth and cinematic aerial footage. Cinewhoops prioritize stability and safety over speed, allowing pilots to fly safely in close proximity to subjects, both indoors and outdoors. Their unique design makes them ideal for achieving cinematic-quality shots that are challenging to replicate with traditional 5" freestyle FPV drones.
Advantages of Cinewhoop Drones
Safe indoor flying with added protection from propeller guards
Capable of flying slowly and smoothly, perfect for capturing cinematic shots
Cost-effective due to their smaller size and components
Disadvantages of Cinewhoop Drones
Shorter flight times due to less efficient propeller, motors and added weight
Slower and less agile compared to standard freestyle drones
Not suitable for aggressive freestyle maneuvers
Factors to Consider When Choosing Cinewhoop Parts There are four sizes of cinewhoops available: 20, 25, 30, and 35, which correspond to propeller sizes (2", 2.5", 3", and 3.5"). Let's explore how to select the right cinewhoop parts based on these different sizes.
Propeller Size Selection When choosing the best propellers for your cinewhoop, consider the following factors:
Efficiency: How does propeller choice affect flight time?
Noise Level: Quieter propellers are less disruptive.
Power: Evaluate thrust and throttle requirements for hovering.
Smoothness: Check for vibrations introduced by the propellers.
Responsiveness: Assess how propellers impact flight performance.
Best 2-inch Props for Cinewhoops
The Emax Avan 3-blade propellers offer an excellent balance of performance and efficiency, with impressive flight times, especially at cruising speeds. The Gemfan 20354 and Gemfan 20364 also provide excellent power, although they may require larger motors.
Best 2.5-inch Props for Cinewhoops
The Azure 25403 stands out as one of the most efficient 2.5" propellers, offering long flight times while still delivering adequate thrust. The Emax Avan 2.5 inch propellers are also powerful.
Best 3-inch Props for Cinewhoops
After testing various options, the GEMFAN D76 DUCTED 76MM 5 BLADE props provide a great balance of thrust, noise level, efficiency, and mounting options for 3-inch cinewhoops.
Motor Selection
Choosing the right motor is crucial for cinewhoops.
For 2.5-inch cinewhoops,motors in the 1106 to 1408 range have been tested.
The MEPS 1404 Brushless Motor is recommended for 2.5-inch cinewhoops.
For 3-inch cinewhoops, the MEPS 2004 3000KV motors are ideal for supporting an action camera while ensuring clear and jitter-free video.
Battery Selection
Selecting the right battery depends on motor KV, propeller size, weight, and desired flight time.
TATTU R-LINE 1050MAH 95C 4S XT60 is an excellent choice for a balance of flight time and weight, offering up to 6 minutes of flight while keeping your setup agile.
Frame Selection
Consider frames like the Beta95X V3 2.5-inch Frame for indoor flying, the iFlight BumbleBee V3 3-inch Frame for outdoor use, and the DJI Cinewhoop 3-inch DJI Avata for versatility and long flight times.
ESC and FC Selection
Using a Flight Controller with a 20x20 stack is a popular choice for cinewhoops to keep the setup lightweight. The Mamba F722 Mini Betaflight Flight Controller & Mamba F40 MINI ESC is a compact option that works well with micro quad FPV racing.
Camera Selection for Different Cinewhoop Sizes
2-inch cinewhoop: Ideal for staying under the 250g weight limit with a bare GoPro or other action cameras. Some models offer compatibility with DJI O3 Air Units for a compact setup.
2.5-inch or 3-inch cinewhoop: Suitable for carrying a Naked GoPro or GoPro Bones, providing better outdoor performance.
3.5-inch cinewhoop: Best for flying outdoors with a full-sized GoPro like the GoPro Hero 11 Black.
Top RTF Cinewhoop Recommendations in 2023
GEPRC 2-inch Cinewhoop (CineLog20)
SpeedyBee 2.5-inch Cinewhoop (Flex25)
DJI Avata 3-inch Cinewhoop
In 2023, cinewhoop drones offer various options for capturing cinematic footage, making it essential to choose the right combination of parts to meet your specific needs.
