Where should the CG be on a flying wing?
A: The center of gravity should be located at or near the center of lift, which is 20-25% down the length of the mean aerodynamic chord (MAC). Because a delta wing is shaped like a triangle, the center of gravity isn’t right in the middle.
What is a good wing loading for RC planes?
This is calculated by taking the weight of the plane and dividing by the wing area. A good rule of thumb is for a 40 size trainer one would expect a wing loading of about 16oz/sq ft and will be a docile flier.
What do you need to build an RC plane?
Below is the list of electronics:
- Transmitter/Receiver.
- Battery.
- ESC (electronic speed controller)
- Brushless Motor.
- LiPo battery.
- Servos.
- Servo extenders and spitters.
- 2mm gold bullet connectors.
How do you make a delta wing?
Instructions
- Fold a sheet of paper in half widthwise.
- Fold the upper corners of the paper in so they meet at the middle crease.
- Fold the top of the plane down so that it meets at the same point as the two wing tips.
- Fold a margin on each wing.
- Fold the plane in half.
- Now it’s time to fold the wings.
How do you tell if your RC plane is balanced correctly?
A correctly balancing rc airplane, sitting on your fingertips, will either be level or have the nose pointing slightly downwards. If the tail points downwards then the plane is tail heavy and you need to do something about that.
What is a high wing loading?
With a higher wing loading, a given lift-to-drag ratio is achieved at a higher airspeed than with a lower wing loading, and this allows a faster average speed across country. The ballast can be ejected overboard when conditions weaken or prior to landing.
What is the best foam board for RC planes?
I still think Readi-Board is great foam from which to build airplanes. It’s perfect for beginners and seasoned hobbyists alike. More recently, I’ve been going back to uncoated foam sheets for my new airplane designs. The one I’m using now is Fli-Power Value XPS RC Model Foam (fli-power.com).
How much does it cost to build an RC plane?
An average turbine aircraft will cost between $150–$10,000 with more than $20,000 all-up becoming more common. Many manufactures sell airframes such as Yellow Aircraft and Skymaster.
What’s the cheapest way to build a wing?
This is not a unique build – it is a result of reading through many other builder’s experiences and scratch builds, with the goal of designing and successfully flying the least expensive, fastest to build delta wing. The wing profile is based on a simplified KFm airfoil design (KFm-2).

How big is a flying wing in RobotShop?
The board looks like thin foam sandwiched between paper and is around 3/16” thick (or 5mm) and very light weight. It almost always comes in white, though black can often be found too. Dimensions sold seem to be around 20” x 30”, or 800mm x 1000mm.
What are the control rods for a flying wing?
The control rods will link the horn of the servo to the control horn installed in the ailerons. The ideal control rod for this application is the metal handle which can be found on many Chinese / Asian takeout boxes. Metal coat hangers tend to be too thick and heavy for this application.
