Scratch build micro size 24″ wingspan super fast and stable foamie flying wing.
Airfoil
Below are the airfoils we will use for root chord and tip chord. Right click on image and download to your computer. Print at 100%. Airfoils can be laser cut if you have access to a laser machine, or simply use balsa wood, or aluminum or even cardboard to cut out the shape of the foils. In the build video i use 2mm hard balsa wood, its easy to cut with exacto knife and fairly rigid for hot wiring.
Wing Spar & Pushrods
for the main wing spar, we use 3mm x 2mm hollow carbon fiber tube. This will provide structural strength to the wings. You are welcome to use flat carbon fiber spar, just make sure its light weight, 4mm or 5mm might be too heavy. Wooden dowels can also be used.Pushrods are also 1.5mm carbon fiber rods. You may use thick wire if you do not have carbon fiber, but again we want to keep this wing as light as possible for maximum speed, agility and ease of flight.
Foam
Any type of foam can be used for this micro wing project. I like using XPS foam as its dense and light weight and virtually unbreakable.
