The is my scratch build 47" flying wing that I will be using for FPV in the near future. I haven`t decided what motor/esc combo I`ll be using. This wing design came from another you tube member FPVTrond.
Below is the link to his video tutorial on how to make this giant wing. His design is a for 49" wing. This is my version of it. The material that I had laying around only allowed me to build at 47"
This technique of 3D printing the wing ribs to hold a true aerofoil shape worked out super well! Combined with foam sheets, packing tape and the lightweight wooden spar, it performs amazingly well!
