After struggling for almost 2 weeks editing and rendering, this Piper Cub build video is finally released. The problem started when I tried new style of shooting on the build steps, but it ended up a disaster. The result was not watchable with 5X speed timelapse as usual and the lighting also terrible. I need to re-edit and failed render multiple times. This is the best that I can give to you, I think it`s better than before (the first render) but still my worst production. Although I think you can still follow my build easily, just like my other videos, only the quality is not good.
Beside that, the model itself the Piper Cub is awesome. It flies great, very slow. My last flight was on the last weekend it fly very slow with only 40% throttle but I didn`t record it. The flying scene on this video was shoot 2 weeks ago. The design is very similar with Cessna 172 build style, but this Piper Cub has more details and longer build time. The CG is spot on, doesn`t need any counter weight ballast on the nose.

It seems like putting the word "Drone" or "FPV" in front of the word "Backpack" puts the price up exponentially, so today I`m looking at a much more reasonably costed...
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!
