How to Build "Walet" - FPV RC Plane

I miss flying FPV but I don't have any plane for that. My last FPV plane, the Sky Arrow 1700mm is crashed and beyond any repair. So I made this RC plane that I named it "Walet". Walet is an Indonesian name for "Swallow", a small and agile bird. Actually I planned to make the wingspan 1300mm but I forgot to update the 3D model then it came out with 1400 plans. I think, what the heck, then I continue finishing the plans. Because it was surprisingly big, I released the smaller size plans, which is 1200mm. My Walet is already equipped with FPV setup now, but still manual, no flight controller and GPS yet. In this episode I share with you only how to build this plane, not the FPV setup. I hope I can cover about it on other episode.
