I wanted to build a FPV wing style plane similar to a Mini Drak and have the crash resilience of a quadcopter! I chose the FT Goblin and fluted polypropylene board as this mixture fitted my requirements.
I have been building and flying FPV quadcopters for a few years now and like many I progressed into RC planes, starting with Flite Test foam board builds. I have provided the plans to print and a resources folder along with individual component photos and weights. I used DSM to improve and refine my design, I then rebuilt the fuselage and posted YouTube videos of the build process. I then used “Design Spark Mechanical” free CAD software and plotted the build. I did some test flights and after many crashes! I worked out the C G for my plane. I then designed and built a fuselage out of 3mm Correx. Depending on what your sheets are made of, use polypropylene glue for polypropylene and use CA glue for PVC (hot glue should work on both).
I modified the spars and assembled the wing similar to the Flite Test build video. I started with the Flite Test Goblin plans for the wing, I printed them out and used “Spray & Stick” temporary glue to mount to a piece of 3mm Correx sheet.

Of 3 & 4mm fluted plastic sheets(Correx).It’s based on the Flite Test Goblin. The Vector is a radio controlled first person view polypropylene/PVC plane I have designed and built from sheets
