Thank you very much for saying so. I am right now (11.45pm UK time) working further on editing the build video but have to stop now - too tired. I hope to finish it and have it up by the end of the weekend.
Yes, I was actually quite surprised on all my internet searches that there didn't seem to be much done in this manner with your 'everyday common or garden plastic bottles!'..... the wing support mount works really well and feels very strong, yet lightweight and secure. And the bottles, once glued and taped provide a very rigid lightweight fuselage (in my humble opinion) with minimal flex.
Like the versatility of foamboard for building model airframes fast and cheap, I feel the plastic bottle concept for the fuselage should be a good compliment. I only want to share what I have learned myself because I have learned from others who freely shared their knowledge and ideas with the RC flight community - Flite Test, Experimental Airlines and Mikeys RC etc.,
