Since I started with this hobby, I spent a lot of time researching, window shopping at meeting and expositions. Sometimes simply planning what would the next plane look like, or how it would have had to perform. The A1-D model instead, was completely unforeseen. I wanted to know if I would have been able to make parts for another project with new materials, and I wanted to try these materials first hand. After a few tests, I had the idea of collecting all the possible upgrades to the Juliet and merge them into a fresh design, all while using the new materials and techniques.
The Juliet II prototype is more than just an evolution. Some ideas that I put into the design were in fact coming from the A1-C experience, but I started to draw from a blank sheet. As a matter of facts, the only parts which are really in common between the two planes are the ribs of the wing.
Although the external dimensions are still similar, the A1-D fuselage is almost twice as wide. This allows for easy access to the battery and all the components, even for my big clumsy hands. Having started the drawings with the electric propulsion in mind, almost half of the fuselage opens up with huge hatch/canopy. It still weights almost the same but with a better weights distribuition, while being several times more rigid.
Given that a lighter wing loading helps making a better flying model, I considered my options. Reducing the weight sensibly wasn’t a realistic achievement. Besides, the pure weight reduction was not the purpose of this plane. I already knew I was going to over dimension a lot of structural parts just to test how to make them properly, so even with better perfong materials used, my estimate was between the same weight of the A1-C2 and something a little above that figure.The only other way to reduce the wing loading was then to increase the surface. That is why I found a new wing structure, increasing the wingspan by a few centimeters, but the main gain in surface is given by the dramatic increase in the ailerons size. This is something I could actually still retrofit on the A1-C one day, depending on how well it will work on the Juliet II.
