FRANK’S RUTAN LONG-EZ
I attach a photo of the current progress of the Long EZ slope soarer I have 3D printed, enlarged in the software from a tiny model found on www.thingiverse.com . I have covered it in thin glass fibre cloth. The overall weight fully loaded is going to give about 19oz sq ft wing loading so a good breeze will be required. I used 10% infill when printing it, and could reduce the weight by going down to 3% infill if this is just too heavy. Elevons control only is the plan, with the small canard wing just providing stability.......? I managed to get a carbon tube inside the full length of the canard as this is very vulnerable. I used a brass tube with a serrated cutting end, I cut with a needle file. I think it would need a great big smack to take it off now. AND MORE FROM FRANK’S PRINT FACTORY! I have just completed 3D printing the parts of a new model, an Eclipson EGW-80. Photo attached of the parts. The 3D print files are not expensive anyway but I had a stroke of luck. I was online in my email when the Eclipson announcement of the new model came through. I loved the look of it, and thought it would make an ideal dramatic slope soarer, so I immediately bought it, I imagine I was the first to buy one. Link here: https://www.eclipson-airplanes.com/egw-80 Unfortunately the first three parts I printed all went wrong. They came back and were very apologetic, and said that they had made a mistake, and attached the corrected files, and also offered a 70% discount off any another model, which I have taken on the MXS-R which will now be my next major power project. Link here: https://www.eclipson-airplanes.com/mxs-r I have printed the parts using a 5% infill so they are very light but at present very fragile. I will cover them with thin woven glass fibre cloth as with the Long EZ canard, and a few bits of strategically placed carbon rods, with balsa for the elevons and it should be very light.
