Out in the country earlier today testing a project for a client, for large-scale aeromodeling.
A 'faithful reproduction' of a reverse-engineered Shahed-136. Designed on FreeCAD, analyzed with Flow5 (VLM) and OpenFOAM (CFD). This prototype was made over two weeks, including mold production. All manual control on this one, but can use a Pixhawk down the road if automation or FPV control is desired. The machine flew as expected with pleasant flying qualities and exhibited the docile stall behavior you'd expect from a delta wing. Some ATV trimming needed to lower the roll rate but overall, good bird. Ideal for those long-range Minecraft 'special package delivery' missions when that championship series kicks off in due course.
Easy build. If I were to improve anything, I'd taper the aft fuselage to shave off some drag, improve prop efficiency and increase overall range & cruising speed.
