I'm trying to compile a (very) subtly modified version of Arduplane 2.74b using the IDE downloaded from the Arduplane website (1.0.3) but it hangs when I try to compile. Actually, it doesn't hang…Continue
Does anyone know any way of mapping the servo mid and end points that APM uses?I have modified elevons on my Skyfun which, unfortunately, have a limited down travel. If the elevon servo forces it…Continue
A climb-glide routine can potentially yield a useful increase in range compared with the same airframe/propeller/motor combination operating straight-and-level at best range speed point or best endurance point respectively.
Let me explain briefly with graphs of the results how I have come to that conclusion, at least theoretically so far, hopefully…Continue
The flying wing design I have been working on for some time now has been slowly evolving as I have learned more about aerodynamics and expanded my skill set with modelling tools of various forms. I have recently completely re-surfaced my design with new aerofoil sections and better, more consistent surface transitions and have been experimentally analysing the results…Continue
A very interesting and thought provoking explanation of why the conventional wisdom of elliptical lift distribution needs rethinking. Interesting for lovers of fixed-wing but also might be applicable for propellers and rotors...?
