I have no idea about controlling an aircraft.

ARM boards look very much like a compromise. That rarely pays off. Likely there exist better solutions for a model aircraft, but I cannot judge that. > To make this on topic for this newsgroup, this seems to be a common > hobbyist or researcher project in a number of circles, and is _exactly_ > the type of project for which Ada would be very well suited indeed. How many people spend their time building model aircrafts? Could rail transport modeling be a better candidate? Anyway, if you need an altimeter instrument for the ground control system, let me know. I maintain an instrumentation library in Ada. > Question 2: how would you put the idea of using Ada for this project > into someone's head and what changes to the Ada ecosystem would be > needed to make it viable for people with different ranges of embedded > experience to actually use Ada in this case ? I would tell him that he could use the same software during modeling and deployment phases, basically, doing much of the work in doors rather than in field. -- Regards, Dmitry A.
