Dear Davy,

Thank you very much for sharing your experience and code with me/us.
I'm sure I will learn a lot from your experience.

THANK YOU

Hi Lora,
Inspired by FMS I started writing a R/C simulator last year. Never got
around to finishing it though. But I figured out a working flightmodel.
Mostly by directly implementing some basic physics. Of course I haven't
documented my code well :-) but maybe it's a start for you. If I remember
correctly it worked pretty well, but some tweaking is needed when pitch
approaches -90 degrees. Sorry about the long post.

Good luck!!
Davy




Very cool, gang, I've never done anything in Delphi, only in Fortran, but it looks good. Looks like you stopped short of making the graphical part (am I right here or not?). Seems like that would be a challenge, but maybe not as hard as I think for someone familiar with it.
It looks like you're applying all the forces to the plane as a whole, and airflow is regarded as uniform over the whole plane. Note that without using a velocity-panel type model, where airflow is calculated individually at each location, that you will not be able to do any non-linear maneuvers, such as spins, snap rolls,lomcevaks, etc. but then again, this is how many commercial flight sims are made.
Good job.
