I have authored several aircraft design software projects, and make it available here as freeware. Downloads are below.
My latest is a helicopter performance program in vertical flight mainly to be used by radio control helicopter pilots. The
head speed, pitch angles, and resultant performance can be shown in graph form. This should help with the programming of
computerized radio controls (throttle and pitch curves) so that settings can be measured and tested "in the lab"
to have the desired flight performance. Version 1.10 Aug 15, 2011. Note: since I am a new RC helicopter pilot, the example
files that go with the software are rather thin. This is where you the experienced pilot can save files of your own successful
settings (throttle and pitch curves, pitch ranges), and use them to figure your next helicopter of a different size. Also
I would appreciate it if you could email me some interesting examples so I could fill out the sample files.

Next is a simple to use V-n diagram application. V-n is of course velocity vs. g-load, the structural constraints of
flight (without the additional factors of safety). It makes doing preliminary aircraft trade studies easier. Download the
zip file and unzip it. Then double click the Setup.exe file and follow the instructions. Try it, you'll like it! All created
in VisualBasic5. Version 1.5 March 2012
