Yea I better not go into detail here of my adventures in the F100 Super Sabre..
when I got the order to abort, so many lives at stake...

Yes, one problem here is that the government decreed the whole area to a no fly
zone
for model aircraft.. I am close to Leeuwarden mil airbase.
One reason I do not fly this one:

  serves more as ornament, wrote a whole lot of stuff for that though.
But it needs space, 160 km/h.

I also wrote the software I use to program the PICs, the hardware is based on
the noppp programmer,
just modified it a bit for the modern PICs:
 http://panteltje.com/panteltje/pic/jppp18/index.html
uses PC parport, using a PCI card with parport connector in the modern PC..


did many PIC projects, some are on my site:

As to that BASIC: in my view asm is often simpler, indeed the PIC hardware is
nice.
I use an asm math library written by someone else, so far 32 bit integer was
all I needed,
In asm you do not have to worry about code generation by whatever... compiler
...

Also the PICs give you near zero boot time, near zero power consumption, near
zero weight, near zero cost (about 2$ a piece).
