Possible... yes. Practical?????

To get the range you want, you're going to have to be able to carry a LOT of fuel. The current mdel jet engines such as those from BVM can operate for long enough IF your plane can carry the fuel.

Which power plant is used doesn't matter much as far as the control circuitry for having the plane fly and land itself. The GPS control system used for the cross-atlantic flight a year or so ago would do just as well in a jet as it did in the prop driven plane.

Yeah, them model turbine engines are.. thirsty!

Not to mention a bit of a proceedure to get the thing up and running. (most scale jets require and external fuel tank just to get started and up to their take-off run, to maximize flight times. There's a few videos of the start-up proceedure on our site..)

Typical ones will run 5 minutes on about 20 oz of kerosene..

Prop'd 2 stroke or 4 stroke no good? Can we ask why a turbine?

I don't think you're going at this a very good way. Flying a jet unmanned is NOT a good idea. If it crashes there is just too much of a risk of a fire etc.
Also, a BASIC Stamp is really, really slow. If you use Atmel AVRs (which are much cheaper, ~$5, and much much more powerful) you can get GCC, a C compiler, for free. BASIC is easy to learn & use, but is not intended for such a complicated project.

These sites have some info about hobbyist UAVs:
http://autopilot.sourceforge.net/ - a helicopter that has hovered succesfully (by itself). Code & PCB schematics are available.
http://www.auav.net
http://members.shaw.ca/sonde/ - this one is carried up tail-first by a weather balloon then glides back down (really! you have to see this one.)

OK I think I got the links to work now [img]i/expressions/face-icon-small-smile.gif[/img]
