No man, This is it: if (!network) { navigate_to_location(home_of_my_boss); decend_flight_level(100); holding_pattern(); } This would be rather effective with my raptor chopper as it makes a terribly annoying noise. Actually, on a serious note, I have often thought about incorporating a GPS into a RC plane and programming it for a specific flight plan, including takeoff and landing, maintaining specific speeds and such... but the one thing I never investigated is if you can use a GPS to get the current altitude ? I wonder how difficult it would really be to actually implement something like this. :-) -----Original Message----- From: pic microcontroller discussion list [mailto:PICLIST@MITVMA.MIT.EDU]On Behalf Of Marc Nicholas Sent: Sunday, June 15, 2003 10:38 PM To: PICLIST@MITVMA.MIT.EDU Subject: Re: [EE]: RC control w/ cell phone If (!network) { holding_pattern (); } ;-) -marc -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
