Thanks !
i used big resistors to make it easy to change them to adjust the OPamp that amplifies the absolute pressure signal therefor effectively giving it a much broader range and sensitivity . the heat sink is a dimension engineering 5.0v switching reg.
after further testing my home made PCB developed a connection problem on the pitch gyro so i had one made , ordered some solder paste ,found a small fridge and SMD'd the ICs from my beat up 5dof and lisy300 the SMD process worked great (used skillet as suggested on sparkfun ). and here is the result
AP
accept for the lisy300 every thing works as for the lisy i forgot to ground the PD and ST pins DOH !!
new board is on its way.
another good flight today . both roll and pitch stabilized . time to start engaging my nav routine wich has been giving me great numbers . you can view flight in goog Mykml233402.A.kml
and view the log Mylog233402.A.csv
thanks,
1500 meters = .932 miles
line of sight is about .25 miles . figured i should be good.
i should be flight testing next week will let you know how it works
Comments
code now commented and posted to google code . enjoy !!

Why do you use the big through-hole resistors, and what's the thing in heat-shrink at the bottom?

, 3 flight tests in so far , 2nd a 3rd test with acceleration compensation KML for goog1500 meters = .932 miles

Sparkfun says it can do 1500 meters, but I don't know if that's just theoretical or actual performance.
Also, very nice servo control!
