The third flight for 2014 is being scheduled to test the Telit GPS module again. During the 2014b flight, the JN3 GPS module proved to be inadequate for high altitude ballooning. After consulting with the Telit support, it was determined that the Telit SL389 v2 module should work, but sourcing that module proved to be difficult.
All of the issues with the new controller on 2014b have been resolved, and the firmware has been updated on the new controller and should be ready for a final production build after this flight if the GPS proves reliable.
Many new enhancements to Balloon Finder have been wrapped into the latest releases. Some of them haven't been released to the public yet, including an exciting new feature where the position of the balloon will be audibly announced at intervals throughout the flight.
I have some new smaller LiPo batteries that if I can find time to test, I would like to fly them on 2014c to shave off another 50g of mass.
