Notes and Details

A fairly successful first flight for Joey but being below 434MHz receivers suffered a lot with ISM band noise. Work to commence on Joey to bring it to a frequency above 434Mhz to avoid that problem on the next flight. Everything else worked very well, GPS kept a lock and nav mode was set up correctly. Temperature drift of the Micrel MICRF112 radio was worse than NTX2 but acceptable, better than expected. Shift was very stable.
