Current issues:
UDP packets are sent only when moved with joystick axis. But when you start doing some fast action, it will flood the core with packets and helicopter will loose signal (falling down). This looks like DOS (Denial Of Service) attack on the core (CFOD). Without transistor the range is about 50cm. With BC548B transistor, it can fly in 15m area
