    AtoZ of RC hobby+DIY radio with ARDUINO

    Few weeks ago I started to build my first RC plane. Surprisingly the design is very similar to yours, maybe because i also wanted to make it fully by myself and the parts must be really cheap. Cons and pros in this design:1. parts are really cheap. Arduino chip costs ~2usd, joystic ~1usd, RF24L01+PA ~3usd.2. you can transmit back telemetry (battery voltage, barometer or gyro data)3. Transceiver is heavy, I wonder if it will be possible to remove that heavy antenna connector, and solder other lightweight antenna.4. RF24L01+ uses 5 arduino digital i/o's , so there's only 7 left (of which 3 (if to connect radio to 9,10 pin.) or 5 (radio on 7,8 pins)are with pwm). so in my case i can control only 3 pwm channels5. It would be nice to find out how to increase tx/rx distance. Maybe to put anot...see more »Few weeks ago I started to build my first RC plane.

Im already using 256kbps and full power link, but maybe there are some other parameters to get maximum out of this transceiver?
