Optic 6 Sport 2.4 GHz Transmitter and Receiver

I did weeks of research before I bought my first Optic-6. I like the Optic-6 so much that I bought 2 of them over 3 years ago. It was my first computer controlled 6 channel radio system. I find the value was great and it's always up to date. It's modular capability has allows me to go fly on all the 72M channel frequencies with the "Spectra" Module. By design it can control all basic PPM planes, gliders and helis whether their receivers are made by Hitec, Futaba, Jr or Airtronics. It also accepts the Spektrum AirModule so I can fly the popular BNF series models just as if I had a Spektrum DSM/2 TX. Great mixing capabilities, both standard and custom. Easy to program with good examples in the manual. The only shortcoming I have found is that it's limited to 8 model programs. Guess that's why I own 2 of them. Both of mine have been superbly reliable. I have never had so much as a single failure or crash that was related to this radio system.
