RE: 10c vs JR 9303
I've owned both radios in the past and if i had to choose between them i would go with the Futaba.
But i now have the Airtronics SD-10G which i honestly believe is a superior radio in terms of programming functionality, ease of use and value for money.
Airtronics' FH3 2.4Ghz system is FHSS just like Futaba's but also has extra features like failsafe on all 10 channels and "Safety Link" which is similar to Spektrum's Model Match but with added functionality.
