I cant dispute this at all, I've personally never tested it (I always used to use a redundant satellite when i was using Spektrum) but it's strange to say the least that only Spektrum should need these additional receivers when all are brands are now using the same diversity antenna primary receiver technology.

Is Spektrum's RF performance really so much worse than all other 2.4GHz protocols? This seems hard to understand given that they have been doing the 2.4GHz 'thing' longer than any other brand and have had three iterations of their DSM technology in which to 'get it right'.

Idle curiosity on my part because i dont have a dog in the fight anymore, I'm on Jeti now and using a single receiver with no issues.
