Hi Mick,
Both have a lot more range than you will ever need with a heli. Frsky goes around 1.5km and 9x 1km. The QC on 9x is sort of non existent so every one and then you will get a receiver which only goes 100m or less but they are faulty pieces best thrown away.
With both you are responsible for quality control (much more with 9x than frsky) but range is not a concern with both systems, even less with small helis.
P.
The difference between men and boys is the price of their toys!
