I have been using airtronics RDS8000 for some time and certainly is a radio to consider, however I must say that that the hardware should be improved. After 2 year, the wall charger is broken and I had to replace the TX. battery. Also I had inspected the gimbals wires like 5 times just to make sure that they are fine. However it is a very reliable and stable plataform for a reasonable price.
I would buy sd-10 if I could used (FHSS-3) with analog servos.
