Last fall I bought a DX8 and it has worked fine for my electric pattern plane. However, last week I programmed it to my 40% gasser and found a disturbing element. When at idle and I put a little pressure on the idle stick, the rpm changed. There seems to be no hard stop on the gimble.
Do I need to send the radio in for repair or is that normal ?

Hope this isn't too far off topic

Thanks
Randy
