RE: parkzone t-28 receiver?
The receiver is unique and only available in the RTF planes.
In the T-28 it is 72 mhz but I don't know for sure if it's positive or negative shift. There's a discrepancy as to it being 4 or 5 channel.
It has an economical price in the T-28
The DX10 name doesn't mean much with in itself. They use the name with a lot of different radios?
