I don't know what your normal flight range is on the Aerobird, but I often fly it 200-300 feet up and over 1000 feet out. The feather receiver mentioned above only has a 1000 foot range. Your Aerobird receiver has a 2500 foot range.

Unless you are having problems with the Aerobird radio system, why convert? You are talking a bunch of money to gain nothing in range or performance. And the single stick controller on the Aerobird is very good.

I would not encourage the change.
