I have 9 Spektrum receivers that I would be willing to trade. They are all 5 and 6 channel receivers that I used in park flyers and I now fly bigger models and don't need them. They are all in great shape:
(2X) AR 500
(2X) AR 6100
(2X) AR 6100e
(3X) AR 6000
Please drop me a line and let me know if you are interested.
