FlySky GT3B 2.4ghz radio system

[Bondonutz]

I purchased this same radio a couple months ago and have hit and miss luck with it at best. This thread has inspired me to trouble shoot and disassemble it.

The first few times I used it it worked flawlessly, slowly but surely It started acting up. I thought at first it was the ESC because the RC would cog and hardly move backwards. Then I tried reprograming the TX to the ESC and never could get the reverse function to work again regardless what I did. At best the reverse would work as described earlier as cogging and no power. A different radio and RX and everything worked perfect. I then tried the 6 different Flysky RX's I have and all did the same, then I tried multiple ESC's and the problem presists. I firmly believe it's the Forward and Reverse switch on the TX. I've removed it and sent a email to Flysky asking if this part can be purchased seperately. I would like to test this at home but have no idea how. Can this switch be found at the local RadioShack ?
