Hi guys this video is done in one hit pretty much the whole process of upgrading the Turnigy 9x to an er9x Radio. I decided not to split it up because I know I hate watching part 1, 2 and 3 videos. I know its a lot more logical to do it that way if your focus is on revenue with Google Adsense, but I'm guessing if I don't like that then neither will you.
but I got mine from ebay only because I was in a hurry to do this mod.
The board I purchased was from ebay and if you search for item 300695243866 you should find the exact one I purchased. Having said that if you search USBASP USB ISP AVR Programmer etc you should find one.
Its worth noting that while flashing my son's 9x it didn't have the battery in it. Also if you are doing changes to your TX via the PC, make sure you TX is not powered.
