Gonna be doing the telemetry mods on mine as soon as I get my r9m module delivered. I've been doing some research online, and most of the results pointed to old posts on this forum wondering how reliable the ed040502 h16d 1102 chip would be running this, and people talking about swapping it for genuine atmel chips, but for the meantime I want to see if it's not needed.
So far I've flashed er9x with no issues and everything seems to work fine if flashing with the m128 option on eePe with the stock 2,4ghz module. Some messages while flashing from eePE about the clock speed being off but that seemed to be all. Will update once I do the mods so people can search for the results.
