Today while i was looking at my Eachine 250 racer quadcopter i decided to try my other camera on it. (Standard is the 1000tvl, i wanted to try my 700tvl because the low light mode on the 1000tvl caused bad light glares when flying in the evevening) the plug ins on the camera were the exact same 3 prong so i thought that there was no reason why it wouldnt work. I pluged the 600mw 5.8 ghz transmitter into the power board. Pluged in my 3s lipo, and all of a suddon i heard a little pop and smoke was coming out of my 5.8 ghz transmitter. I have no idea why this happened and dont want to do the same mistake twice. Any advice will be greatly appreciated.
