johndias Posted June 19, 2018 Author Share Posted June 19, 2018 Well, I've replaced the cap and broke the pot down and cleaned it with alcohol (it was just a little dirty). I tested the pot and only got 462k ohm. The result is the same, around +5.7 on the pot output. I bought another 400 from ebay and when it comes in I'll try out the CPU board to see what I can do. Very frustrating! But, thanks everyone for the help and instruction. Quote Link to comment Share on other sites More sharing options...
johndias Posted June 22, 2018 Author Share Posted June 22, 2018 Success! Well, kind of. I bought a non-working 400 from ebay (which turned out to be working) and swapped the CPU board... color is fine. I guess the pot was the bad part? I will fiddle with it more to try and narrow it down but for now, my UAV is looking good! 2 Quote Link to comment Share on other sites More sharing options...
