title_body: Unrecognised ESC motor connector I purchased an ESC and a Speed 400 motor about 17 years ago with the intention of building my first electric powered model plane. Life took its various turns though and my time for R/C modelling dried up soon afterwards. Now that I have 3 boys who are all starting to show interest in the area, I've started to find the time to look at it all again... yay!
  Part of the reason I never got to build that electric plane originally though was that I had no means of connecting the motor to the plug included on the ESC. I know I could just cut the plug and replace it, but I've been trying to identify the type of plug without success for a while now.
  Can anybody tell me what the type of the red plug in the image below is?
  
  As an aside, I'm a bit mystified by the battery connector, since it has 16 guage wires onto the ESC, but then connected to much smaller guage wires with a JST plug. I don't have any specs on the ESC itself unfortunately, so don't know what the rated current is and consequently whether or not I should be concerned about those wires!
upvoted_answer: I agree, it looks like a Micro Deans plug. They're good for about 10amps. A red JST plug is good for about 5amps. A speed 400 is pretty inefficient over about 5amps.
  Personally I'd junk both the ESC and motor and go brushless. You'll save weight, gain efficiency, be able to use a bigger prop and it won't wear out. And that ESC probably doesn't have a lipo-friendly low voltage cut-off.
