I have never run any of these ESCs. I have heard amazing reviews about a few. I do plan on putting the 60A version in my TL01 paired with a MM 5700 and probably with a similar motor in my DF03. The 80A will do amazingly in your CRT.5 I would assume. I have personally not seen one though so I dont know about mounting it. Look at the size specs on it and measure where you will be mounting it. If it will fit then get it and run it. It is a deal with a BEC and fan all ready for up to 4s.
