ESC just warm.... check
Motor able to touch for 3-5 seconds....check
Super speed....check


From the sounds of it your good now. Unless you have some type of condition that prevents your fingertips from detecting heat your esc and motor seem to be fine. I think you've answered your own question. Unless there is something wrong with the speed or running time that your getting?

I've found that being able to touch it for 3 seconds or so usually means its at about 135-140 so, so you should be fine. Here's a temp gun review: http://www.modelkits.com/radio-contr...er-review.html
