ok thanks, now for my next question. How do you determine what capacitors to use on a motor? Reason I ask is because I had a very nasty crash into pavement the other day and have broke one of them off of my motor. I have thousands of these things in my storage that I got from a radio shack pallet not too long ago so I just need to know which ones to use. I would be replacing them on the stock 480 motor on the hobbyzone super cub.
