It will be good to know if the motor fits ok.I had a quick look on www.one18th.com at the mini lst motor section and god talk about confuse yourself,everyone has a different opinion .Some say the insanes are great,some say they arnt.Loads say brushless but then loads have had problems with them.I was originaly thinking about going brushless but deffinatley staying brushed now.From what it sounds like if you go brushless you realy want to use lipo batteries and i am not to keen on them.Nearly had 2 blow up a couple of years ago with a heli i had so iwill stay with the ni-mh's .
