i just got myself a troy built monte park flyer. i saw one of these things hangin on the prop and can't get my hands on one fast enough. anyways my questions are endless. can someone explain to me th difference between an outrunner motor and an inrunner? whats the deal with the li-po high discharge is what your lookin for batteries or something? also what is this Kv stuff? is it the higher the Kv the better? i was looking at one motor the himax 400 and it comes in the 720Kv and the 920Kv or something for the same price and it also comes in a like 4200Kv or someting. also between mounting these motors whats the options. i am just really lost being new to this park flying. looks really fun but i really need to understand it before i get flying! thanks
