NEU motor question

Yep!!! this is exactly the motor i have in my e-revo. But you should run it on 6s to have a good speed, and the MM can't take 6s. For the MMM, brushlessmonster.com have the MMM in stock ready for shipping right now

thanks for the help ...appreciate it
more noob questions....what is the difference between the 1515 /1.5 and 2.5 ? i realize it's the kv's but what does that actually mean in performance or laymen's terms ?? would the 2.5 be ok with 5s, with the MMM ??....thanks guys for dealing with all these noob questions
