one of th elocal race muckity Mucks here was preaching on it a few weeks ago....I was seriously looking at the EX-10 when I found it was in teh same price range as the 3PK....but I figured I like th eservo setup I have now and have since changed 3 of my RCs over to JR8611s and Futaba servos....no need to change what I already like now....the KO stuff does look pretty freakin impressive though...
