Been out of it for a while. Now that I got my son a Slash I think I may do a little racing again. Doubtful I will be racing big events mostly just club racing. Now onto my ? I have an older Jr radio I think its the x3. It is still a crystal radio. Am I better off just biting the bullet and getting a new 2.4ghz? I was thinking of the m4/4pl/or 3pm-x. Is the 3pm-x as fast as the 4pk?
