I've tried them all, M12 (too top heavy) KO Ex-KIY (Twitchy), DX4S, DX4R, 4pk, 4pks and now settled on a 4px, just on the look and feel although the trigger takes getting used to. Had an MT4, was a great radio the only radio I have ever had that I have truely thought was garbage was the Futaba 4pl/4pls.

Spektrum gear is popular, easy to set up and easy to trouble shoot because odds are someone at racing has one. But it has it's limitations they don't play nice with high draw servos such as Savox, the range isn't as good as some of the others and they are prone to interference from the coil on two stroke motors. Each to their own, find a radio you like not what people tell you to like.
