Servo action stutter from Core TX

[Boons]

Hi all,

Both myself and a friend have these radios and different servos and the servos seem to 'stutter' if you watch the action whilst turning slowly. We both have new servos. Is this a common issue with these? Some guys at the club suggested it's just because it's a cheap TX.

Is this normal for these radios? Incidentally lots of guys use the old KO radios at the club with the 2.4 conversions and swear by them, and their servo action is nice and smooth. If I am told that yes my radio isn't very good then I'll perhaps look at something like a Sanwa Gemini or others that you may suggest!

Sorry for the long winded post!
