I haven't had a glitch since I changed to 2.4 gHz a couple of years ago. I've flown everything from T-Rex 450 through Ion heli's and park flyer through 2 meter pattern birds with no problems.

Before switching to 2.4, I had issues in a couple of planes with high voltage BEC's and/or long servo leads....those were solved with chokes before 2.4 was available.
