I've just receive mine from these guys.
so far, no glitching yet. I was only testing it inside my house and I also did a range test outside with my antenna down, about 100 feet before the receiver start to pick up some noise. it worked perfectly fine with antenna up.
I'm going to build a custom mini-z and a 18t if you want to know.
The receiver is Tune for 75MHZ FM ground freq, who use 4,6 and 8 channels you ask? the robot guys.
BTW I'm using a 3PK w/Synth
