I have two corona 120 Helicopters, both are set up exactly the same with Mega 16/15/3 brushless motors, both have 3 cell 2100 mAh 11.1 volt Lipo batteries, both have Pheonix 35 Speed controls, and Both have brand new Airtronics VG400 4 channel radios, both have their antennas mounted in the same spot in the same way AND BOTH use Frequency #26, BUT, one helicopter flies fine and the other Helicopter gets lots of glitches and is very sensitive when you move the Rx anttenna around.

What is the reason that one heli gets glitches but the other don't, with identical set-ups ???????????[&:]
