RE: 2.4 Satisfaction Poll
No idea what the problem could be but I will mention that the zero signal off the tip of the antenna on these systems seems to be more pronounced than on the 72 Mhz. That is just based on chatter I have read.
Turning the antenna up so the side faces the plane is very important, again not based on personal experience but based on readings. I know there are three Spekturms in our club. Two DX6s and a DX7. They are being used to fly Easy Gliders/Easy Glider Electrics which we fly very high and far out and no one is having range problems. Two are using the AR6000 receivers with DX6 and one is using the AR7000 receiver.
