Range distance

I have read MANY post by people that have glitching issues but it is usually with 20 feet or so or they have there antena too close to the ESC/Motor.

I am an airplane guy that just got into car racing. With a plane you do a range test around 50' or so with the antena down.

Is there a Range test with cars?

Approx how far is the effective range with a car controller?

I was getting about 75 to 100 feet with an AM radio so I bought an FM radio and get about the same range maybe 150 feet (with the antenna up).

On a side note I purchased a MX3S and it was glitchy at 20 feet so I sent it back and they retuned it and replaced some part and now get approx 150'.

How far does you setup go??

I forgot to mention this whole issue came up because when I am at the track there is a chain link fence and every time I get close to that it begins to get glitchy and I was told it was a range issue.
