2.4gig range?

[telboy]

What should the range be on a 2.4 spectrum unit?

I've just had my car out on the field and it only goes about 30/40ft away from me when the failsafe kicks in?

Now, I've got 11.1v in the tranny, cells are fully charged. I've run the speedo all winter without a problem along with the motor. I know indoors you don't go too far away from you, but it should got further than that shouldn't it?

I've tried a different receiver and it does the same.

any Ideas?
I've also taken the transponder out and it still does the same.
