no range w/ spektrum?

[t-maxxracer32]

hey guys for some reaosn my spektrum has a 20 foot radius untill it goes out of range. what could this be from? ive tried 2 different receivers and ive taken the remote apart. the antenna clips on to a peice inside the remote so i tried messing w/ it but nothing helped i even soldered the peices together instead of it being a clip and it didnt help.

anything else i could try?

thans!
