The first thing to look at is the receiver antenna wire.
A lot of people getting into R/C underestimate the importance of this, which just looks like a bit of wire hanging out the side of the receiver box.
I'd also consider popping open the receiver box (if possible) and check the solder connection on the antenna wire.
(Oh, and one more thing - check your TX batteries)

- Never bundle up the antenna wire
- always have as long a straight run of antenna wire as possible (that's what the antenna tube is for)
- NEVER cut the antenna wire - it's a tuned length

fix
Make sure you don't use lipo's in the radio, if you think it works poorly now, wait until it catches fire.
Couple of things:
1) if the car chassis is graphite, get the antenna off the chassis (make sure it doesn't touch the chassis)
2) check the antenna wire for cuts, a cut wire will decrease range
3) check power to both radio and receiver

A radio is probably the best place for a lipo... lightweight... much longer lasting... low discharge rates and MOST guys are carefull with their radios

lipo in radios
I was just kidding, it was a rib at socalbomber. I run li-ion cells in my radio and wouldn't use anything else. I use 2 3.6v li-ion cells with a voltage regular and pcb protector for each cell. They are light and they have very little self discharge.
To Socal bomber, unless the antenna was shortened or cut, I wouldn't worry about making it longer. Just check it to make sure the wire is not broken. If you can, I would also try a different set of crystals in the radio.

Sure you can. All you need is a length of the same gauge wire the same length as the original antenna. It shouldn't be difficult to unsolder the end of the original wire and solder the new one in place.
While it may be possible to splice in a length of wire to return the existing antenna wire to its original length, this causes other issues, like leaving a lump in the wire which won't fit thru the antenna tube etc. It's much cleaner to replace the whole wire.
