The 2.4 TQ system is pretty decent. You can pick it up on here or ebay for usually half of the price you are getting on Amazon.

Traxxas support will replace a bad 2.4 Ghz unit for $40, ($35 + $5 handling) so you can always get a used unit for dirt cheap and warranty swap it if there is something wrong with it.

They are good units, I get excellent range out of mine. It gets out of comfortable sight range before it gets out of signal range. It's certainly not a Futaba, but it's not priced like one, either.

They have stubby antennas, not the long radio antennas.
