OK, so I'm looking at getting my slash this week. I haven't seen anyone selling with a Spektrum or 2.4ghz system (are they the same thing btw?), so what I'm looking for is a cheap system. Any suggestions?

like anything else u get what u pay for, buy a cheap radio and in the future u'l likely want to upgrade, so wy not just get a better one right off? u don't need to spend a arm and leg to get a decent radio...a better radio just has more functions....I guess if all ur going to do is bash in the back yard a cheap radio is all u need, if u plan on racing by all means upgrade to a better one...what ever u decide the 2.4 is the way to go.... good luck.

I just bash and this is what I use.

Did you need to switch out the servos? Or basically just plug and play? Is that a radio made by Tower Hobbies?
Sorry for all the questions. Things have certainly changed in the past 20 years.

You don't need to buy new.. Look for someone who has purchased a RTR with a 2.4GHZ radio and swapped it out for their own radio.
The Losi ones can be had cheap and the new Traxxas ones also.
Many to choose from. Do the research to see what is out there and as always get the best you can afford. The older Spektrum DX3's ( square case) can be found for a good price in the swap and sell sections of a lot of sites and on Ebay.

2.4 G radio system is'nt exchange for all kind of manufacture,cheap radio system is recommended ESKY's 2.4G radio.

The Slash comes with a Traxxas radio system already installed. If all you do is bash, it will do the job. It is 27Mgz and that limits it to six channels. As long as there aren't several of you trying to use the same channel, you will be Ok. If you are going to buy the new four wheel drive Slash, it has the new Traxxas 2.4 system in it. Spektrum and Losi radios and receivers (2.4) are compatible. Futaba 2.4 is not compatible with Spektrum or Losi. I doubt that the new Traxxas 2.4 is equal to anyone else either.

You don't need to switch servos to work with a 2.4 radio. However some Futaba systems require digital servos if they are the FAST setup. That radio is made by Futaba.

wow lots of info... I'll be looking on the swap forum to see what i can find
