Default Need some advice

I want to get a radio for my Kyosho V one RR. I'm looking toward the JR xs3 radio. The problem is it costs about $240, but I found it on e-bay and online hobby shops for about $135-140, brand new. The problem is that they sell the JR xs3 radio in hobby for around $240 but they are 27 or 75mhz, but the other places with lower prices they sell them at $135-140 and the mhz is 27 or 40. What if i get it cheaper will the 40mhz work here in US? and also are there any cheaper prices?

Go with the 75mhz and NOT the 27mhz. Like KD said, the 40mhz is illiegal to use for r/c models in the US. If you're racing, the 75mhz will make your days at the track a little easier with 30 channels instead of 6 to choose from!

Well, if you do not race, 40MHz will save you money from buying too many crystals set. Since, it does not comply with ROAR, you'll have fun running your car the whole day with the slim chance of getting people on the same channel.

2 invalid points here:
1. the JR XS3 doen't use crystals, it's synthesized. So getting 30 channels over 6 is a BIG advantage because you don't need to buy crystals.

2. when we say that 40mhz. isn't legal we're not talking about ROAR legal, we;re talking about FCC legal. FCC is a federal governing body in the US. They only aloow 27 and 75 mhz radio operation for surface r/c models and 72 mhz for air r/c models.

I thought it was also against the law to even SELL 40 mhz r/c radios in the US but I'm not 100% sure about this!

You'll be safer to get the 75mhz. With all the offroad guys and the RTR guys, it'll be hard to really be on your own channel. Alot of the RTR's come with the 27mhz.

30 channels > 6 channels
