I Have A few questions about some of the cars..
Do HPI make A 30cc engine For The Baja?
What Would Be The Best Radio For The Baja?
What Would Be The Best Radio For The Hellfire?
What Would Be The Best Radio For The RS4?
What Would Be The Best Radio For The MT2?

If anyone Has Another sugestion For A new Onroad Or Offroad RC id apreciat for you to say

There are more companies than just HPI. I'm not saying HPI is bad, I like HPI. Look into a revo maybe. You have much more options then HPI. It is all personal taste. I think the Hellfire, although it looks badas, is overpriced. Out of those I personally would get the baja. I also like regular savages, the XL is overrated imo. This is all personal preference.

get the Baja 5B! yiou wont ever get bored of it.

Get a nomadio react for a radio, there awsome!

Id say go with an on-road car to compliment your off road Monster truck...that way you can have the best of both worlds. For all of your vehicles, I recommend a spektrum radio either the 2.0 or 3.0...they are about the cheapest 2.4ghz radio and imo the best bang for the buck.
