Im thinking of getting a Nitro off road truck. But not sure if I should get a moster truck or the stadium style trucks. I was just wondering what are some of the things I should consider when trying to pick from the two.

stadium trucks are primarily designed for racing on a bmx style track. They will usually be quicker, less expensive, and more manuverable.

Monster trucks are usually used for just bashing around in an empty lot, but have come into their own lately in sanctioned racing as well. They will usually be much larger, heavier, and a little slower - however, they have the ability to handle much rougher terrain and usually are a bit tougher too. They will usually cost as much as two times the price of a stadium truck though.

BTW, when he means slower, he means in a sense that the vehicle won't be as responsive as a stadium truck. Out of the box, some are as fast or faster than a stadium truck. I've own stadium trucks, 8th buggy, and a Monster truck, but my favorite offroad is the MT. They are just quick with even the stock motor and run over everything. They don't slow down a lot in the grass like a 2wd would or sometimes even an 8th buggy depending on setup. I purchased my MGT for $350 sale price last year. Right now my other offroads are collecting dust.

A MT is the moster truck I take it. Just asking cause HPI calls the one stadium truck the MT2.

lol
I have an HPI MT2 and i think it is kinda funny. A MT is a monster truck but HPI's MT and MT2 are stadium trucks.
Why??? Who knows.
Most stadium trucks are 2wd and all monster trucks are capable of 4wd. Think one was 2wd but havent heard much about that lately. Like mentioned before stadium trucks are cheaper than monster trucks. Stadium trucks come with small block engines and monster trucks either come with big blocks or can easily have one installed.
Other than that I guess it also depends on what kind of terrain you plan on running on. And how much you wanna spend.
