Thanks for all your answers!

Mayhem Maniac: I have not considered the Revo or LST since I do not think I want a monster truck. One problem with the MP 7.5 is that it often rolls over when turning on grass, think that a monster truck would do it even more than the MP7.5? The Hellfire seems to be wide and low which would be good.

We will not buy the cars until april because of the winter in Sweden, then we will perhaps have some more opinions on the Hellfire.
