| Hi jbon,
You don't say if the model is to be a car or if it's just for your own enjoyment.
If you want to race then you need to look at the links posted above, if just for one-off fun, then a monster truck style may be more appropriate.
Another thing, check out the height of the grass, it may sound odd but once it gets longer that 14mm the racer style buggies will slow down quite a lot compared to tarmac racing, this should not effect the monster trucks.
