If you are just getting into scale trucks and the trailfinder2, these are some simple ways to improve your performance. There are lots of other tricks out there but these are what I personally use.

The hobby for me has really grown since the RC4wd Trailfinder2 came out. This is the rig I recommend if you are looking to get started in the hobby.
