If you are new to nitro power. It is better to start from 1/8 scale. Not so many area to tune ( you can forget the front differential or spool and rear differential ). The price for the engine can be lower and more easy to tune ( better to start with Novarossi base engine as it is more easy to tune but normally more expansive. If you want a Picco base engine. It is better to start with REDS as it was design by Mario Rossi, it should have the similar characteristic ). Only the same shore hardness for the tyre ( Front 32, Rear 35 ). Larger contact patch so that the traction is better and more easy to drive.
