OK guys thanks for all the great advice. Icouldn't wait till morning so I got it running and ran 3 tanks through it. Definately getting more pep after each tank...the downside is is very cold here in CT and on the 3rd tank right before I was putting it away I nicked my fence at very low speed and it broke a plastic steering cross memeber.Are any parts interchangeable from other RC's and can I upgrade from plastic to anything stronger. Thanks again...Chris
