I have that same truck it is the first nitro I started with it is now 3 years old on the same engine and rips it will beat a jato 2.5 across the grass but my friend bought one and it did the samething and he took it back to the hobbyshop and asked them to call losi and they gave him a new truck on the spot and the LHS just sent the old one back. when you tried it again did it not start or not roll over?
