I thought the prices on this website looked to good to be true so i e-mailed traxxas directly and this was their reply. So pass it on this site is a scam.
People that scam people like that should be hung by their toenails in the town center, and people should be allowed to shoot them with bb's fired from slingshots until they stop wriggling.
I once purchased a discounted "TRX4" kit and received Thomas The Train stickers in the mail... luckily I used PayPal and was refunded and had to submit a fraud claim to the FBI
definitely fake, no hobbystore is stupid enough to put a $500 rig for $50.
EDIT
actually, if you read the privacy, return, terms and conditions policies, it is written as though it seems legit and real but the prices of the items throw it off so yea probably is fake
