i have one of the original nikko scorpions, the yellow one i think it was the first versoin, have you seen that black phantom truck by radio shack on ebay? same truck as the scorpion 2 but radio shacks version, i had both versions when i was a kid and the black phantom seam to have more balls than the scorpion 2,
the 7.2 scorpion really isnt much faster than the 9.6 version but i guess it gets around in the grass
