actually I just put my fast trax into a storage container 6 months ago, to make way for the hobby grade RC's, it was still in fairly good shape with the original threads.
Other things that joined it the Tyco truck that shot 5 darts, the one that shot water, 2 of the Tyco Lamborghini's (think I fried em) from the late 80's early 90's, a bandit in almost new shape with the extra 2 battery compartment, and a few others. Yes I had lots of Tyco RC's when I was age 10-15 or so
.
If I knew about the hobby grade ones I would have probably started back then.
