Very nice builds, I especially like the '57 FORD. We used to employ the pin/tube mounting method back in the early 1980's running in commercial track series. After busting out the plastic on the rocker panels repeatedly, we switched to Velrco. All that was needed was a 1/4" wide piece of thin flat brass soldered to each side of the chassis, somewhere between 2-3" long, depending on the wheelbase. The Velcro allows the body to move and absorb much of the shock from collisions, whether they be with other cars or the wall. We typically run at speeds of up to 50 actual MPH on the commercial tracks with stock Parma Deathstar 16D motors, and with the cars weighing in at 175-200 grams, that really packs a wallop during some of the wrecks!
Another advantage of using the Velcro is not having to line up those four pins and tubes on each car, and it allows for for the body to be adjusted just a bit front to back or up and down during pit stops between heats. Quick swaps of a body from one chassis to another are possible, too, as we usually put the Velcro's "soft" side on the body for just that reason, the "hard" side seems to hold up better on the chassis, anyway. With many of the hard body racers at commercial tracks now using the Parma FCR 4" or 4 1/2" chassis, the interchangeability factor is even greater. We'll run a 10 week season with NASCAR "Cup" bodies (we've had a series with the truck bodies, too), switch to Musclecar bodies the next, Jalopies ('49-'57 American cars), Vintage Trans Am, single make Corvette or Ford GT spec races, ect., by just swapping the body and maybe adjusting the lead in the chassis a bit. My personal favorite class is the '58-'72 American intermediate and full size street car bodies with radiused wheel wells and 3 1/4" maximum track width (this can of course be tucked in to 3" on smaller tracks with tighter lane spacing). Also, these cars are required to run the stock plastic kit bumpers, no metal chassis mounted crash bars are permitted in these series.
I've still got some of my old stretched Womp chassis builds, both road race and oval track cars, and enjoy giving them a run every once in a while just for fun! Of course, at the lower speeds run on home and club tracks these type of chassis are just fine for competition, as you very well know, I'm sure! Some cool cars you've got in your stable, have fun building more and racing them!
Thanks for the photos... ENJOY!! -- Ernie :>)
