Hey Mark, haven't even tried lap times since I added an extra 8 feet to the track.
When it was 191 feet (about a week ago) the record was 10.990 seconds with a Pro-Track Mercedes CLK lexan body on top of a Pro-Track 1/32nd scale "Spider" chassis. 29,000 rpm Slot-it motor, ball bearing bushings, carbon fiber axles,
and a 1/24th scale Parma "The Blade" guide. Oh, and 3 traction magnets.
I built some Pro-Track Spider chassis w/ Parma Super 16D Rotor Motors in them. Had to make all the motor mounts because the motor won't fit in the stock chassis. One car has a Fly Porsche 908/3 body on it and one has a Fly Porsche 917 body mounted on it. The cars are blistering faaaaassssssttttttttt, but heavy. They have 1" wide 7/8" diameter slicks out back. They had an intimate meeting with my garage door so they are getting rebuilt right now. They usually run about a second to a second and a half faster than the car that holds the record w/ carbon fiber axles. That car weighs only 64 grams.
I'm not familiar w/ Polistil track. I do know that Revell only made track from 1964 to 1966. That's it. The rights and the molds were eventually sold to a company called Riggen sometime in the late 1960's or early 1970's.
This is a shot from when the track was 154 feet long. Yeah I know the rotor motor car doesn't have a driver and the rear tires stick out a little, but so what. Personally, the tires don't bother me at all (that's what it took to get the Super 16D
to hook up good) and I can put a driver in there anytime. I just wanted to see
if I could take a Fly body and mount it on a better chassis and stuff a big motor inside. Kind of like something out of the Pro-Mod class at the drag races. Scale perfection was not the goal here. Going around 154 feet of track as fast as possible was. The car was AVERAGING about 18.5 feet per second.
Built this with my son for his science fair project to study magnets. It was the hit of the show. Track is portable, pre-wired w/ Parma controllers, and sets up in less than 1 minute. And it is adjustable from 0 to 90 degrees. Worked best at
about 82 degrees. You can race nearly straight up and down. It's bizarre but it works. Just add 2 rectangular slot-it bar magnets to your favorite Mustang or Camaro (they snap in place) and let it rip.
12.837 seconds. 199 feet. Each lane has 2 x-overs and 5 chicanes now. They're just temporary though.
Out of straights, but got 24 nice ones coming in the mail.
Car is a lexan bodied Mercedes CLK w/ a Pro-Track "Spider" chassis with a 29,000
rpm Slot-it motor, carbon fiber axles, and ball bearing bushings. Pro-Track front wheels and tires,
and Slot-it Large hub rear wheels + new Professor Motor slicks.
They really, really hook up and seem to be very durable. Used 1 rectangular Slot-it bar magnet
and two round neodyum Fly magnets to get the car to stick. All the magnets are stacked and sit
just in front of the rear axle.
Leave it pegged? Not at all. Not through any turns. Close, but not quite. Car
can let go in any corner. Wish I had 18V. The Professor Motor slicks just plain
Launched the car off of "Dead Mans Curve" again. 76" off the ground. That's
got to be pretty high in 1/32nd scale...... Picked it up off the concrete floor, put it on the track and ran it. Unbelievable..... Those Pro-Track "Spider" chassis really take a lot of abuse. Haven't broken one yet - even with the much heavier Rotor Motors in them.
