It may have been posted earlier but is there an offical zero gravity tech tool? I thought I saw one for sale but cannot remember who, where, what? :?

We like to think of them as a zero magnet tool and save the zero gravity for outer space. :D

Joel,
Thank You for the photo. The track is now together and wired but the driver stations have not been installed. Last week I was able to hook a controller up with alligator clips and took a T-jet and G-Jet around the track for quite a few laps. The track is pretty smooth and the cars run well with stock pick up shoes. The Nantasket Beach Race Club is scheduled to race a Wednesday night at Lenjet sometime in March. I'll ask John Reimels to bring some of his Bass War cars with him for testing.

Ron is preparing to paint the lane colors and install and wire the driver stations. As of this writing it appears that the driver stations will be finished in Formica. Were also measuring the exterior walls in lexan. I'm not sure of the color of the walls or the interior infield. Once the lane colors have been painted on the track we'll make those decisions.

Peter has been promising some photos as it now lays. Maybe he's waiteing for the lane colors to be painted on the track before he places some photos on this site. I'll make another request for him to send some photos. Thank You.

Cool picture! How big would you say the jump section is?

Neo,
I'm not sure how long the distant is for each tap since I didn't wire it. There is a short dead (original) section for the lap counter which means that we must have two taps. I'm guessing that Ron has checked out the amps and volts readings around the track. I'm pretty sure Ron is back Tuesday to start wiring the driver stations. I'll ask him the same question. Thank You.

Since the ski jump is no longer available, I can't say. All I know is that I fell off the jump every time I tried it. lol

Real sports and formula racing cars are built to come in below the minimum weight allowed by the rules. They then add ballast, lead or tungsten into the area under below where the driver legs are to get up to the legal weight. They can move the the ballast forward and back to tune the handling.
I read about this long ago in Racecar Engineering magazine long ago. The Idea of getting the mass as low as possible and to the center is very interesting. But cars that steer and little ones that follow a slot are very different.
We shall see!

Quick question...
Will gravity class legal ...lift test-passed cars work with reed switches for lap counting?
Thanks

Ryan-- I would say No. We ran light bars on the tracks this year for gravity.

Reed switches work fine for Fray style T-Jets and one of their requirements for several years was that they would not pick up a pin. :shock:

I was at an ECHORS event in March where the race officials had to eliminate the totals on one of the lanes because some of the T jets weren't counting with the reed switch lap counter system.

All you need to do to activate a reed switch lap counter is place a small NEO mag behind the guide pin and on the centerline and not over the rail.
This is what I have done on Mark McVittii s track and it works nicely. I do a lot of testing there and I just stick a traction magnet from a ROKAR on the guide pin. It works well.

Not all reed switches are created equal. If you are having trouble tripping the reed, swap out the reed for one with greater sensitivity.
