how long will the testing phase continue? when will it be available for limited pre order?

so far it looks very exciting!

still no email re: beta testing

I just got off the phone with Michael and CP MINI RC RACEWAY is going to be testing the Core Racing System hopefully by the end of his month.

I would have called, but there is no phone number listed and much of the website links to work-in-progress pages. My question or questions are...

Are optional sensors available to "sense" across a 100cm or 150cm wide track?

50 centimeter = 19.6850394 inch [international, U.S.]
100 centimeter = 39.3700787 inch [international, U.S.]
150 centimeter = 59.0551181 inch [international, U.S.]

If it is possible to time on a 3-wide RCP tile track, I may try it out.

TNB,

The track width is measured inside rail to inside rail which I think is about 34" for
a normal 2 tile wide setup. We haven't tried designing the system for wider
lane widths yet since it's taken a lot of time to just develope the basic system.
Hopefully, what we have so far is okay for most home users. We are working on
a larger scale system geared for larger track setups but that is a bit further down
the road.

Regards,
-- CoreAnalog

I guess everyone will have to slow down for the finish line. The larger set up should also appeal to those running 1/18th scales on an RCP Track several tiles wide.

one could not rig up 2 start finish line gates end to end under the mats? -- the code should supoort DUAL S/F line gates... then u can use them for larger RC cars... larger tracks.

Here are a couple pictures of the (1.8"x1.8") transponders, top and side views.
We also have (1.8"x3.0") transponders which have better pick up range. Both
easily fit inside the car. Here, I just attach it underneath the front windshield and
hood. The transponders have light adhesive on the backside which you can still
take off and adjust if needed. The transponders are also flexible and very thin.

Enjoy,

If they are flexible, does that also mean that the transponders can be angled or formed to a body though the transponder will not be flat?

TNB,

Yes, they are very forgiving and can flex quite a bit before the read range is affected. I usually have
mine stuck under the hood where they are angled and bent up a bit under the windshield.

That's what I was thinking since it would probably be better to mount the transponder as far as up front as possible for a quicker read, which would mean the mounting surface would not be as flat as it would if it were attached to the roof interior of the body. Myself, I would probably use velcro to mount it since I have a vast number of RCs.

What about what Draconious wrote to expand the capabilities of the system so that it may handle wider tracks?

Hehe build the transponder into mini-Z Bumpers cant get more upfront than that -- although they woudl have to be durrable hehe... or maybe slide into a pocket on a bumper... so if bumper breaks u replace the shell etc.. silly but just a thought... I think they should be BLACK if they go inside the car under the windshield... I will presuem painting them is ok? -- for cosmetic purposes... dark window with white behind it looks funky...


What concerns me is accuracy.... if they have a RANGE... then its not a direct LINE that they trigger on its an area near the reader... so is it at all possible that durring a near tie, a car that crosses first, could read as crossing after the other... asuming both cars are identical, and have transponder mounted in same spot?

I presume an ID can not be changed on the transponder? once its made? say some one makes two transponders.. puts one in the car, then another on another guys shoe.. and he "kicks" a ghost car acrosst he line to cheat? lol...

Could you test a worst case scenario: say some one makes an internal antenna for their Z... worste possible case is, the Z's antenna is wraped around the transponder lol... im curious if that would cause problems etc...

Drac,

You can paint/write whatever you want on the transponders. As far as accuracy, our time
resolution is about 5ms. So, if you have 2 cars crossing within 5/1000th of a sec either car
may end up being registered first. Assumming 10mph, the distance gap between the cars
is about 1inch (It's all a blurr to me anyways when it's that close). It would have to be a
judgement call since it also depends on where they mounted the tag. The ID's can only be
changed during the fabrication process. You'll never see a duplicate ID in your lifetime
(at least from the same manufacturer). We haven't tried the internal antennas in our tests.
We did have a transponder with the antenna going through the center and it worked
fine. I'm sure Arch2b or CP Mini Raceway will put the system to good test once they get
their system within the next couple of weeks.

Regards,
--Core
