Are there any other lap counting systems out there? I have not seen any systems work very well other than the Amb transponder type. I am not going to name names and bash products but there has to be some thing else out there. I recently heard about a system from Team_Orien. Supposedly it is a transponder with a optical output and Infared reciver. I could be wrong about the specs. But I would like to learn more about it. I am curious if this would work with mini-zs.

I am curious if this would work with mini-zs.I believe someone was talking about using this on Mini-Z. I've used them on 1/10 and they work well.

The team orian is a personal lap timing system. Only one car at a time.
I have one and used mine on my mini z when i was training for the nats in my basement. I removed the transponder from the aluminum case and taped it to the outside of the body with the IR led pointed to the outside wall.

Then you just set the pickup unit on the wall of the track. You have your self a counter.

amb-it $3000 - 4000
lapz $800
ko propo $2000
corespeeday $400
home made laser/flag system $400 (but a pain in the ass)
Hong kong IR counter (Bad software)
Paper and pencil ( very tough to use) :)

So far i have used every system but the lapz setup. Every system has problems. Amb-it does miss laps once in a while even in 12th scale. But for the money it should miss non. Kopropo uses the frequency of the car so for mini z you can't use any aftermarket 75 mhz radios. Home made counters are cool but the do miss laps or count more laps. Pain in the ass to align the lasers and if someone bumps the laser bridge it messes everything up.

We are currently using the core system (i know you guys are also) and last saturday we had 40 cars racing. All day we only had two lap miss counts and that was my fault. I set the min lap time to 4 seconds and the same guy was making it to the counter in under that min lap time on the first lap. Took me all day to figure this one out. hehe

And you cant beat the $2 transponders.

So does that mean that the KO system will count 27MHz FM? I don't see why it wouldn't, but that simplifies things for me. :P I love 27MHz vs. 75MHz. It's such a cleaner band.

If someone wants to buy a laser flag system off of me, you can make me an offer... It's this style: http://www.minizlapcounter.com for 6 cars...
It is not bad - but I am a big fan of internal antennas... always have been - always will be. Nothing throws the scale look off for me more than a gigantic antena that would be 9 feet long in scale length...

I don't know if it counts 27 FM. I like 27Mhz also but i have been to too many big 10th scale races and see an entire main with 27 band people........the guys who qualified 7-10 had to find 75Mhz radios to borrow.

40 and 29 for big races, but you risk being tagged by FCC. I always have a 75 module anyways.

As for 27FM, I can't see why it wouldn't count. I'll try it this weekend and report back.

I will try to, I went racing 1/10th sedans last Friday and got served. I am getting an HPI Pro4 tomorrow and may be working to get that going, also I may have to work my second job. If Scott is gonna show(as if there really is a way to be sure), I will be there to strongarm some stuff from him. If he does show up, bar the door and I will drop what I am doing.

nice that it uses amb transponders if you have them if not they are $80 or so....it also doesn't seem very east to take down and set up. core is still the winner for home and club use IMHO

Somewhat. The Lapz ones use irda transceivers like on a PDA or laptop. Mine uses led's and infrared receivers similar to a tv remote for a much stronger signal. The signal is also modulated for interference rejection. They can be programmed to any ID from 1-99 but only the first ten or twenty are supported by the AMB20 protocol that it emulates.
I don't have anything to weigh them with, but they should not affect the balance of the car and draw very little power.

It does not work with AMB transponders. It only sends the data to the PC in the same format as AMB20.

One of them is running 1/10 electric trucks, but he did not specify on or off road, just oval.

The scale is not really important.

If you run off-road, you would have to get a lot of mud on the windshield to affect it.

So you make an (i r) trasponder system which will work with a amb type software like (alycat). How much?

All the components are sold separately to fit individual needs. Check www.rclapcounter.com for pricing. If you email to the link there with how many transponders you need and how wide your track is at the start / finish line, I will quote the price for you.

I know at a few tracks for 10th scale off-road that some lap counters they can not use because the finsh line is right after a jump so you will be a couple feet in the air would your unit count if that happend?I know the AMB one does but i do not think the core system will.

The car must pass under a timing bridge that spans over the finish line. Obviously, you don't want to put it where the car might be airborne.

It does not seem to be too big a deal to move the finish line to a spot where the cars would be on or fairly close to the ground. I imagine this would be OK for the core system to work as well. A small concession to save a few thousand dollars.

If the off-road track was mine it would not be like that were the car gets airborne but thats what they are doing,how would the transponders connect to the car or do they?

The transponders mount with Velcro. They look throught the clear windshield of the body. They plug into the open slot on the receiver for power. On a mini-z, the power leads slide behind the battery holder terminals.

I've considered it and even have a box of appropriate cells.

The big problem is charging. I don't want to have to come up with a 6 to 10 unit "charging rack". It would also have to discharge them first to keep the batteries good as long as possible. This would also increase the price of the system considerably.

For years, everyone with the rechargeable AMB systems complained about having to charge them and the expense and hassle of replacing the batteries when they go flat or one goes dead during a race.

If a the battery were to go down during a race, no laps get counted. If it is powered by the car's battery through the BEC, it will work as long as the car can move.

There is also the issue of extra weight and its distribution on small cars like the mini-z.

I like the idea that it is a plug in transponder but some racers for 10th scale do not like that since it drains power, How much are the battery for them?

Then they should embrace the lack of a battery in the transponder.

I don't remember all the formulas, but I can confidently say that the less than 10 ma (10 ma x 5v = 1/20th of a watt) drawn by the transponder is only a fraction of the power required to accelerate the extra ounce or so along with the vehicle.

I don't think I am interested in supplying batteries, but if they really wanted to go that route, a 4 cell nimh pack around 120 mah should be available online for under $15. A small receiver pack with a female lead will plug directly into the transponder.
