Not only is it not useful as a starting point (looks more like the start of a system to connect to the decoder, not an implementation of a decoder), you literally said this:

Here you go. Now you can make your own and it should even work with RC4.
Can't make your own with this and there's nothing here that'll help with the RC4 specifics.

Mylaps are a company and for them (like any other company) this is a business, not a hobby - and they are in it to make money (they have employees that need to eat, pay rent, feed their families, etc.). That's how our western capitalist system works - for good and for bad. It's not exactly their fault that they don't have competition on the market, is it? Plus, I'm not a hypocrite, so when it pisses me off (and it does!) when e.g. Chinese companies produce cheap (and mostly crappy) blatant copies of what western companies have invented and designed, regardless of copyrights and patents, I cannot turn around and say "Oh but it's different with Mylaps - there I support such a thing, because it makes my otherwise very expensive hobby slightly cheaper!" Sorry, no can do. Do I wish their products were cheaper? Of course! But I cannot dictate it to them.

And again, even at current prices, these transponders are IMHO only a rather minor cost compared to the rest of the equipment you need to race (and to keep racing!) that I don't see what the big problem is. Please think honestly about what you are ready and willing to pay for other electronics, the stock class motor of the month, all the tires, the bodies (depending on class)... and how much of these perish so quickly or can only be used in one class or one type of vehicle, while the single transponder you actually need is universal and will usually outlive them all. Yes, we all wish this hobby was cheaper, but that goes for every single component and all companies, not just Mylaps and their transponders!

Yes, of course competition is a good thing. So let other companies do their own complete products (without patent or copyright infringement) and then it'll be a fair competition. Because when the tech is apparently so simple, old and proven, how come no other company has ever done a serious effort to produce such a (complete!) system of their own (i.e. incl. a decoder!) in all these years? Should be a gold mine, right? With all those unhappy people that want to spend less money... There should be enough engineers out there that could do it, too - it's only tech, not magic. But for some reason, all that has happened so far, was to rip off the cheap and simple part, the transponders. Apparently it's much harder to build a decoder, right? Or is it too expensive to do? For whatever reason, to my knowledge nobody else has successfully built and properly marketed a complete working decoder / timing system so far. If MRT really is finally working on a decoder as well, that's great news! And it's about time someone does, after all these years, no, decades - it's almost 2024 now. Problem is, it might be too late by now. Almost all current race tracks have a very expensive Mylaps system and are not likely to buy a new one, unless they'd need to replace a defective unit, or the new system was much better (no idea what improvement that might be - after all, the Mylaps system does a good job) - but would a better system be necessarily cheaper?

I don’t think the issue here is stealing as the Chinese do, it’s more about monopoly, competition and compatibility.

Imagine if the only radio we could use was Sanwa.. that they owned the spreadspectrum signal and only sanwa receivers and servos could be used. The price for their systems will be very high and they would have no incentive to perhaps provide an entry level model.

This essentially is my laps. They have a closed system and MRT reverse engineered a device to work with it, and became the only competition. Mylaps updated their system to shut them out so there’s no competition. They also know very well. It’s not feasible for a track to have multiple timing systems so they have a monopoly on the market, and can command $100+ for a device that cost pennies to make.

I too heard MRT is making their own, unless it accepts my laps RC4 transponder's, it will be tough for it to get off the ground

I find it slightly ironic that some complain about a single$100 piece of equipment, that is effectively the “ticket” to participate in racing their $300 to $900 rc car.
Technically, it’s the cost of participation in organized racing. And you only need to pay it once per car. Average out per use, and the cost becomes insignificant.
Maybe some are forgetting the overall cost of the complete integrated system of software, loop, decoder, etc. How much is that?
That cost is almost entirely absorbed by the club or track facility. Where are the complaints about that?
I think some are taking for granted a system that works near flawlessly, keeps data accurately, times precisely, and helps organize so many people at so many events.
From that perspective, I’m thankful I only have to pay $100 to have the privilege of this technology and reliability.
I Use to race at a track where an employee had to hit number keys as cars wizzed by. Then a track where you were a numbskull if you forgot to put the transponder, the size of a micro servo, back in it charging dock after your heat. When personal transponders came out, it was glorious. I think complaining about what we have now is ignorant of how far it’s come and how good we have it.

Loop, roughly $200 depending on length.
Decoder, several grand.
Software, LiveTime is $30-$40 a month.

The objective of this thread, as I have understood from the start, is to offer a reasonably priced alternative to mYlaps transponders.
As this is a forum for sharing opinions;
I am of the opinion that the current mYlaps, and MRT products are already reasonably priced.
Yes, postulating that someone can simply pop one open and figure it out, or make a snap assessment that it is a rip off, is "lacking knowledge or awareness in general" as to what is actually involved.


revo_race 12-27-2023 03:39 PM

Complaining about what we have is totally different than complaining about a lack of options. I totally agree that we’re in a great spot. But I also think options would be even better. To simply stop pushing forward because we’re better off than we were 3 decades ago would be silly.

The cost associated with the facility, the timing system its utilities, et cetera are not directly born by the end-user. These fixed up start costs are partially covered by the fee that is charged for participating for that day for the class and additional classes..

I run a retail store, similarly to have such a business. You need a retail point of sale system, security cameras, security guards, cleaning crews. I don’t regularly have discussions with my patrons about what the cost of the systems that help me run this shop this nor, do I expect them to know what it is.

Back to transponders, I have actually paid the price to compete and paid the price of convenience by having 6 transponders in total for myself and my son. That’s a decision I made. I don’t expect it to be convenient for someone else or everybody else be able to afford it.

I still think the individual price for the transponders is too high. Overtime, the cost of many devices come down yet these have remained at the same level simply because there isn’t competition. Lets use servos as an example, metal gear servos were the new thing then came coreless, digital, brushless, high voltage, s-bus overtime. The older models prices dropped. The new versions of mylaps transponders are not offering any new features. They supplanted the older versions and made them obsolete to keep MRT out. It remains a simple, counting system. As a lack of competition, the price remains the same.

The transponders themselves are relatively simple. But the entire ecosystem is more complex. MyLaps still needs to support the decoders. They're a one time low volume purchase with no ongoing subscription costs. If MyLaps can't make money off the transponders then the whole system goes bankrupt.

Servos directly affect performance, transponders do not. There's an inventive for competition when the performance matters.

Simple, you are contradicting a Senior level engineer with a couple decades experience designing similar products. I’ll take his opinion over yours.


rccartips 12-27-2023 07:09 PM

I'm an EE. Our reverse engineering solution was to buy the I-laps system. We mount the transponder low on the chassis with no issues. And one of our guy makes his own PT for the I-laps and sells at half price :)

That approach requires everyone who already has a MyLaps transponder to switch. I-Laps also requires the IR loop to sit over the track which makes it harder to do permanent outdoor installations. That wouldn't fly with my local clubs, but it does lower the cost for clubs that can accommodate those disadvantages.

And I believe such a system would easily sell, even when not directly compatible with RC4, as the cost would be very little for new tracks and/or racers, and also no hindrance for existing racers - what is $25 more to spend in this money-pit of a hobby? Even established tracks might be interested at that price (if the system managed to become popular) and it might be possible to run in parallel with the Mylaps decoder on the same time keeping software (so transponders and decoders stay independent from each other, and only come together on the computer). The question is, would such low prices really work for a company to develop, produce and long-time support such products? Even in large numbers if it proves successful? I kinda doubt it. But it is what Mylaps has successfully done for a very long time, with their prices.

trust me, no company is going to give you deal on a product you can make money with and that company only gets that one time payment. remember, most electronics you're paying for the costs to develop the software not necessarily hardware itself. Just like any kit, the pricing is meant to cover manufacturing but also R&D work that was involved. Most of these products take yrs of development and investment before you can think of making any monies. Regardless, in this hobby you get what you pay for. You can buy knocks off that a particular manufacture has no idea what they're manufacture.

are you speculating or do you have access to mylaps financials?

My lap has been around for a very long time. If they are struggling financially, then it would serve their interest to diversify into other sectors and offer other products. MyLaps exists in 1:1 racing as well as RC. There are plenty of individuals entering these competitions every year and purchasing their equipment.

I personally think if they drop the price of their transponders from $100 to $50 more people would buy their transponders. I would probably have a dozen instead of six. Others who transfer the transponder between their cars would have multiples as well.

You don't need to tell me. I've defended Mylaps in this thread. As useless as it turned out to be...

Given how much we want more people to enter the hobby, shouldn’t the RC community be pushing for the Orange Lap version instead?

As mentioned several times, what is a 100 dollar investment for the next 10 years compared with all other costs you make on RC racing in 10 years time? I have my 1st RC4 hybrid from the 1st moment they had an exchange program and it is still working. I believe that is now about 15 years. Meanwhile I have about 6, 3 of them I bought as one package deal for just 60 euro on the used market. 20 euro per transponder was a good deal.
Also in 4 pages of talk in this topic I did never see someone mentioning the whole system behind it. You can create a free account at Speedhyves where every lap driven on a track with an online decoder is registered. The servers, maintenance and software development has also to be payed. But in the US tracks work with LiveRC where I believe you need to pay for a subscription?

I will admit I also have 2 mrt clones - the reason I bought them is because of absence of retro compatibility of the originals early transponders with the new loops. The newer loops don't see the old transponders... And that p!ssed me off. If I can't trust the original brand, then why would I bother... And the clubs are a set or making it a point to not upgrade the firmware....

​​​​​​I'm grateful to AMB/mylaps, still I think they started acting a bit too greedy at some point.

In a non-niche RC world, anti-trust authorities would step in btw.

The Bervoets that started Mylaps was the brother of the Bervoets that started Serpent, so not the same guy.

Regarding the update I agree that it could be friendlier for their customers but there is an exchange program to get a new transponder for a lower price. You can even swap an MRT transponder for an RC4 Mylaps. And can you blame them? They just want to secure their own design and market where companies like MRT are lifting on. Also MRT can not provide you an unique number that is your own with which you can create a Speedhyve account, you can only let them copy an original AMB/Mylaps transponder or else you get 20 selectable numbers that will give issues on larger races with more MRT users. This is one of the reasons some competitions only allow original Mylaps transponders.

I think the main and possibly the only reason why they have a monopoly and also why they are the go to for RC is because they have an already successful sustainable business supply timing equipment across all kinds of motorsport. I don't believe there is a big enough market within all motorsport including rc (which is a laughably small part) to run a second company that makes enough money and is not a passion project.

If Mercedes or Ferrari or Honda etc were to create an RC car it would not be the cheapest thing out there.

Lets be thankful that we have a reliable and almost fully adopted technology that allows us to travel all over the world to world class tracks or basement tracks or back of the barn tracks and compete with full timing and not a hand counter and a piece of paper with equipment we bring with us. Imagine if every track had a different system, What a nightmare that would be....

From a cost to racer point of view (this has been briefly covered earlier in the thread) 10 key ‘hand counting’ with numbers clearly affixed to the car is the way to go.

this is not to difficult to do but generally requires a second person in race control to count the laps. When i race directed back in the late 90’s we ran this way. The draw back is that laps could get missed if people got distracted.

for club racing the .5 second that can be missed with hand counting does not matter, larger events need the accuracy of the transponder loop.

the ease (as stated earlier) of the transponders counting laps is very nice for the race director.

to the original title of ‘is there a transponder hack’ nope (for all the reasons stated above.

i have heard from people i know who run/bike that there are ‘passive systems’ that are much cheaper for the individual (given out in the event bibs) but the counters are exponentially more expensive.

We hand counted for quite a while in our club. Our club was run by one of the nicest gentleman you could ever meet and his name was Dennis. You bought your "transponders" from him, he would sell you a set of 10 for $5 or so. They were puffy dots that you affixed to the outside of your car on the hood using the supplied velcro. You got 10 different colors and Dennis had his 10 computer keyboard number keys colored. He was amazing, I can't remember him ever missing a lap no matter how many people were running. He was affectionately referred to as Dennis and his Dots. But when we went to AMB, my OCD really kicked in because now I had a very accurate account of my lap times which allowed me to over analyze everything. :D

nielsm 01-04-2024 02:18 PM

The other system that is used by a few tracks and much cheaper is iLap. It is IR based. The decoder is a few hundred dollars and the transponders are about $35. Is it cheaper than MyLaps? Yes, on a per unit basis. But given it requires line of sight, mounting it in each car is more involved than a MyLaps transponder. My local track uses iLap, so I’ve got to have the transponder either mounted outside the body or through a windshield pointing straight up to be read properly. With MyLaps, I’d be more open to just using one transponder and move it between cars as I don’t need as critical a mounting setup. With iLap, I have transponders for each car since it’s too much of a pain to swap between and get them reading consistently. And if they are mounted on top of the body, they are more likely to be damaged and need to be replaced. So, is it really cheaper than MyLaps? No.

We had a learning curve with ilaps. Now we are able to mount the PT almost anywhere (low on the chassis, sometimes under the painted hood, usually in same location as amb/mylaps) and it will still read accurately. Maybe the key to ilaps is on how the readers on the overhead bracket are installed.

I cannot tell the difference if I have ilaps or mylaps/amb on my car :)

As a designer of the whole system they have the right to do that to rule out others copying transponders in a bad way. It is not nice but the step was already set over a decade ago with a transponder exchange program which still exists. Somehow people can complain about this one in more than a decade action but easilly buy new cars, radio equipment, motors and tires every year.

This is actually right in my wheel house. I ran a timing software company for about 17 years and we were a distributor for MyLaps, as well as others. We had about 1600 customers paying about $750/months for our software in 70 different countries. Go karts, motocross, full size race tracks, shit even the Nurburgring used us.

Across all of those sports, Mylaps was always the heavy hitter. It cost the most by a long shot but man was it reliable. It was also good over 300mph which most wouldn't touch. There's nothing particularly innovative about it until you get into the big money stuff, GPS tracking, having 20 loops on your track, automated light controls, a central server to track all the decoders and ancillary devices. None of that really matters to RC.

There are tons of other viable timing hardware companies. Tag Heuer, DeHaardt, Pixel, LapSnapper, Race Result, Apex, Alien RFID.... All of them work, none of them were as reliable as MyLaps. I can tell you from the millions of laps our customers logged we hardly ever got a support call from a MyLaps customer. But they're still over priced mainly because of the market penetration they have. No track is going to alienate themselves by not having a ML decoder onsite. The only one I would think would have a shot at eating into their market is the RFID guys. Xponders are seriously $2 a pop and they're a small sticker you slap on the car. They're super resilient too. Only downside is you need an over head gantry for the antenna, doable but not idea. But at $2 a piece you could just give them a sticker with their entry fee. With all that said, that's just the hardware, there's a ton of software to manage race days, registration, live timing over web sockets, scoreboards, top times, yada yada yada...

Aside from the radio every single item you mentioned is a wear and tear item, to which some would even argue the sensors do wear out. I actually don’t see many racers buying radios every year but even if they did they don’t have to buy a new radio for every car they own.

Radios wear out quicker than a transponder. Potentiometers don't last forever.

Where did I say radio's, I did say radio equipment. Every year a new car and with that for sure new servo's and maybe a new receiver and some even every year a new transponder.

I only complain about it because it made the amb house transponder set obsolete.

Those of us that are already into racing, $110 for a transponder doesn't seem terrible. But to a dad that want to try racing with his 2 kids on the weekends, it adds a huge expense.

I've got a couple ideas to solve the expensive transponder issue.


1. Build an open source decoder that will read mylaps transponders as well as open source transponders. Hardware cost could be brought down significantly.

2. Live time supports running multiple loops, will it support running 2 different decoders doing this? Could you run mylaps and trackmate at the same time?

3. Custom firmware for the mylaps decoders to open them back up to detect older transponders.

3 will be exceptionally hard. 1 has already been done. 2 might be viable, I've not tried.

For 3 there is no custom firmware needed, you only need V4.4 It is not possible to downgrade so you need to extract the actual firmware and upload it directly into the processor.

Thats....not how that works at all. Processor's inherently do not have any storage. Maybe some volatile cache, but thats moot. There's a boot loader that looks for the local image of the firmware on the ROM. If the bootloader or ROM image fail a checksum check, then it won't boot. The boot loader has a method for overwriting the current ROM, but it will check and make sure its incrementing the version number only. Your only hope would be to hex edit the old firmware and try to pass it off as an upgrade, but they have a few other checks they do to make this pretty much impossible. They are locked down pretty tight, understandably so.

I'm not sure exactly how Live Time integrates the timing feeds, our software could do this easily as we are just parsing the feed from the decoder to get Tx numbers and time stamps, thats all its really sending (there some other info like RSSI, but we just throw it away). So any software can easily just add a new parser to consume a new feed. Once those tx and times are in the software it doesn't matter where they originated from. A few of the companies we worked with even emulated MyLaps decoder feed just to make it easy on the software developers to integrate their product.

Their terminology was wrong but they're mostly correct. You can't just use their firmware update software and hand over the downgraded version. You need to do board level flashing manually. Either by desoldering the EEPROM and using a flashing tool directly, or using a special clamping jig to interface with the EEPROM in situ.
