New Decoder RC4 firmware, Transponder Trade In and 2018 price adjustments.
In November 2017 Mylaps announced an upgrade to the RC4 Decoder to support a new type of transponder developed for Drone Timing. While not a big market in Europe, Drone racing is big in the USA and Australia. To accommodate the new transponder, support for the RC2 transponder has been removed. RC2 transponders include the first Personal Direct Powered Transponders introduced in 2002 and replaced by the RC4 Hybrid (Harry) in 2009 and the Rechargeable Transponders introduced with the launch of the RC decoder in 2000 and discontinued in 2010. The MRT transponders are copies of the first Personal Direct Powered Transponders. The impact of this change is that any new RC4 Decoders, or RC4 Decoders that are returned for repair or upgrade will no longer work with DP, Rechargeable or MRT transponders. All Harry and Percy transponders will continue to work.

When the Harry Transponder was introduced in 2009 and the Percy Transponder was introduced in 2013 there was a trade in offer for DP, Rechargeable and MRT transponders for upgrade to Harry or Purcy  transponders. With this change to new RC4 Decoders we are offering the following trade in allowances on purchase of new Harry and Purcy Transponders.

  AMB DP or Rechargeable MRT
Harry 33 29
Purcy 28 25

If you would like to take advantage of this Trade In please follow the instructions here.

Finally this is the time of year that Mylaps review their pricing. The fall in the value of the pound against the Euro has continued and so transponder and cable prices have risen by about 7%.  11th January 2018

2017 price adjustments.
After the exchange rate dive after the Brexit vote we now have the annual MyLaps 2017 price adjustments, plus a bit more reduction in the value of the pound. We have held the prices for a couple of weeks as we often have a spike in transponder sales in early January. If there is any good news it is that the only rises are personal transponders. We have managed to keep clips, coax, decoder and other items at the previous prices.   18th January 2017

Brexit price adjustments.
Due to the adverse exchange rate since January and the sudden drop on the 24th June UK prices on Mylaps products will have to rise. For the last few years the gradual Mylaps price rises have been compensated by the gradual rise in Sterling against the Euro. I absorbed the drop in value of the Pound earlier in the year in the hope that after the Referendum a remain vote would restore the 2015 exchange rate. I did not want to increase prices then reduce them. Since the leave vote the value of the pound seems to have stabilised at about 16% below its value at the end of 2015. In the hope that the Pound will start to recover a bit in the Autumn I will not be increasing prices by 16%. It will be about 8% but that may mean another price increase later in the year if things don't improve. I'll be increasing the prices on August 1st so if you need anything or know anyone who does make sure they don't leave it too late. 25th July 2016

Office closed January 7th-26th 2016.
But mail order transponder sales via Paypal will be unaffected. Other items will be available from 27th January. 6th January 2016

Mylaps price increases January 2015.
As they do every January, Mylaps have revised (aka increased) their prices. This year it is around 3% but the Harry is increased by 10%. The reason for the 10% increase in the Harry is that after 4 years of generous incentives to clubs to upgrade to the RC4 Decoder, the Harry is considered 'old technology'. Because the Euro has weakened we can absorb these price increases with the exception of the Harry which is now 85, an increase of 3.6%. The price difference between the Harry and the Purcy is now 20. We have also slightly reduced the price for Purcy Multi Packs. 1st February 2015

Last chance to trade in an old PT for a Harry.
At the end of this year the trade in for a Harry will come to an end. We have been running this trade in since 2010 so there are probably not a lot left that want to upgrade. If you still have an old style AMB PT or an MRT then this is your last chance to upgrade. Stocks are limited and when they are gone they are gone. We will continue to offer a trade in for a new Purcy in 2014. 11th November 2013

Hello China!
Since 26th June we have been experiencing a very large bandwidth load from China, downloading the RC Boat software. This month alone it has been downloaded 8000 times! The download has now been disabled. If you want to download this software please email us for the link 18th July 2013

Sorry about the site outage last week
We had a long outage due to our service provider experiencing "problems". Sorry about that. We use Demon Internet and would strongly advise anyone looking for web hosting to steer well clear of them. Despite the site being out for a week they neglected to advise us we were down. Over the years their service has gradually got worse and they were recently taken over by Vodafone. We are planning to move this site to our other service provider. They email us with minutes of a site going down and generally have it restored within an hour or so. 18th July 2013

Special UK pricing of the Harry trade in is coming to an end.
In December last year the Harry new and trade in price increased but we negotiated a "rebate" for the UK until Easter 2013. That rebate has now come to an end so the UK price for new and trade in Harry is set to increase as soon as current stocks come to an end. Right now I have 90 available at the "old" price. Once these have been sold the prices will be:

New Harry 82
Trade in Harry 62

Multi pack prices for Harry will also increase. Purcy prices remain the same. Prices for other items are also changing in line with Mylaps 2013 pricing and reflect the current exchange rates. New decoders are up by 100. If you are thinking of trading in for a Harry or buying a new one don't delay. Postal prices have also changed in line with Royal Mail postal rate changes from 2nd April 2013. 2nd April 2013

Purcys in stock and lots of trade ins!
We now have a very limited stock of Purcy transponders, pictured on the left. Note the additional servo extension lead so you can wire the transponder into the main battery feed on an electric car to monitor voltage. It can also be connected to the receiver as previous transponders. Lots of people are trading in older AMB transponders and MRT transponders for Harrys and Purcys to future proof themselves in anticipation of RC4 Decoders becoming the norm. Middle picture is Trade Ins from EOS race in Germany last weekend, right is Trade ins from Finland received today.

The Harry transponder works with ALL Decoders, the Purcy just works with the RC4 Decoder. The MRT transponder does not work with the RC4 Decoder. 9th January  2013

RC4 Frequently Asked Questions
Here. 22nd December 2012

 RC4 Transponder available from the Mylaps RC Webshop
The Pure RC4 Transponder (Purcy) is now available from the Mylaps RC Webshop. You can also order Purcy with CarID based on your existing Harry transponder number. In addition you can also order Purcy with a 7 digit number of your choice, provided that number has not previously been used for an RC transponder. Click here for the Mylaps RC Webshop. Early in January you will be able to order Purcy transponders direct from us, but initially we will not be able to offer the CarID transponders or Custom Number Purcys. 22nd December 2012

RC4 Decoder testing at Rug Racers 2nd December 2012 Part 2
We did some testing at the Rug Racers event to check if the AMB and Mylaps Transponders were behaving at a race as they do in our bench tests. We compared the performance of the transponders detected by the RC4 Decoder and the RC2 Decoder used to time the event. Of particular interest were the number of "hits" detected. In simple terms the more "hits" the less likely a "missed count". The following table shows the average ratio of "hits" detected by the RC4 Decoder compared to the RC2 Decoder for the same transponder. the number in () is the total number of transponders of each type.

Decoder AMB Handout (2) AMB PT (15) Mylaps Harry (4)
RC2 1 1 1
RC4 1.5 1.5 3

The absolute number of "hits" for a particular transponder type varies from car to car, depending on the position of the transponder and the components around it. To work reliably the signal has to be detected as the car approaches, crosses and leaves the loop and the time and strength of each "hit" is used to calculate when the car crosses the loop. The more "hits" the better the accuracy. For each passing the number of hits will vary slightly. I have seen instances of the decoder getting less that 10 hits from some transponders and by moving the transponder to a better position the number of "hits" increases. If there are a low number of "hits" then sooner or later a lap will be missed.

To get an accurate time of crossing the loop the car needs to be moving quickly. That way the transponder is in one place (centre of the loop) for less time. Putting the loop in a slow part of the track was important when cars were manually counted but we haven't done that for over 20 years. The best place is on a fast part of the track where the cars can safely go flat out. Racing to the loop in a slow part of the track on the last lap of qualifying is dangerous for marshals.

As cars get faster and carbon fibre and to a lesser extend alloy is used in chassis material we need a "better" transponder signal. Both carbon fibre and alloy block the signal. More detail on this can be found here Why do Transponders miss laps?  Increasing the signal strength doesn't help as it results in transponder pickup over a wider area for cars with good mounting positions. This just creates more problems with cars being detected on other parts of the track. More "hits" generated and detected per unit time improves accuracy and reliability.

In addition to improvements in transponder performance for new and old AMB/Mylaps transponders RC4 includes the Pure RC4 transponder (Purcy). Purcy allows several transponders with the same 7 digit number but an extra unique ID number. In some types of RC racing it is permitted to use more than one chassis during an event, in others it is not. The extra ID number is there so the Timing System can detect if more than one transponder is used with the same 7 digit number. Without this it would be possible to fake results by using more than one transponder, one in the car and one placed near the loop. As the RC2 and RC3 firmware cannot report the Car ID (it was developed later), Car ID transponders only work with RC4 firmware. The RC4 decoder can be used with software that is not RC4 "aware". In this circumstance the decoder will ignore a second Purcy transponder with the same 7 number for a timeout period. This timeout period can be controlled in the RC4 Decoder by the timekeeper. 

RC4 Decoder testing at Rug Racers 2nd December 2012
We did some testing at the Rug Racers event to check if the MRT transponders were behaving at a race as they do in our bench tests. We connected an RC3 and RC4 Decoder to the loop that was being used to time the event. The event was timed using the older RC2 Decoder. The following table shows the % of passes recorded.

Decoder AMB Handout AMB PT Mylaps Harry MRT PTX MRT
RC2 100% 100% 100% 100% 100%
RC3 100% 100% 100% 100% 100%
RC4 100% 100% 100% 0-50% 0%

This demonstrates that all AMB/Mylaps transponders work reliably with the RC4 Decoders but MRT transponders do not, in fact only 1 in 5 PTX transponders recorded any laps at all. We have offered a trade in for MRT transponders in exchange for Harry transponders since April 2010 and continue to do so.2nd December 2012

RC4 Decoder update - important information
I'm expecting the Firmware Upgrade and Decoder Upgrades to be available before the end of November 2012. In anticipation here is some important information.
Firmware Upgrade (RC3 v4 and RC3 v5 Decoders)
You should be aware that the firmware upgrade is non revisable. Once the Decoder firmware is upgraded to RC4 you can't go back to the RC3 Firmware. All Mylaps and AMB RC transponders work equally well with the RC4 firmware and the Harry transponders will work significantly better with a doubling of the detected hits. This will be significant for cars with Carbon Fibre or Alloy Chassis. Purcy transponders will have the same performance advantage as Harrys but will ONLY work with RC4 Firmware. MRT Transponders are not compatible with RC4 firmware and missed laps will be experienced.
Decoder Upgrade (RC2 and RC3 v3 Decoders)
The New Decoder can not be connected to the PC with a simple USB lead. It has Serial and Network connectivity only. If you want to use the serial connection most laptops will need a USB to Serial Adapter. We can supply these for 25. The new decoder is significantly more sensitive that the RC2 Decoder. All AMB RC transponders will work significantly better with the new Decoder than the RC2 Decoder. Harry transponders will work better again with a further doubling of the detected hits. This will be significant for cars with Carbon Fibre or Alloy Chassis. Purcy transponders will have the same performance advantage as Harrys but will ONLY work with the RC4 Decoder. MRT Transponders are not compatible with the RC4 Decoder and missed laps will be experienced.

If you would like to reserve a Decoder Upgrade please contact us with the Serial Number of your RC2 or early RC3 Decoder and specify the number of bundled Purcys (up to 5) that you require at the special price of 45 each. We'll send you an order email to be returned with payment for the RC4 Decoder Upgrade (415) plus Purcys (cheque or transfer). As soon as we get your decoder we'll send it to you. Once you have the decoder please send your old Decoder. You won't be without a decoder while the upgrade takes place. Please note that the special decoder upgrade price is advertised by Mylaps as being valid until the end of December 2012. If you plan to upgrade your decoder but are not ready to swop just yet you can send payment before Christmas and we'll get the decoder in stock ready for you to upgrade. 19th November 2012

Transponder Upgrade offers
Since May 2010 we have been offering trad ins of the older AMB Personal Transponders and MRT Transponders for the Mylaps Harry Transponder. Details here. We can also offer trade ins of the RC Rechargeable Transponder for the Harry, contact us for details. 19th November 2012

Pure RC4 (Purcy) UK Pricing
Prices from January 1st 2013 are as follows:

  • Purcy without clip 65
  • Purcy x 3 with clips 194
  • Purcy x 6 with clips 378
  • Purcy x 10 with clips 612

We expect to have the Purcy on sale by the end of November from stock. Until the end of December prices will be approximately 5% less than the above list. While Purcys without CarID will be available from stock, if you require additional Purcys with the same 7 digit number these will be available to order. Purcy with Car ID 1-7 will be the same price as Purcy without Car ID. Please note that Purcy will ONLY work with RC4 firmware Decoders. When we feature Purcy on the sales page there will be a link to a list of Clubs who have RC4 firmware Decoders. Right now that list is empty.   12th November 2012

RC4 Decoder
The RC4 Decoder uses the same physical decoder as the latest RC3 Decoders with updated firmware. The Firmware update, expected to be available by the end of November, is a free download. To get the download you will have to register the Mac address and you will receive a program to run on your PC with the Decoder connected. This program updates the decoder. Full details of this process will be available soon.

If you have an older RC3 Decoder (purchased in 2006 or early 2007) or the previous RC Decoder you will have to upgrade the decoder. This will cost 415 including VAT and shipping in the UK. The updated Decoders are expected to be available in early December. If you upgrade your Decoder you will be able to purchase up to 5 Pure RC4 Transponders (Purcy) at 45 each.

If you have an RC3 Decoder purchased in 2006-2007 please email the Mac address to us and we'll advise if you need to update the Decoder. The Mac address is printed on the bottom or the decoder and starts EA: 00-04-B7-xx-xx-xx. If you can't read it you can display the Mac address of a powered RC3 Decoder on the LCD screen by pressing the left hand button twice. 1st November 2012

RC4 Firmware
The RC4 Hybrid Transponder (Harry) was release in December 2009. It has taken rather longer than was anticipated for the corresponding RC4 Firmware to become available for the Decoders but this is imminent.

The Harry transponder sends a mixture of RC2 and RC4 data packets. The RC2 data packets are used in the AMB PT and Rechargeable transponder. The RC4 packets, more numerous than the RC2 packets, include the voltage and temperature data. The Harry transponder sends a mixture of RC2 and RC4 data packets. The RC Decoder and RC3 Firmware only detect RC2 data packets. The RC4 Firmware can detect both RC2 and RC4 data packets, increasing the accuracy and reliability of the detection of the transponder. More data packets means less chance of a missed transponder and improved accuracy of the reported passing time.

The day before the BRCA 2012 AGM we demonstrated a comparison between the RC4 firmware and the previous RC3 firmware and older RC Decoders using a variety of transponders. The demonstration showed that the RC3 Decoder is significantly more sensitive that the older RC decoder for both AMB PT, AMB Rechargeable and Harry transponders. Comparing the RC3 and RC4 firmware the performance of the AMB PT and Rechargeable transponder remained the same but the Harry transponder performed significantly better with the RC4 firmware than the RC3 firmware because the RC4 firmware detects more data during the passing.

As more electronics is incorporated in race cars, both RC and full size, the electrical noise in the area around the cars is increasing. This presents a challenge for Mylaps to maintain and improve the reliability of timing data. The decoders used in RC are exactly the same as used in full size motorsport, only the firmware (software) is different. Developments in noise filtering and reduction has improved the reliability and accuracy of timing in full size motorsport and these developments have been incorporated in the RC4 firmware. Whilst this filtering has no adverse effects on AMB/Mylaps transponders the reliable use of non AMB/Mylaps timing components can not be guaranteed.

To summarise:

  • RC3/4 Decoders are significantly more sensitive that the earlier RC Decoder

  • AMB PT and Rechargeable transponders work equally well with RC3 and RC4 firmware

  • Harry transponders perform significantly better with RC4 firmware compared with RC3 firmware

As soon as RC4 firmware is available full instructions for the updating of Decoders will be available on this site. 29th October 2012

A new RC Transponder from Mylaps
Also demonstrated the day before the BRCA 2012 AGM was the Mylaps Pure RC4 transponder, nickname Purcy. This transponder builds on the functionality of the Harry transponder in two ways. Firstly it replaces the RC2 data packets with RC4 data packets, further improving reliability and accuracy. It also incorporates a CarID signal. This allows a driver to have a number of transponders with the same 7 digit number but an additional number 0-7. Timing software will be able to treat the transponders as being associated with the same car but crucially will be able to confirm that only a single transponder was used in a session to be absolutely certain that no false times could have been recorded by using an additional transponder outside the car.

It is important to be aware that the Purcy transponder can ONLY be detected by the RC4 Firmware and so it will not replace the Harry. If you have a Purcy it will NOT be detected by the RC Decoder and RC3 Decoder Firmware.  Exact price and availability of the Purcy is to be confirmed but price is anticipated to be approximately 10% cheaper than Harry. 29th October 2012

32 bits good, 64 bits not so good.
This Winter's marketing push for PCs looks like being 64 bit Windows 7. If you are using the AMBrc2 Decoder on USB you should be aware that the USB driver is 32 bit only. There is no 64 bit driver available. You can install and run bbkRC on Windows 7 both 32 and 64 bit but there are a few things you need to be aware of. Click here to download Installing bbkRC on Windows 7. For information about the USB driver and Windows 7 click here. Windows XP remains our firm favourite for running race control. If you have to run with 64 bit and the AMBrc2 Decoder then a USB to Serial adapter will help you out. You can still power the Decoder from the USB port. 7thNovemer 2010.

Time to change the clocks this weekend so it must be the BRCA AGM.
Upgrades are the message we will be taking to the AGM, plus the RC4 Decoder and Harry Transponder, plus some details of new software. Coming early next year will be bbkRC Shotgun, a simple backup timing utility that can run in a separate computer and log all transponder activity. Also in the pipeline is an iPhone App, bbkRClive. We will have early prototypes of these in action. We will also be talking about the MyLaps finish line camera and what it can do to make the results of close finishes beyond doubt. If you want to do an upgrade at the AGM, just bring along what you have and cash or a cheque book. I have one RC3/4 Decoder available for upgrade and lots of Harrys and Clips. A summary of the available upgrades is here.28thOctober 2010.



Harry goes boating! We are at Billing Aquadrome this weekend for the half hour British Championship.
Trade in your PT for a brand new Harry at Billing Aquadrome (near Northampton) this Sunday (26th September 2010). We will be testing the RC4 Decoder at the 1/2hr British Championship. We hope there won't be any incidents like this but a camera at the ready is always a good idea when there is any racing.23rdSeptember 2010.


Upgrade your PT to a Harry! Example of a trade in
We get trade in PTs in a variety of conditions. Here is one of the more extreme examples. "Thanks for the quick response, the Harry arrived just in time. My old pt got dislodged from its mounting point 1 lap from the end of the A final, I was running in 3rd so I went for the finish. I knew something was up as the car was handling funny. The pt turned out to be wrapped round the drive shaft and was rubbing on the wheel. Sorry it was in such bad shape. I used to use Velcro to mount old pt as I run 2 cars and needed to change it over often. The new clip system is much better". The clip system is the ideal way to move Harrys between cars. the clip can be screwed to the chassis and the Harrys will be safe. You can find a fact sheet about the RC4 and Harry Transponder here. To upgrade your AMB or Clone transponders to Harrys you should click here. 13th September 2010.

MyLaps Finish Line Camera earns its keep

At the Offroad Euros in Austria the MyLaps Finish line camera proved itself invaluable in confirming the result of the 2wd F Final. It also proved invaluable in confirming results where a transponder stopped working during a race. The Finish line camera can operate independently of the transponder, being triggered by the car crossing the line. It takes a bit of time to view the pictures, but it gives you an image and a timeline that is 100% accurate. A fact sheet is available here.
9th September 2010.

Upgrade your PT to a Harry! Trade in stocks are getting low!
We have just received our last allocation of Harrys for the trade in offer. If you are thinking about doing a trade in don't delay. Last month we traded over 100 Harrys at the Offroad Euros and we currently have only 150 Trade in units in stock. You can find a fact sheet about the RC4 and Harry Transponder here. To upgrade your AMB or Clone transponders to Harrys you should click here. Please do not send us transponders until you have completed the Upgrade form, paid and been asked to send us your transponders. Stocks of Harrys for new sales are high so no worries there.  9th September 2010.

Goodbye rechargeable transponder
The popularity of the RC4 Harry Transponder, combined with the mounting clip, has prompted the retirement of the handout rechargeable transponder. There is an exchange offer to replace rechargeable transponders and charge racks with Harrys and Clips. Contact us for details. 9th September 2010.

Harry sees Red
The LED in the Harry transponder has been changed. It is now always RED. One flash per second means it is OK, 5 flashes per second means it's temperature is less than 5c or the voltage is less than 3.5v or more than 12v. The reason for the change was that some people thought the green LED was yellow or orange. Be assured that as long as it is flashing, it is working! 1st March 2010.

A Double and Three Halves - Meet Harry!
This is Harry, full name MYLAPS RC4 Hybrid Direct Power Transponder. Double the output signal, about half the size and weight as the older RC2 transponder, operates on a wider voltage range (2.8-16v), has PTFE power cable, reports extra information back to race control and much cheaper than its predecessor. Lots of good stuff here. I can confirm Harrys work with the older RC Decoders and the previous Transponders and copies work with the RC4 Decoder. This is evolution, not revolution. Harrys will be available soon with a very special UK launch price. Click on the image for details. Over the next few weeks we will be taking Harry to some race meetings for you to try and buy at an even better price. Don't delay, the special price is only for a short time. We have 200 on order and it will be first come first served. Oh, just in case you wondered, there is a trade in offer on the "old" style transponder, and the clones as well. I would tell you the price, but you wouldn't believe me.
