RC Lap Timer/RC Lap Counter for RC cars. For personal training or for multi-user races in a club. Accurate, with wireless connection to your smartphone. Spoken lap times. It is fast and easy to set up. Get your unit for 99€. RC Scoring Pro; XRacer; RC4 Detection loop. RC4 Detection loops are embedded in the track’s surface at the start and finish line and at intermediate timing points along the track. A detection loop works as the system’s antenna. It picks up signals from the transponders and passes them through to the decoder.
Every RC vehicle has an RC transponder installed, that sends out a unique signal to the detection loop in the track. RC Transponders are small and lightweight and have been used in the world of RC racing for many years.
RC4 Transponders are available in different versions
- The regular RC4 Transponder gives insight into your lap times, connected voltage and ambient car temperature will improve your performance.
- The RC4 Hybrid Transponder is similar to an RC4 Transponder, but the Hybrid is compatible with older MYLAPS Timing Systems (RC4 Transponders only work when an RC4 Timing System is installed at the track)
The RC4 Pro Transponder
Live Time Rc Scoring Program
- It’s smaller, lighter and in all-black. Learn more about the new RC4 Pro Transponder!

Successful yacht classes and clubs sooner or later reach the point at which the number ofentries for an event exceeds the number that they feel comfortable accommodating in onerace and some form of heat system is needed. In Model Yachting Magazine Issue #134,published in 2003, there are three excellent articles describing the most commonly usedHeat Systems:
- Promotion/Relegation (Sometimes referred to as EORS, Equal Opportunity Racing System and now, officially, in its most up to date form as Heat Management System 2014 [HMS 2014], endorsed by ISAF Radio Sailing Division for international competition.)
- Odds-Evens
- Matrix Systems
At what point should a Regatta Committee consider splitting a fleet into heats? The answerprimarily depends on local conditions such as visibility, distance of marks from theskipper control area etc. However somewhere between 10 and 20 boats per heat will be apractical limit beyond which mark roundings become a nightmare for skippers and RaceCommittee alike. The actual maximum fleet size set affects each system differently. Forexample, if the fleet maximum is set at 15 boats, HMS will accommodate up to 27 boatsbefore requiring three heats whereas Odd-Even will accommodate up to 30 boats.
HMS 2014 (Promotion/Relegation)
Promotion/Relegation is a system in which after one or two seeding races the fleet isdivided into heats, A, B, C, D etc based on either total or lowest Race Scores and it isdetermined how many boats (x) will be promoted/relegated (x is usually 4 or 6). The lowestfleet heat is run first and the top x boats are not scored but stay on the water and racein the next higher heat. At the end of this heat x boats are promoted and x boats arerelegated and so on until the A fleet completes the race. The whole fleet is thus scoredfrom top to bottom.
This system is the international standard, available as a computer based system and isused by the IOM Class and several others. HMS 2014 is a simple update to HMS 2013 which hasa nice capability to produce .pdf versions of the score sheet at the push of a button if Excel 97 or later is used.The system is primarily designed for PC use and use on Maccomputers is not recommended. Whether the scoring is done manually or using a computer-basedsystem it is recommended that a Fleet Control Board is used to display and managethe heat promotion/relegation visually for all skippers to see. The principal currentsystem administrator is Henry Farley, UK ([email protected]).

Comments:
- Pro - Arguably the most rigorous in determining absolutely a top to bottom finishorder for each race. Can handle a large number of entrants if you are prepared to go tomulti-fleets (>2). The voluminous Instructions which cover a wide range of eventualities,while seemingly complex, in practice can be run quite smoothly. Skippers will sail againstskippers with a similar skill level.
- Con - The system procedures do modify RRS somewhat especially regarding handlingof protest and redress hearings which, if they potentially impact promotion or relegation,need to be dealt with promptly before the next heat can begin. It is possible for skipperswho find them selves 'on the bubble', continually being promoted and relegated, to sail asignificantly greater number of heats than skippers who predominantly stay in one fleet oranother which can be a burden.
Odd-Even System
This system, introduced from Europe in the early 2000’s was first used by the US LaserClass for the 2002 NCR and has since been adopted by the SeaWind Class as its favored heatsystem and used successfully in all NCR’s since 2007 and most Regional Championships. OurClub has used it for club events as well as major regattas. The system can be run quiteeasily in manual form but recently an excellent TWEAT (TWo-hEAT) computer scoring systemhas been developed by Carl Hansen ([email protected]) and used successfully at severalmajor regattas. The primary version TWEAT deals with two heats but a new version TWEAT ABcis now also available that can deal with one, two or three heats. The following documentsdescribe the current systems:

Comments:
- Pro - The manual system is very easy to run for small fleets using the specialscore-sheets. The line-up for each heat is called from the score sheet from the previousrace. The new TWEAT Excel scoring system has been used successfully now in several eventsalthough minor updates are still being made to improve functionality and ease of use.Printed line-up and scoring sheets for the next set of heats were ready for RD useapproximately 2 minutes after completion of the previous set of heats. The system shufflesthe fleet from top to bottom based on the previous heat placings so each heat has a fullrange of skipper experience. All level skippers get to compete against the best andbetween heats can watch some of their peers and learn from watching what the top skippersdo.
- Con - Skippers of different skill levels will be grouped together.
Pond-side computer scoring
Many clubs are afraid to trust pond-side computer scoring because of concerns about systemreliability, battery life, screen visibility issues, date entry errors etc. Both of theabove described systems have built-in verification safeguards to recognize and flag dataentry errors and take care of tie-breaking, discards and boats that withdraw or add in,after an event has begun, quite seamlessly.
While either system can be run using a laptop and manual score board, addition of a pondside printer can materially assist Race Committees with printed line-ups and score sheets.Printing and distributing a set of final score sheets to hand out to all skippers at theAwards Ceremony is a nice touch that skippers appreciate!System requirements:
- Laptop computer with Excel (ideally 1997 or later)
- Simple printer (B/W or preferably color) & paper
- 12v battery (hook-up to a conveniently situated car power outlet {max 100w!}orbattery or use a portable RV heavy duty battery)
- DC/AC inverter with cables and connectors for either car power outlet or direct toa battery. 2 AC outlets are desirable (Xantrex 851-0400 or - 0401 Power Plus 400W, $36-53is an excellent example.)
- Light shield box (wood or cardboard) capable of holding an open laptop with theopen end facing the operator and not facing direct sunlig
