LapMonitor Lap Timer
 

Here's a thread for the LapMonitor lap timer. I bought one after seeing a local racer using one in the UK.

I've used it a couple of times so far, with the iOS app (Android also available) it worked really well. Easy to install and setup, brilliant if you have access to a track but no timing available. Having my lap times read out as I passed the sensor through the app was great, it's feedback I've never had when practising before.

LapMonitor is awesome
 

Purchased a lap monitor and this thing is awesome. It's similar to the old Orion transponder system because it registers lap times, but this thing is updated to 2017 specs that allow audio via Bluetooth and the ability to view lap times like the AMB system from your phone. Audio through my phone was okay since my buddies were relaying the lap times, but it might be best to use headphones for nitro.

This is probably one of the best driving accessories out there if you want to change your lines and know if that approach was faster or not. It's also good to know how consistent you are and figure out the limit of your setup and find out what happens to your time if you push too much.

Setup was pretty simple, I have it connected to my android phone and so far no issues. When we tested it at HotRod Hobbies, I had the lapmonitor approx up to 4 ft from the transponder and it registered each time. You can power the transponder through your receiver or from an external power source. For my first outing, I used an external battery and cut out a piece of carbon fiber so I have a base that is velcroed to the window. If you create a mounting base, I suggest using double sided tape on the battery opposed to velcro since it was dangling after every other run or so.

That being said, wish I had this in my early days of RC.

Solutions like this come and go from time to time. I guess my big question would be able the availability and future roadmap.

It is already available on lapmonitor.com website. Our roadmap is to keep on providing an easy to use, accurate lap timer for practice and multi-user races in your backyard track or within a club

Bumping this up, as it is relevant to all the current club racing going on, and is a great alternative to MYLAPS!!!

I'm looking to pickup this system soon, looks great!

Ive been using this system for quite a while now, and honestly it's one of the best timing system out there, easy to use.

Glad to hear that, any issues with sun light causing missed laps? Are you able to adjust how sensitive the IR is on the lap counter?

LapMonitor is successfully used in Turkey to time 1:8 nitro and brushless national championship and it is a very sunny country
Sun can slightly reduce the range (mainly if facing sun at sunset or sunrise) but it works well under sunny conditions
If you notice any miss lap, you can easily change LapMonitor location on the track to keep on getting good detection as LapMonitor has a long bluetooth range

Just ordered one of these systems and am so stoked to have them for our practice days! All the tracks we practice at locally in the Pacific Northwest don't have lap timing systems, so this rad little system should really take things to the next level :D

You won't be disappointed with this timer. It's so helpful on the track, I use it to manage a Mini M05 series. Everyone is happy with it

Is there any way for me to buy it locally in the US or is it only available in France?

Thanks.

Only available in France. Easy to deal with them directly, no issues.

Do any other transponders work with this system?

Rich

No, only their transponders.

I was hoping.

How much in U.S. dollars, would it cost for the timing system, each additional transponder, and shipping to the U.S. ?

Thanks for the post. I have a nice backyard track and use a phone app that will record and broadcast via bluetooth one car at a time on track. My racing has improved dramatically since finding that app, to the point I also now keep excel spreadsheets to track my laps, fast laps, average laps, efficiency, and standard deviation of all my practice time. I've been looking for an affordable way to add competition (more cars) to the practices, and this looks like it may be it. I'll be checking this out for sure :)

Today there was a post on lapmonitor's facebook regarding differences of 1/100 sec which reminded me that when I tested it, for the local track, this effect was way bigger (tested by checking at the two extremes of the track's width when the car was detected).

Anyone knows if this is somehow handled by the software or hardware? I don't care, at all, it's a fantastic product, I'd just like to be able to now what is a significant difference and what is car placement between laps, and of course over multiple laps this will average out.

Hi, thanks for explaining this case, indeed when car path when passing the lap counter is very different between two passes (your drawing is showing the worst case) then accuracy is worse than few 1/100s .
But this is not the normal use case of racer who is battling for a 1/100s .The error in this case is dependent of the speed, the faster the car goes the better is the accuracy, for example a car at passing the lap counter at 40km/h and a lap with 2 passes separated by 2 meters you can get an expected error of 6/100s
Also this error is not cumulative and will be canceled at next lap when going back on the common car path of the driver.
We tested on a track and compared to video timestamp and error was few 1/100 secs differences (usually less than 2-3/100s) you can check it on some of our youtube video
This can be improved with software but not yet implemented in our software but as I wrote above the case you describe is not the normal use case when you're doing your best laps and as you wrote and expect the next lap this error is automatically corrected

I've been using Lap Monitor for a few months now. The Lap Monitor is within 1 to 3/100 secs of My Laps. A lot of my buddies use Lap Monitor and all have had great experiences out of it. It's a great tool to have at the track.

Your going to love this timing device. ;)

How much did that cost with shipping? If you don't care to answer, that's cool too.

I've been using LapMonitor for about 6 months now... absolutely love it when I spend time at the track and the track timing is off. I run it on 3 of our vehicles and monitor with the Android app. Huge fan. :D

Hi Billy,

Less than 3 feet is an unexpected very small range. Was the transponder facing a painted body area ?
To get good range the transponder must be in front of a clear body area like the window or a hole
Could you post a picture of your transponder install ?

Thanks,
Franck
