LapMonitor Timing System

Having grown tired of my old practice lap timing system, I wanted something new that worked together with my phone. After some research, the product that appealed most to me was the LapMonitor Training kit.

I decided to order one of these, as live laptiming is not available on all tracks, and doing any useful testing is impossible without a reliable timing system.

Here are some key features advertised by LapMonitor:

  • Multi-user lap-timer for RC cars and motorbike
  • Accurate and easy to use
  • Start a race or a training in less than 2 minutes
  • FREE Android and IOS application
  • Multi-language (FR, DE, EN, IT, SP, PT)
  • Spoken Lap-times, live race commentary
  • Share, export your results
  • Wireless, range up to 80m
  • Low power, up to 150 hours race time with 2xAAA Batteries
  • Designed and made in France

As I mentioned already, the key for me was the Android app, with the spoken lap times also a welcome feature when testing things on track.

My order arrived super quick, and the support from LapMonitor was very good from the start.

Let’s then take a look at what you get in the training kit. Different versions are available in the LapMonitor shop.

The kit comes in this simple box.

With the different items placed in separate compartments.

Here in the picture below you see the full contents of the LapMonitor Training Kit (JR).

As listed on the LapMonitor site, these are:

  • 1 LapMonitor
  • 1 Support
  • 1 Tripod
  • 1 Transponder with JR connector
  • 1 Male-female 15 cm JR extension

In addition, in the kit received were these items:

  • Another different tripod
  • 2 x AAA batteries for the LapMonitor
  • Sticker + some small accessories

A closer look at the transponder.

The transponder weighs 6g, and measures 25x16x10mm, and is very easy to mount due to its shape. The transponders are obviously available separately as well.

Here, the LapMonitor unit is held by the support, then mounted to the smaller tripod, in the way you place it beside the track you’re driving on. The unit is powered by the two small AAA size batteries included, and turned on by bluetooth from the app on your phone.

I received my LapMonitor just as I was to leave for a testing session at a track far away, so I had no real time to get familiar with it before the test. This was not a problem though, as the app and timing system is super easy to use. The system also worked reliably throughout the day with no problems, so it very much did what it was supposed to do.

As far as I understand, LapMonitor is a very small one-man project. There are for sure lots of features that can be added and fine tuned to make the product even better. But that’s the great thing about a product like this; The fact that the app can be updated (and is being updated) constantly with more new features and improvements through user feedback.

Overall a very positive experience, and I will continue to use the LapMonitor whenever I go testing on a track with no live timing.

New Mugen MTC1 Option Parts

Great to see this activity from Mugen on the MTC1 project, with some much wanted new parts.

A2230-B  Diff. Gear (H.D.)

The new HD differential gears are made with a new material to improve the durability.

This allows the differential operating smooth over a long period of time and keeping the oil in the differential clean.

mtc1_A2230-B

A2234  S5 Soft O-Ring (Red 50°)

This is a set of ten S5 Soft differential O-rings, are intended for use with MTC1.
These O-Rings are used as seals on the differential outdrive.
Since the differential operates more smoothly from the early stage or
from the extremely slight operation, the new soft o-ring allows more smooth
direction change at corner entry and improves the stability at corner exit.

A2523  SP3 Soft O-Ring (Red 50°)

This is a set of ten P3 Soft Shock O-rings, are intended for use with the MTC1.
Since the suspension moves more smoothly from a very small amount of
movement, this allows reducing the friction of the shocks and improves the
stability in corners.

A2309  Steering Collar

This is aluminum collar for connecting A2301 (steering shaft) and A2307 (Servo plate).

Improves the steering response at high grip carpet track and stability at the place where the road surface is undulated.
Note: The steering may decrease if the grip of the track is not enough.
