<a href="http://www.rclapcounter.com/" target="_blank">I-Lap Timing Systems</a> is about to release a new "micro" version of its system's transponder units. The new units, pictured above on the right, are said to weigh half as much as the traditional ones (left).<br />

<br /><b>Chassis pre-installed with high performance brushless motor!</b><div>
<b><br /></b><div>
<b>Next generation MINI-Z introduces even more durability and power!</b><div>
<br /></div>
<div>
The next evolution of the MINI-Z Racer now incorporates the latest brushless motor technology into its performance. Never used before on a MINI-Z, this model includes the same-sized ‘Team Orion XSPEED VE’ brushless motor with its characteristic high durability, power, RPM and a flat torque feel. The MINI-Z takes full advantage of the brushless motor’s efficient low friction; non-contact properties that minimize wear and reduce electrical noise to deliver outstanding linear response and smooth acceleration for a sensorless brushless motor that is approved for use in the MINI-Z Cup and other official races. A limit applied to maximum RPM keeps the playing field level for all drivers. In addition, a newly designed circuit board with ICS function connects to a PC (adapter sold separately) for precision setting adjustments. Just download the ‘ICS VE Manager’ software from the Kyosho website to manage the brushless motor settings and remove the RPM limit to extract the full potential from your machine. The newly designed upper cover also allows simple mounting of the optional gyro on top and the chassis is equipped with the MR-03 ball diff that was previously optional. Now the MR-03’s dynamic performance is turbo-charged with brushless motor power to mark a new stage in the evolution of MINI-Z performance and technology.<div>

We just started a new Mini Cooper series, with strict stock regulation.<br />
<br />
The only allowed mods are: tires, bearings, t-bar (kyosho carbon only), and any body modification that doesn't affect exterior appearance (including modifying the original front body clip).<br />
<br />
After some flipping and rolling runs all cars are now manageable and competitive. Lap times are 15 to 20% higher than the track's fastest lap though.Unknownnoreply@blogger.com0tag:blogger.com,1999:blog-4261460113251326007.post-17141600611402962822011-11-28T02:38:00.001-02:002011-12-05T23:56:14.669-02:00New Venue, New Layout<div class="separator" style="clear: both; text-align: center;">

So I decided, just for fun, to run a CFD "virtual wind tunnel" simulation of a <b>broken</b> </span><span class="Apple-style-span" style="line-height: 18px;"><b>rear wing</b></span><span class="Apple-style-span" style="line-height: 18px;">.</span></span><br />

</span><span class="Apple-style-span" style="line-height: 18px;">The results were the following: the drag force recorded by the simulation while the car was "racing" at 10 m/s (36 km/h) was 6.4 gf. The down force recorded by the simulation at this speed was - 3.8 gf, that is, 3.8 gf of lift. </span></span></span>No significant lateral forces were measured, in spite of the asymmetric wing configuration.</div><div style="line-height: 18px; margin-bottom: 0px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"><span class="Apple-style-span" style="line-height: 18px;"><span class="Apple-style-span" style="font-family: inherit;"><span class="Apple-style-span" style="line-height: 18px;"><br />
