Test blocks for USD rule checking
Posted: Fri Apr 27, 2018 12:46 pm
Guys,
At last night's event we realised that the Scalextric track used for FRC's official USD test block, C7016 Scalextric Single Lane Half-straight 175mm, has rails that are slightly higher than the rails on regular Scalextric Sport two-lane sections. This means that if you do not use a C7016 single lane track section to test your cars, its possible that they may not pass the test when using a C7016.
At present four of the five regular racers use the 7016 for testing. Furthermore, with the already escalating speeds of the cars, going to a two-lane track section will allow more magnetic downforce with further potential for speed increases, something I prefer to avoid. Also, whereas the C7016 will allow cars to be tested with minimal to zero flexing, the 2-lane section will require reinforcing by attaching it to a rigid base. For these reasons I would like to suggest that we stick with the C7016 single lane as the standard for checking cars. I can easily update the FRC regulations to stipulate that this is the standard.
Whatever track section is used, at the end of the day, once everyone sets their cars with a standard track type, everyone has the potential to set up their cars to similar downforce specs.
