Starting this comming Wednesday night, July23rd., My LeMans track will be apart of the Wednesday night series on a rotating basis with Toms' Stoney Brook. As usual the time for this will be from 7-9PM. Watch out for those massive speed bumps on Lone Tree Parkway near my house

This is a reminder that I have Slot it controllers (version 1.1) which have many more knobs than the standard Professor motor controllers (2 knobs). The main knobs that everyone should be concerned with are: 1. PT (Power Trim or Anti-Spin [Basicly a "refinement" of the Minimum Speed Knob): The PT knob sets the maximum accepted 'slope' for a power increase: if the power increase ratio is above this slope, the 'power trim' slope is applied instead. In other words: if the trigger is pulled sharply, the power increase ratio is very high: in this case, the power trim strategy releases the power to the car through a more gentle slope. In reality, a 'real' antispin should monitor the wheel speed and detect wheelspin before cutting back the power. This is not what this controller does, which is, instead, a 'smoothing out' of the trigger action. Actually, this idea is rooted in what was legal in the F1 rules in the 90s: real closed loop antispin being banned, this was as close as one could legally get. 2. MS (Minimun Speed [similar to the Professor Motor Minimum Speed knob]): (MS): this knob sets the starting speed of the car, i.e. the minimum voltage which is applied to the track, when the trigger is pulled just enough to leave the 'braking' area. Also known as sensitivity, in terms of a traditional resistor based controller, it is similar to changing the resistor's value, to get a faster or slower start point. 3. BK (Braking [similar to the Professor Motor Brake knob except that it has a "sweep mode" also): Braking occurs when the trigger is completely released. The braking knob selects between two different braking strategies: 'sweep' and 'fixed'. The braking dial is split in two halves: one, under the label 'sweep', puts the braking system in 'sweep' mode, the other half, under the label 'fixed', does the same but for the 'fixed', standard, mode. If you have ever looked at some telemetry data from a real racing car, you might have noticed that the deceleration peaks at the beginning of the braking (in a modern F1 car, deceleration can reach 5g), then decreases as the driver eases the pressure on the pedal, as he tries to match the car's speed to the desired entry speed for the next turn. This is what the 'sweep' braking strategy tries to accomplish: a strong initial braking followed by a gradual easing of the braking itself. In other words: the sweep always begins with 100% braking, then, gradually reduces it to 0 (zero), as time passes. When turned counterclockwise in the 'sweep' area, the knob position controls the sweep time, i.e. how long does it take to bring the braking from 100% to 0. Note that, when fully turned counterclockwise, the braking is fixed at 100%, or, if you like to put it this way, the time it takes to bring the braking to 0 is infinite. Apart from this position, the longest available sweep is 1.7s, and the shortest is 0.5s. The 'fixed' mode, clockwise, is the 'standard' mode of most, if not all, other controllers with adjustable braking: depending on the dial position, you get a stronger or weaker braking according to the knob settings.

Had a good turn-out last night . Thanks to all that could make it . Results: 1st- John 56.2 laps (with a little help from his brother ) 2nd- David 51.4 laps 3rd- Jim B 51.3 laps 4th- Jerry 48.9 laps (There's a turn there Jerry ) 5th- Mark 47.7 laps 6th- Jim N 45.2 laps I'll have to focus on building the "bridge" for the light sensors at the start/finish line to avoid the possibility of erroneously added laps from drivers marshalling their wrecked cars on the "White House" turn.

It was a lot of fun and the track is just amazing! Thanks again for having us Dave. Can't wait to run on it again.
