        Controllers

        It is important to note that we did some controller testing and using Ohms Law, we proved it is impossible to have a linear controller. You see, a slot car motor's resistance is very dynamic, depending on the speed on the motor. Hence, it would be impossible to match the resistance in a motor in order to have a linear controller. There would always be some sort of non linear step at the end of the resistor swing, right before full throttle. I would like to thank both Doctors, Rich and Robert for helping to prove this theory. I would also like to thank Mongo for being our test subject. Did anyone mention where all of the controllers are plugged into?

          Skill vs. Skill (El Mongo vs. El Segundo)

          Rumor has it El Mongo is going to challenge El Segundo to a "skill vs. skill" competition. As you can see, El Mongo has linear, non-linear, anti-linear, quasi-linear, pseudo linear, reverse linear, exponential linear, part-time linear, full-time linear, sort-of linear and spinear-linear controllers at his disposal. Some folks claim he carries a spare non-linear controller in his boot and another one under the Sombrero for emergencies. With all those heat sinks, El Mongo is one "cool" customer.

          This competition will be strictly a test of driver skill (no electronics whatsoever) - whoever can carry the most non-linear controllers wins (those heat sinks get heavy...).

It did have a ton of straight line speed.
            Thanks for piloting my ride, Mike. I'm sure you got the most out of it you could. Thanks as well to the area 51 crew for bringing all the GPR cars to the finish line. Congrats to the podium guys, and everyone who made the trek around the world...er...globe.

              Hello

              First of all I'm delighted that my car raced so well, finishing joint 10th in the prototype class, after qualifying well down in 18th place.
              Secondly, I've really enjoyed following this series around the World so well done to all the circuit hosts, racers and reporters. This was my first ever proxy entry and its been really great .

                thumbs up to all!

                Kudos to car builders and car drivers! El Mongo Nino should be on a Post Office wall somewhere? Mcmannix.

                  You could hear El Mongo yell as he rode away in a cloud of dust after the proxy race in his trusty silver steed called Subaru! HI-HO! linear controllers!

                    His picture was in our PO on the most wanted board. It kept scaring the city carriers so the pic was taken down. He has a warrant outstanding in Iowa for selling black market linear controllers to an undercover corn bear.

                    What in the world is a matter with that 917k of mine? Are the front wheels still pressed on too far not letting them turn freely? Just curious.

                    • Stop thinking like a no-mag racer! The only thing wrong with your 917K (which I practiced with for a while) was that the magnetic downforce is light, and it is at the front of the chassis, right behind the guide. The car had to be driven like a no-magnet car, and if it slid in the turns, it was lost. You could loop it into a tail-out skid, but the cornering speed dropped off drastically, as there was only the unmagnetic tire adhesion pushing it around the curve. Magnet cars tend to go remarkably fast in the corners, and surprisingly slow down the straights. The magnet on the 917K should have been wider, stronger, and well to the rear.

                      I specifically picked you car to practice with because it was a good handler on my no-mag wood track, free of faults and glitches.

                      I found the magnet cars a big challenge to drive fast, as none of them give you much warning when you are going too fast. The next thing you know, you are out, and often upside down.

                        Yeah, just put in a bigger and more magnet next time, farther towards the back, and the biggest honkin motor you can put in that beast.

                        Just an observation for future races, I was surprised on how poorly any of the Ortmann cars did on Area 51. I was disappointed on how slow my Capri qualified there with Ortmanns as I've always been around 9.5 to 9.7 with a good 23K car there with Super Tires. Any Ortmann cars seemed very loose and did not hook up at all.

                          Thanks guys. I'll do that for the CPR when that year of car is eligible.

                            Terry I drove your car, among others, and RL is right on. For all intents and purposes a non mag car among the magnuts. It was fun and a challenge but noe match for some of the others. I also found, as did RL, the lack of warning for these mag racers is disconcerting. Most handled lanes 2,3 and 4 ok but the tighter turns of 1 and 5 gave some cars (and drivers Moi??) trouble. It would take most of a 3 minute heat to find the limits and that resulted in fewer laps. The other thing I noticed which caused problems in the tight turns was the lack of coast. That is the fastest way through these turns and was for the most part missing. You just needed a ton of downforce and a very strong motor to make the fastest times..

                              Terry, there are no magnets in the CPR!

                                No wonder some of these cars were slow - they raced them backwards!





                                Great photos, nice racing. Thanks to everyone, especially the organizers and track hosts/drivers, for an entertaining year.
