(Leroy Grumman)Last year I had a lot of trouble getting my magnetic downforce within spec. Does anyone know if rotating the motor 180 degrees might make a difference?
"Enjoy every sandwich"
-Warren ZevonI tried that, but it did not make a difference. I think we need to look at this series like we did the Thunderslot series – as long as there are no visible signs of someone trying to increase the downforce of the motor, the car should be allowed to run as is unless the downforce is drastically outside of the mean. For my car to be at 132grams of downforce and not be allowed to run even though it was completely stock is absolutely ridiculous. True, you can reduce the diameter of the rear tires to increase the downforce but we can police that by looking at the ground clearance of the car.
Agree. Let’s fix the minimum ride height and go from there. This needs to be simple.

(Leroy Grumman)After a robust discussion and more than a few test measurements of last year’s cars during the club’s meeting on Saturday, September 13 the decision was taken to take the first race-day downforce inspection results and, based on the variability, determine any future adjustments to the rules.
It is worth noting that the chassis rubbing on the track is still prohibited, so racers are encouraged to keep that in mind with their builds.
Also worth noting is that a second decision was taken to reintroduce the ‘B’ class with this race. The ‘B’ class will be run at 10 volts. Roster to follow.

Keep it simple.
