I sure would like a chance to run the 2018 rally class on the rally track so that we can sort out car issues like we have been doing with the first three new classes this year. Please set aside a Saturday after the regular race and a Thursday or two for test and tune.
We have learned a lot from early testing with five or six cars for the Thunder Slots and are making some real single car tests for the MRSlotcar setup that were not expected to need changing.
So far on Thursday evenings David and I have my roadster and his coupe. As best I can tell David is a better driver than me, but the racing is close with 4.0′ s and some sub 4’s. We have practiced in real drastically different track conditions. I have broken the 4.0 second barrier, but not as often as David. David has not expressed faults on my car recently so it must be getting close. I am not having guide problems with the stock guide. We have changed our front wheels to aluminum and I think Zero grips, but I think the Goodyear fronts may be ok. I only have the tiniest ballast (little finger nail size) near the guide.
I bought POWER SHOT Electric Motor Cleaner Spray at Hobby Town Sunday and cleaned the RevoSlot Porsche today. The axles, bearings, and spacers all had black deposits, most of which had gotten hot and compessed, but cleaned off OK. The parts run much freer including the front end.
I trued the front stock tires on the stock plastic wheels like Marty suggested. Slow and light touch. They are round now but they have differing amounts of tread in patches around the tire. If I followed the regular club practice of truing tires until all of the tread is gone, I might have problems, but so far so good. The read slicks that came in the box are OK, but they lost a little chunk where the grub screw driver passes against the sidewall of the tire.
I’ll have the car long Saturday if you want to check it out.
I trued the front tires of the ThunderSlot carefully and discovered three things. The front axle is NOT knurled, so the plastic wheels side off without damage. The plastic wheels have inserts so I could put the tire truer axle through the wheels. I trued very carefully, test driving twice, still hopping after first true. Then discovered that the fronts were true but soft, very unlike our usual hard zero grips. I did not run laps after the last true, but expect real good times. This is also the car that lost a front axle height adjustment grub and I am still waiting for those parts.
I have changed the number on my blue and silver Revo Slot to 68 with red numbers. Now it also has blue wheels in front and silver in rear to match the body colors.
I do not like the idea of truing the front tires on stock plastic wheels and force fit axles. My roadster seems to bounce on the un-trued fronts. Marty tells me a very light touch on the truer will preserve the stock tire and wheel, but will it preserve the force fit on the axle?
I have had the #30 Gurney roadster for almost 4 months. I would change the number to 48 if I must to satisfy the “dibs” idea, but only reluctantly. It may be too late to really call dibs. (Letting Slot.it McLarens in the series would make more cars available;)
11 volts seems plenty on this light car.
Happy New Year 2018 Series!

CAUTION ThunderSlot rear wheel on one side of my roadster had the correct coarse thread grub screw and the other wheel had the fine thread front suspension adjustment grub screw. After I trued the tires the wheel grub screws both came out. I did not get the fine screw back in its original wheel and stripped the wheel threads. Then I stripped the other hole in that wheel. Nice. I have looked at both screws and the screws on the wheels I just received in the mail and I never would have guessed they would use 2 different grub screws. The Professor lists two different spare grub screws, but I have not figured out which is the wheel and which is the suspension.
I’d like to bring bbq brisket from Rudy’s. I can pick it up on the way from work at the golf course. Roughly how many people do we expect? If not brisket, what else should it be to make a meal?
Not sour grapes about the 2018 classes, but I think we should reconsider the ThunderSlot class and add the slot.it McLaren. We could get together a couple of the McLarens already in the members hands and a couple of Thunderslots in a pre-season race with comparable skilled drivers and see if they are competitive with each other. The cars would need to be similarly prepared and geared with very limited changes of course.
