Final set of rules posted on the home page.
Build it strong.
Keep it simple.
Make it work.
(Leroy Grumman)This is all very academic at this point, but I would like to look into the possibility of re-bodying the chassis PROVIDED the new (printed) body A: contains all the detail elements of the Revo (driver, roll-cage, glazing, etc) B: The donor chassis is not cut or altered in any way. C: The replacement body weighs no less than the body it is replacing.
At this point I don’t know if it is feasible, but it would be cool to see some Pintos and Gremlins out on the track 🙂

-Warren ZevonPer 1969 SCCA rules, the B Sedan class has a engine capacity limit of 2000 cc. So the Pinto raced and the Gremlin was too big displacement, just like my Corvair. I attended the SCCA B Sedan races that included the A Sedan cars also. NO Gremlins until the later BFG series in IMSA. I have thought about using a RevoSlot chassis for a non-RS body. The C Production Porsche 911’s got added to Sedans by 1969 to satisfy Porsche since Alfa Romeo had jumped from the Production classes. I’m surprised RevoSlot has not added Porsche 911. John has a Porsche 911 that was the SCCA champion.
So maybe a pinto? Grind off the big bumpers?

"Enjoy every sandwich"
-Warren ZevonTwo problems have been identified on the RevoSlot cars.
1. The Alfa Romeo motor shaft sticks beyond the pinion far enough to rub the rear wheel and tire. Therefor we will allow the motor shaft to be ground or cut off at the pinion.
2. The Datsun 510 has a manufacture error on the motor bracket causing loose or misaligned motor. A cure for this has not been identified. More information will be included in the rules.
Another issue is the voltage for the race. Due to dusty track the 12 volt test seems to be causing wheel spin around the course. Another test will be run at the Dec. 21 meeting on the clean track.

I ran both Revo’s Saturday on a clean track at 12 volts and couldn’t break 4’s got better at 12.6 I would recommend 12.6
Agree here with David – running at 12 was almost sleep-inducing the car was so compliant, and that was with old, hard tires. 12.5 was a bit more interesting and I was able to de-slot if I wasn’t paying attention. 12.6 we didn’t do, but the bottom line is that 12 is what I’d set things at for a kid who is just starting-out.
Anyone have the tire number for “Stock Revo Slot Tires?” Need to put in an order since I’m pretty sure I ran old slot-it 30’s on that car for the rally. No clue where my stock tires ended up.

I’m in agreement with running at higher voltage. Do we have a weight limit? I can’t find it in the rules.
All,
I would keep the voltage at 12 volts. All we need to do is use different spurs and/or pinions as allowed by the rules.
Here is what the different gearing looks like running at 12 volts.
stock – 9t pinion with a 24t spur = 7,875 calculated wheel RPM
option 1 – 9t pinion with a 23t spur = 8,217 calculated wheel RPM
option 2 – 10t pinion with a 24t spur = 8,750 calculated wheel RPM
option 3 – 10t pinion with a 23t spur = 9,130 calculated wheel RPM
option 4 – 12t pinion with a 26t spur = 9,692 calculated wheel RPM
As a point of reference, I typically run all of my well handling cars with a calculated wheel RPM of 9,100 to 9,400.
See, no need to change the voltage to anything other than 12 volts. Everyone just needs to find the gearing that works best for their skill level. Run the gears that you can run to achieve the best results. More is not always better. Better is having a car that is drivable and stays in the slot.
Love that Paul Newman car. It can be seen in the movie Winning: The Racing Life of Paul Newman. Great movie.
This should be a competitive series.
Just as a heads up. All of the crowns and spur gears I mentioned earlier are currently available from Alan at 132slotcars and from Pendleslot.
