Jim just reminded me that June 11th is our Endurance Race.
I’m fine with going to San Antonio one day before but I probably won’t be going to Kings that Thursday.
How do you guys fell about that?
All right fellas,
Finally saw some light setting up a team race. We will not be using PC Lap Counter, we will use the good old Trackmate. The only way to make this work is to add the teams as drivers (combine all 3 drivers in 1) instead off adding the individual drivers to the rotation.
Please let me know the name of your team, it will be easier that way. Get your creative juices going and come up with something nice.
Team 1, represented by color gray: Ary, Pricilla, Marty.Team 2, represented by color red: Jim, Clark, Russell.Team 3, represented by color purple: Shawn, Roy, Brian.Here is the rotation sequence:
This table will be available the day of the race. You won’t see your name on the timing system, your team name will be displayed.I understand that some of the motors perform a lot better than others at 10 Volts. The last motor I drew was running at 17.6K after break-in, I was still able to get it going with a 23X9 gearing (2.55 ratio). Some may say that I could have tried a different gear ratio (ie 25X10, 2.5 ratio), but not really.
I think that by now, all of you heard of me saying never to use a 10 tooth pinion; the reason is simple: All slot.it gears are 48 pitch but the pinions are not. The 8 tooth pinion is 46.18 pitch; the 9 tooth pinion is 50.80 pitch; the 10 tooth pinion is 55.42 pitch; the 11 tooth pinion is 60.04 pitch. The difference in pitch is due to the fact that slot.it needed to fit all sizes of pinions inside the channel that stops the gear from moving away from them — this is a HUGE design flaw.
Back to subject; to get the better gear mesh you need to disconsider 10 and 11 tooth pinions, making the gear selection very limited.
With the current track voltage set at 10 and motors as slow as 17K, using the smallest “usable” gear ratio (9×23), the maximum RPM at the wheel is 6.6K (17000 RPM / 2.55 ) — The sweet spot for out track is around 7K for an inline configuration without ballast.
Now, if we increased the voltage of the track to say 10.5 or 11 volts, whoever picks a slower motor has greater chances. The problem here is that the person with the fastest motor could still extract better times using ballasts, so those would become illegal. Without ballast the car is still limited to the lower 7K range at the wheel or it becomes unraceable (I make up words as I go).
—- Basically my suggestion is:
- 8 or 9 tooth pinions allowed
- No ballasts
- Track voltage at 10.5 or 11 volts
Let me know if this makes sense. We can always give it a test run on a Thursday night.
Ary.
I contacted Magnatech a few days ago. Basically the large track is occupied every Sundat starting at 3pm, they only open at 11 on Sundays. On Saturdays, their races start at 7pm which means that there will be people practicing during the afternoon.
In order to get that track we really need to check the club members desire to do this.
We could try to run 4 at a time, we would probably have to generate our own round robin table and keep the scores by “hand” — I have used their software before and I’m pretty sure it does not have a round robin option. With 8 guys; four racing at a time 5 min heats with 2 min between each heat, the entire race will take 2:00 hours; if go for 10 min heats that climbs to 3:20 hours.
We would probably have to rent the entire track for 3 hours on a Sunday.
BTW, we probably need 3 marshals at all times.
If I can still fit inside a go-kart …..
We need to have a large participation in order for this race to work — we need marshals as well.
Quote:There were rumors in the pits that Ary had increased the bore in his motor and thinned out the body of his car using the old acid bath trick. Either way it was very fast.
LOL. There is definitely something “wrong” with that motor, but I never heard of “increasing bore??”. I will get the Scalextric mustang back and running for the next race. If anything I think that motor is a 21K labeled as an 18K — and no, I have not done that myself.

It depends on how many guys will be racing. I also don’t know if you want to use the Last Slot.it challenge as a guide or El Piloto but raving six racers I would suggest first place with sixth place, second with fifth and third with fourth. With seven racers the suggestion is first with sixth and seventh places (2 heats per racer), second with fifth and third with fourth.

One car per team using our BRM rules and RED motors (I will bring some bacon to fry on top of them).
tele52 wrote:Ary,
Does the “team format” mean one car shared by 2 drivers? Would each team run 6 total heats (each driver races in all 3 lanes)?
Jim J.
Exactly.
We talked about running an endurance race with 10 min heats; teams of 2 based on either El Piloto or Slot.it classification.
Now, the issue with the red motors getting super hot and losing performance is actually a nice challenge; a team would have to balance speed vs. longevity. If you use a taller gear ratio, the motor wont get so hot but you also loose speed.
I would suggest to race 10 min. heats every 3 minutes; if your motor burns out, you can change it on green.LET’S DO THIS !!!!
I will bring some computer fans to cool down the cars between heats.
