Brian – I did the same exact thing. I have a collection of spur gears I have no use for.
Looks like this will be a race where the best motor has a big advantage.

All,
I must be missing something. I worked on my GT1 yesterday and discovered that any of the smaller spur gears will not work as the distance between the axle and the motor shaft is too big for a smaller spur gear to work. I tried a couple of different combinations and could not get anything to work other than the stock 33t spur gear.
Has anyone else figured out a way to use a different spur gear with the GT1 cars?

Marc,
Don’t discount the inventory of the club. Many members, myself included, have loads of spare parts for instances just like the one you described. Best to post what you are looking for and I bet you will find it. As they said in Harry Potter – “Help will always be given to those that ask”.
Lance,
That is a very cool track. It would be a challenge to marshal with all those tight turns on the inside of the track.
Marc,
All spec series are designed to make setting up the car as easy as possible and therefore calls for stock parts to be used. This makes it easier for someone new to the series to know exactly what parts are to be used so they can set up their car equally to the other racers. If all screws were allowed and someone found a screw that had a smooth section on it that had an advantage to the fully threaded screw then there might be an advantage. This is the case with just about any larger or national series I am aware of. People tend to interpret the rules their way to find as Mark Donahue put it “an unfair advantage”. I am not saying you are specifically looking for an advantage but I want everyone to understand the reason for the rules. It’s also much easier for a series manager to scrutineer the cars when they are all using the same parts.
Erik,
Holy cow! Racer Sideways does product a Group 5 Escort. I had no idea. Very interesting liveries.
OK – it’s time to make a decision on voltage. This will impact how everyone will set up their car.
I still say sticking with 12 volts is the way to go. Simply put, this will allow the stock gearing to work best for new racers and those that have more difficulty keeping their car in the slot while the rules will allow those with more experience to change the gearing on their car to match the level of their driving and car preparation.
Let’s have this sorted out sooner rather than later because it will also impact the Toyota GT1 race.
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.
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.
Erik – I am unaware of any Escort group 5 car that Sideways produced. They have the Capri and the Mustang but that is all I am aware of. Let me know if there is an Escort I am unaware of.
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.
