Using Oxigen RMS to create a (motor) B.o.P

As per version 8.3 the DiSCA GT3 tech rules allows race organizers to choose a spec motor for their events from the following 3 options.
1 Scaleauto SC-0027B Sprinter Junior rated at 18.000rpm
2 NSR 3024 Baby King rated at 17.000rpm
3 Sideways Baby Raptor rated at 17.000rpm

A new "local " Belgium/Dutch DiSCA GT3 spin off would like to use both the NSR Baby King and the Sideways Baby Raptor simultaneously in their series, assuming that since both motors were equal as both are advertised as 17K motors.
But preliminary testing indicated that some motors were more equal than others.

This topic will report on the tests and quest to see if the Oxigen RMS can be used as a tool to create a B.o.P (Balance of Performance) between different Motors.

Some post on this topic have been made in recent days. I will (re)post them here as Quotes.

With kind regards
Tamar

do not be put off by our comments. I think we are all trying to help here.
My main concern (as I told you in person on our chat) is that Chrono max power setting might be too crude as a BoP solution.
To me it feels like implementing BoP in 1:1 scale by putting a brick behind the throttle pedal so that the driver cannot press it fully and the car will not get full power.
In RCS64, I can build profiles to limit the full power but in RCS64 I can use all the 64 positions/values of throttle information to achieve this not just the first X%.

Hello Gio
In 25 years of slotracing and race organization...I've developed a thick skin....so don't worry. a few posts won't put me off my track.
But I must admit I'm a bit put off by comments on how people feel, think, imagine... how bad such an idea would be...
...while at least some of them could have started up their Chrono, do a run with car at max speed 100%, do a second run at 80% and post their findings. At least then their opinions would be backed up by first hand experience.

Now that would help not only me...but also this discussion.

Ok time to check out (the Hotel) and head for Le Mans.

With kind regards

ok, done
Oxigen environment RMS
100% VS 80%
yes, the cars are slower, but not 20%
in the table under the heading percentage you can read which number this should be if the speed is reduced by 20%, in practice it comes down to 10%

I think that we need more than this. In particular, you want to have two identical chassis one with the baby king and one with the baby raptor and then use the RMS to balance their RPMs or speed at wheel. Then you want to do a test run with both chassis (with a body of course), say 100 laps each, and see what are the differences, if any.

I wonder if I will ever see the day when Power ([watt]) value is used in place of RPM, when discussing slot car rules set...
I know I won't. Therefore, in the light of the future electrification, when I will buy my next car, I will shop around for the one with the most RPM available. Makes sense... :confused:

this is the reason I try to get attention for a maximum speed value. Whatever engine you use, which gear or pinion, tire size, etc.. we all drive just as fast. Then and only then will the best pilot come out!
By the way, this usually doesn't change the top 5...these are the pilots who can get everything out of their car anyway.
Added to that...The H&B testbench...will sell like cookies lol

Dear Slotfriends
Just returned from my 14th? visit to the Le Mans 24hrs race, one by the way in which the performance of every car in every class (with a total of 62 cars) was governed by some sort of B.o.P. Some of which worked....some producing more equal cars than others ;)

As I mentioned earlier, won't post here until I've collected sufficient data on the motors under investigation and with a list of tools and testing procedures to substantiate the presented data and my conclusions.

So in the mean while I have a question for you all. How would "sufficient" data translate for you guys ..in numbers?
Test 10 motors each, 20?,30? 50?...100?

with kind regards
Tamar

As a start I would like to know the distribution of motors (# of drivers using the Sydeway motor vs the # of drivers using the NSR motor) in their analog series.
