Having finally received my long awaited Nissan(s) and posted on their appearance in stock form ...
..they may stay like that until we return from Rockingham's Tres Petit Le Mans...but def not much longer...
... as the #23 car will be raced by my team @ Suzuka in the DiSCA GT3 race of Jan 29th 2022.
So this topic will be on how we'll prep the car(s) to DISCA GT3 spec, meaning chipping it adding lights (that will be fun)
And the fabrication of some flexible lightweight components (vacformed interior & windows, laser cut rubber rear wing mounts)
Team might even have even a certain Italian guest driver. ( and no this time that's not Grunz)

Tire Land vehicle Car Vehicle Wheel


Hard Nut to crack.
This specific Italian gentleman has given me a very hard nut to crack, cause when I check the reference pictures of this exact car...
...and compare it to the Slot.it car, I can only find some extremely small areas where I can possibly improve the stock car.
More than happy to extend the black on the side skirts, as reported masking on stock car not really a match to the fine finish of the rest of the car

And there are the solid rearwing supports, these can be lasercut from rubber with some of the openings of the 1/1 wing.
Can also extend the slots for the supports further down the trunk, will give the rubber supports even more room to "Flex"
But look at the detail, Tail lights surrounds painted in correct color...even that embossed Nissan logo is represented on the Slot.it car

So..make note, add red tow band and some mesh in the lower grille. Rear window seems to have a split frame underneath (decal?)
The only thing that looks a bit "off", is the back end of the roll cage...but haven't been able to score good ref pictures of it.

Chassis
DiSCA GT3 rules have a more (box) standard approach , so no trick pod mounted diffuser on this car.
Stock screws already replaced with SV Workz Titanium M2.2. Side suspension will be fitted.
Not clear yet if 1,0mm Offset Evo pod will give 1,8mm Ground clearance under motor with 20,8mm ø Scaleauto Procomp wheels.
Regs require running Scaleauto Baby Sprinter motor, hope that won't piss off "Italian guest driver" too much.
But then again Pace car he will also drive will be fitted fully with stock parts...including stock traction magnets :oops:
Yep you read it right, Traction magnets, nobody is going to bump the Official Pace car off the track on the formation lap(s), as previously happend at Le Mans 😇

Oxigen
O201C chip obvious choice here, testing will determine if it should be mounted longitudinal or transverse (weight distribution)
Good thing about running that big GT-R is...plenty of real estate on chassis for either configuration.

Body works
Side skirts will be cut of chassis and glued to body, most likely will do the same for the front splitter to allow independent set-up of body and chassis.
4 small Body supports will be mounted in body right in front of rear wheels and behind front wheels.
4 grub screws will be added in chassis underneath to adjust ride height. Been there done that...doing it next month
Dive plates are integrally moulded with the body, pretty sturdy too...will have to see how those will withstand the challenges of Digital racing.

Stock body now at 23,7 total. Vac formed but detailed interior should save 3,5- 4,5 grams off. Not too much gain expected from vacformed windows...
...as plastic windows are already at minimum. So estimate maybe 5 -6 gr max from total vacformed parts.
Which mean there will stil be a lot of (careful) dremeling & scraping to get the whole body down to 14-15 gr...so there's room enough for.....
Automotive lighting Product Black Motor vehicle Font


Light(s)..let there be
Estimate 3,5 gr needed for SP44 light kit to power plenty of LED's, Slot it has moulded front lights as separate parts, so these can be done off the car.
The only Jazz I might be able to add will be some pretty purple led light peeking through the front grille.
That is unless DrC and Flag Slot manage to get their "functional LED Number/ Position Display" functional in the next month.
Oh.... good finally see somewhere I can cut into the body, opening up the bumper for the bottom purple leds :)

Ok that's it for now, got my to do list for the Nissan(s) but next update will have to wait till next month... but definitely

To be continued

With kind regards

Because one of the things DiSCA rule sets set out to do, especially with GT3, is to facilitate as much variety as possible on the grid. Would you like to race a 62mm Porsche against a 66mm McLaren?

And the fact is that we’ve achieved that. If you look at our GT3 grids over the years the range of different cars has always been apparent. Scalextric body cars have both won races and achieved podiums and I think thats a direct result of us balancing the width around narrower cars.

Anybody that’s been racing slot cars for a long time knows that whether it’s a club race or national competition there’s always that one car that’s favourite for any given rule set. A look at the UK Analogue GT3 Nationals for example sees several years of “every car is a Corvette C7R” and has now become “every car is a Scaleauto Viper”. That sucks in my opinion. I’m not singling out this series btw, it happens everywhere.

Except DiSCA…

While it’s not quite true that every car in a twelve (plus..) car grid is unique, it’s happened on several occasions, and if there are duplicates in a field then there’s usually only two of any given car. That’s a huge win for the ruleset and one of things I’m most proud of having achieved with DiSCA as a whole.

While it’s true we could BOP every single car individually the amount of work to do that and amount of cost we would incur to test everything would be astronomical. While I wish that administering DiSCA was my full time job, it isn’t. I don’t even have regular access to a track, and Tamar, Gio and others are extremely valuable to our organisation because they do, and can test here and there.

DiSCA has a donate button on it’s website which has only been used once since 2015. And while I’m not lobbying for donations I would like to use it as an example that people don’t care what it takes to create solid rule sets and organise competitions of a high standard. They just expect it to happen. And again I’m not complaining, I’ve done this long enough to know this is just how it is. But if anyone has expectations for individual car BOP then you better get clicking that button so we can buy every car on the market, chip it, and spend 8 hours a day testing 😉

Great post mate. 👍🏼

I think the only way to get the hobby alive and get a chance for it to grow, is to include people with love for the hobby and that extra money that they can spend without too much problem, I know maybe it’s not me or you this last guy, but believe me, they are out there. Personally I have meet and make friends with some guys who (for the love of the hobby) have sponsored one day slot fests(and many more things), paying all costs and entry fees, inviting all guys to this kinda of events and guess what? Even with free access and free food and free track, people don’t go because many times they got complexes that won’t let them enjoy the hobby(human specie are way to complicated 😅).

There’s no secret formula to involve those guys with enough money to invest/sponsor the hobby, but I’m pretty sure they will follow an honest effort for the hobby and those who inspire and transfer the racing spirit form the 1:1 tracks to the 1:32 world of slots.

It wouldn’t be a bad idea to ask the Masterslot guys in Spain on how they finance their events, but as far as I know, it’s an event with 40 teams or so(3 members per team), with a waiting list of more than 20 teams, so they must be doing something good for an analog event😉

Like Bon Jovi would say, “keep the faith”

Cheers

I would add to my last post , take for example F1, Stroll (Sr) is a character that many don’t like but without him there wouldn’t be no AMRT, we need those teams for F1 to exist, same goes to slot cars and fortunately, there are people far more nice than Mr Stroll 😉

GDSLOT (Sorry I don't know your name) as exacltly translated my feeling about the Disca association and its members:
a 1:1 tracks to the 1:32 world of slots
Click to expand...
We feel the passion for this hobby, we feel the connection with the full scale racing cars, frankly I admire the team for its dedication, "Chapeau bas Messieurs".
I only had the opportunity to talk to Tamar, but talking to him is like talking to Maurizio Ferrari, how can you be more passionated than them?

As a new comer to this hobby, I see the Disca limited to UK. I don't see it right because they are many passionated peoples like you everywhere.
Maybe more communication are needed? More on FB? Videos on YT? Maybe demo should be organised outside UK? Why not organising a race series event in Europe, to start with?

Anyway, not sure guys where you want to go, but as said by GDSLOT, I'm sure many will support and follow you...if you ask.
Anyway, you have a beliver here.

DiSCA has raced in Europe almost as many times as in the UK, I would say.

Tamar’s own club SRC Eindhoven has their annual double header digital event in January for GT3 and WEC cars. Other clubs in Netherlands have also raced under DiSCA rules and of course the exciting Paul Ricard project in Belgium is just around the corner..

In 2019 we has a European championship composing of a UK round, Netherlands and Spain at the Cric Crac Superdome near Barcelona. We’ve raced in Vicenza, Italy on the Mega Monza circuit with Maurizio. I’m pretty sure that there are Danish clubs racing with DiSCA standards, too.

Covid killed the momentum, to be frank, and things are only just starting to get moving again.

As regard to social media, we did a fair bit but found it gets in the way too much. It needs a dedicated person for that, and I already wear more than enough hats.

Coming back on the topic.
I've received some Sponge tyres, SC-2020 as set by the Disca rules.
I've tested first on my Slot.it GT-R GT3...and men! What an improvement!
So I've tested the tyres on two other cars.
On the left, the Slot.it Nissan GT-R GT3, then the Sideways Huracan, and then the NSR McLaren.

As discussed on other topics, I also have tested difference between loose and tight motor mount.

My wood track is 15m long, with the Nissan, I've improved the lap time by half a second from 5.39s to 4.88s. Best lap with loose motor Mount.
And more importantly, there is a hudge improvement in the car handling.
I'm so happy that a tyres swap can make this car a very good performer. I still think I need to had some weight to reduce the de-slot and improve the lap time.

With the Huracan, there is an improvement by 0.250s, at 4.661s for its best lap. Best lap with loose motor Mount.

With the McLaren, the time is improve by 0.42s, with a record lap of 4.520s! Best lap with tight motor Mount.

All cars see their lap times improved by quite lot, considering the track length.
Also, all cars run smoother and quieter with sponge tyres than with rubber tyres.
In handling, the best improvement is with the Nissan GT-R GT3, the car finally became competitive.

Regarding the loose/tight motor mount. With my short experience, the results seems depend on the car and its mount type.
With the Nissan, with the Sideways tyres, tight mount is better by 01.s, but equal with the sponge tyres.
With the Huracan, same performance with Sideways tyres, same lap time with tight and loose, but loose mount performance is better than tight with the sponge tyres, by 0.16s.
With the McLaren with both tyres types, the tight mount shows an improvement with their lap time. By 0.05s with the Sideways tyres and 0.14s with the Scaleauto tyres.
I've runned 5 times 10 laps, and it seems that the improvements, in all cases, are consistant.
So, I need to see how it works with other cars.

Overall, the Scaleauto procomp 4 tyres are a really nice surprise. I have to try the 11mm width version and maybe other compound.
I've very happy with this discover and plan to expand the test with others cars. Likely that this tryes are going to become my to-go tyres.

Ah, I've took a close shoot of the Scaleauto and the Sideways tyres:

The surface degradation is very obvious with the Sideways tire (right) than with the Scaleauto (left).
The good is that despite being narrower, the Scaleauto tyre perform the best, by far, on my track.
Happy man here!

Interesting findings, mmm, wonder how would they perform on a Ninco or Policar Track due to high degradation surface, if you happen to run a test with those tracks please report back , just as an academic experiment😉

Have you used any additive for the sponge tyres?
Chris' suggestion of using Nivea cream really works - plus your hands are soft and smell nice after using it! ;-)

No additive for the tyres, they were out of the box.
After publishing the articles, I’ve tested others cars, all have their handling and lap time improved.
With rubber tyres, on corner, some cars, especially the light ones or the ones with high CG, doesn’t turn smoothly, but are rattling. But with sponge tyres, they all turn smoothly. The cars behaviors are much improved and much pleasant to drive.

the only downside I need to see on the long term is the evolution of the track. The sponge tyres let a mark on the track, that were no so obvious before the test :

It seems when wearing, the sponge tyres residue are sticking to the track, while with rubber tyres, it’s like real tyres, small parts laying on the track.

Well, put it in this way Claude, some people spend time and money to get that effect on their track....you get it from free by running those tyres ;-)

Tamar, am I allowed to hijack this topic a bit and continue with my build/setup of the Slotit Nissan GT-R GT3?
Allthough it's not a full spec DiSCA GT3 euroseries, but pretty close and quite similar.

Sure Tom be my guest, only make sure to add or mention which and who's car it is in your post...as we're both using the same #23 Nissan body.
Sort of to avoid the "Confused? ...you won't be after watching the next episode of...."😅
