Just going to build a couple more Sideways Lamborghini Huracan GT3.

Now they have been out for a couple of years what tips and suggestions has everyone got ? Weight setup ? Ive played with a SW setup which went well, but was now going to play with a couple of AW setups for our big wooden club track.

Anyone tried the different pods ? standard vs hard grp 5 vs slot.it pod ? how about the long can and also the slot.it flat 6 motors ? We race on magna braid so I was going to try NSR evo 21k, blue sloting plus and slot.it red flat 6 motors

thanks

It's a great model. There's a lot on here about building one and how fiddly it is. Mine is the Carbon Ltd Ed model.

Since these photos were taken I have done more work to mine.

For me it's too nice to really race in anger and as I have a brace of Mosler's in various configurations, the lambo & a lot of other GT cars are "back ups" that get a warm-up run out but not a race.

See photos of lead placed around front, that 21k motor is more than enough, our club track has a 9.3m straight. I think I've probably got an NSR Evo King 3 21.4k rpm, 350 g-cm & re-geared. Also note spring suspension using side mount points and rear one with no screws, really does allow controlled body roll and the NSR extended screw-in guide.

I'll try to add recent photos as I know I've changed the wheels to slot it LMP design and I think I'm using a Slot IT AW 1.0mm offset - racing on rails and using high torque/mag effect motors if you can lower rear ride height to 0.5mm or thereabouts any decent set up car (that's with all the other work done, body float, smooth mesh etc.), will corner with greater speed.

R3,
Nice pics.
I have a Huracan that i bought for my son to race on ninco track.
Didn't take long before it needed some upgrades.

A main upgrade requirement was the flexible wing and struts.
The factory fit wing is most fragile I've ever used on a track.

Next was a motor upgrade because the baby raptor just does not cut it against the competition.
An eBay purchase, avant hurracan was just the job.

Seems like my son will never build an interest in model making or racing.
If I'm going to race this car in angerit has to be a GT car to LSC rules so an inline long can conversion so an offset slot.it pod with a high power motor will be the way to go.

Could probably use a paint job too. That factory fluorescent green isn't very pretty.

Alan - the pictures are of my car, me.... Max.

Steve built Tony's Lambo (Wood Green North London Mob), in-line and goes very well in GT but not against them Moslers. He used a scale auto long-can they all favour, with 1mm off set slot it mount.

I have kept a rubber rear wing for when it's needed...

There are few versions of this model out there with different specs. The the full monty raptor motor is practically the NSR Evo King 3 long can [is 21.4k rom & 350 g-cm]. The baby raptor is the 17k rpm. If you're racing on a club wooden track then you may be better off with the higher spec motor.

Also some kits come with adjust blocks for the sideways motor mount. See photo, they change the offset for rear ride height. I think that's quite a neat solution, rather buying new mounts to get the same effect. My Group 5 BMW 320 model came with same mount and different offset blocks [0mm, 0.5mm & 1.0mm offset].

I only have one fitted it with a B.R.M 23 K in sidewinder form with rear axle ballraces, yellowdogs on the rear bit of weight up front and in the middle, titanium rear axle, slot it gears 11 x 34 and it,s rather nippy.

The Lambo is a nice GT3 car. I prepared one for the DiSCA Suzuka event (we raced twice) and it was one of the fastest cars on the track (not in my hands of course

.

For Ninco, I suggest to make sure that the front axle is barely touching the track and that most of the front is sitting on the guide.

Funnily enough, I have recently changed the configuration of this car to race on my scalex track and I am not able to make it stay in the slot.

I race on Scalextric Sport track, standard at home and with painted smooth surface for thee clue track, i haven't had any issues on either surface.

As far as I'm aware the other club members cars are fine, they run them in-line and we're all using Long-Can motors, NSR/Scale Auto, every car has some lead at the front.

One thing I did change is the guide. Mine is the extended, screw in NSR item. It's possible the other guys have either changed or filed down their guides.

We all set up car with front wheels just barely touching the track. Not sure if any of that is helpful?

Nice lambo. Are they Ninco wheels ?

I am going to try 2 different pods. Ive got a red hard sideways pod and an AW slot.it 1mm. From what ive been told the slot.it pods seem to work better

I'm working away from home at the moment but when I get back I'll post a recent photo of the ever evolving spec on the Huracan.

Yes those very nice wheels are Ninco 17" from the Lightened Pro Race range - hard to find now.

Luckily I had quite a few, bought as part of Ninco bundle clearance from wholesaler.

From memory I think I'm using a 1mm off set slot it AW mount with NSR Evo King3 21k motor.

I generally use Slot It mounts in my Sideways cars, including my on-the-pace Ford Capri's that race in anger at the club track. At the risk of straying from the Lambo - here's a couple of photos...

Wheel Tire Car Vehicle Land vehicle

The chassis with said mount... that's tungsten weight not magnet, suspension kit, it's probably been re-geared too. I reckon this spec has evolved since these photos were taken. I have 2 of these in same livery and use "best car" for races and the other to develop further and improve. As second car gets better the other becomes development, and so it goes on...

It does... Very few, but after 50+ laps, those decimals add for a whole lap or two. 😉

Photo of my Huracan GT3 - in current spec. no surprise I did go with 1mm off-set Slot It mount, orange label Flat-6S, NSR longer guide ....

Slot It - slightly smaller 16" different wheels to the Ninco 17" - they are on my Mercedes Vision Concept Car by Area 71, as featured in a Batman movie.

do you use suspensions on the side mounts of the pod?

Grunz

Yes, in most cases nothing in the rear points.

I've done so a few cars including a Slot It Group C Porsche with a long-can motor in AW (not for Group C cat racing), MSC Subaru was one the first. I found better controlled body rock, likewise on the Huracan. It keeps the back end free for maximum movement. Doesn't suit all cars.

My NSR F1 car has complete overkill but does work for me [or gives me greater confidence] - spring suspension kit front and mid points and the smaller magnet suspension [Slot It] on the rear mount points!

My theory in looking for controlled body rock, springs and dampers?

Thanks Max. I know that this setup works well on thunderslot cars on wood.

I will try this on my lambo as well for scalex and carrera tracks

I was about to post pics of mine, but then I read "magnabraid"

So you need all the motor magnet you can get. Just find a cobalt magnet FK180 motor about 21k with buckets of torque, and use a Slot.it hard AW pod 1mm offset with ball races Code is CH119, ball races CH105.
Use 16.5mm air rims and 19.5 x 12mm Ultragrips glued and trued with a rubberised glue, so the motor can't spin them off the rims.

You should end up with only about 0.75mm track clearance, and 1mm going down the straights.
And the hard red pod, and a big guide are probably useful additions.

But if you plan to run on any wood tracks without motor magnets; a 1mm offset Sidewinder pod, and a gutsy FC-130 is better stability out of corners than a twisting boxer motor setup.

I am running mine with a hard chassis, a Slot.it CH115 sidewinder pod & CH105 ball races, a ScaleAuto SC-0009b 25k motor with 225g/cm torque. Tyres as above on the stock rims.
It is running similar lap times to a fully worked Slot.it Porsche EVO GT1 which has a Flat-6RS power plant.

Our club track has magnabraid but we have a 25g magnetic effect rule so high mag motors needs steel shim on the bottom to reduce the effect.

After that, all the top Racer/Sideways cars in our club have SW pods if one will fit without body interference.

Have you got an inside shot of the weight ? I needed quite a bit of weight to control my SW shark 25

Nice one thanks for sharing. shark 25 is as big as we can go in my local club. How does that compare to the scaleauto 25k SC motor. Seems the scaleauto motor has about 20% more torque ? That would be quite a handful on small and medium tracks ?

Yep R377. The SA motor is much higher torque than a Shark 25, and is equal to about a Shark 30k in power, so I have it geared a little higher than typical, to provide the desired amount of acceleration and braking.

- I am a "late braker" - I like lots of stopping power, and often overtake a close competitor under brakes into the Apex of a corner.

From memory I am running a Slot.it 12 tooth ergal pinion and 32 tooth spur.

By coincidence, I just did some final tuning on this car today, ready to compete in our open GT1 class tomorrow at club.
And as I took these pics, I realised that all that is left of the original car, is the wheels....
I changed chassis, replaced a damaged body, replaced the pod, motors, gears, guide. Fitted new body screws with soft spacers, the Slot.it 0.5mm offset pod has been lifted a further 0.5mm with the addition of soft spacers between the underside of the pod legs, and the top of the chassis. The front tyres have been coated and polished to remove the grip, the rears replaced with Ultragrip 19.5 x 20mm

I have about 10 grams lead scattered various places on the chassis for best balance. I haven't lighted the interior or glass.

That would be worth a fraction more speed.

When I get time, the visible parts of the chassis need a matt black makeover.

It has plenty of legs, brakes very well, but most importantly, that very stable trundling feel that the Huracan's have, has been retained, just at around 10% lower lap times than a well tuned standard one.
