What are your feelings on R1/Tight bends?

8835 Views 71 Replies 27 Participants Last post by  Si.
Just curious as to what those with experience of putting together different track layouts have experienced with R1 bends/hairpins/chicanes?

As a severe Motorsport enthusiast I am mocking up layouts and very quick to throw one r1 combination bend somewhere in each layout I come up with if nothing elsefor variety and a different type of challenge.

I am worried with slot cars it may not be so much of a good idea?

Do they ruin the fluid tempo of a track with deslots or do you like having them there?

I am leaning towards trying them out but its an expensive gamble to blow money on them if thy are gonna cause hassle?

any thoughts welcome

Hi jasperok

My MRW Motor Speedway circuit, runs like a dream !

Loads of R1's as well as 2's & 4's in there.

My previous tracks the same.

You simply CAN'T make a challenging real-world chicane or Monaco style hairpin without them.

You don't deslot on R1's, if your brains in gear, and you haven't got a rubber-band round the throttle.



I gave up 'ovals' & 'figure of 8's' when I was 10 and discovered there was something else apart from R2's...
...imaginatively called R1's, buy LOADS you'll have a great time !

If your throttle finger doesn't work, stick to an R4 oval or figure of 8 !!!

"Seconds OUT......ROUND 2 !...."

On my left for the R1's...we have...

On my right for the R2 Box-Set...we have...


I wanna fair fight, & NOTHING below the belt please...

Hi jasperok.

I'm afraid sadly 'I' ...DON'T...know everything.

I do have a sense of humour though ( some say, anyhow ! )


Hi jasperok

If people turn up at your challenging track and don't like it, I shouldn't worry about it.

The people left will be the ones you want to race with.

They can get the grumps, or get to grips with a rewarding technical circuit.



Can anyone tell me how many R1's I would need for Long Beach, California, USA.

They been racing there for donkeys years, so I guess the drivers don't moan too much, & just DRIVE the circuit !

( by the way, the normal technique at Long Beach, is NOT to drive 2 or 3 abreast, around the hairpin & 90's )

The stuff that LEGENDS are made of.

The La Source hairpin at the fearsome Spa-Francorchamps circuit in Belgium.

More classic 90 degree street-circuit action, with Senna at Phoenix, USA.

( always check the binoculars are round the right way at street circuits, it's CLOSE, REAL close ! )

I think a few R1's for a decent 1:32 to capture the edgy spirit of the very tight Phoenix GP circuit.

Hi jasperok

Fluid-Tempo means 2 things to me...

...Ayrton Senna taking the chequered-flag for another stella street-circuit victory at 3 PM.


...Tony Humphries taking a swig of his 10th can of Coca-Cola at The Ministry at 3 AM.

Lifes too short for regrets dude.

Just do what you feels good.

I'm outta here bro.................

Oh jasperok

I have to agree with a few members.

If your modelling 'The Indianapolis 500' in 1:32 nd scale...

DON'T USE R1's !!!... it ?

Hi Snurfen.

I see your not the Wing-Commander anymore !

What are those pair of dudes ?...Ferrari water-skiers ?

Druids at Brands is a great corner, seen a few F1's buzzin' that baby back in the day !

Don't support the R1 thing too much old-chap.

I'm lookin' to score a dozen more on Ebay, so I'm hoping the thread encourages members to bin 'em on 'the Bay' for coppers.

Think I might score a load cheap now !!!

"Gee this threads EXCITEING !"

"I bet you guys are all real Lee Marvin fans !"

Me too.


P.M. me anyone who wants to get rid of their R1's cheap.
Hi Mr. Olufsen

Nice to have at least a fan club of 1...!

Am quite tempted to flash some cash on one of those NSR 917's, for a bit of R1 non-mag action myself.
I take it you have a lot of fun in 'mini Sicily' with yours.

Have you got a couple of snaps or a drawing of your new multi hairpin hill-climb.
Love to see 'em.

I am thinking to do a fairly complex single-lane hill climb here this spring.
I have been drawing it out in UR3, by useing mostly R1 sections in UR3, and then erasing the extra lane in photoshop.
Since all my cars go fine round R1 inners & outers, it's a good way to ensure the layout of the proposed hillclimb will work good.

Driving 'well set up' cars like I'm guessing you do, around tight corners IS A BLAST !

The funny thing is, people talk about 'de-slots' on R1's; but with 'low centre of gravity' cars here at MRW, all the de-slots occur here on the FAST corners; where your tempted to 'push it', rather than having the patience to SLOW DOWN on tight corners, where you just know that your gonna loose time if you push too much.

Hi Christian

Yeah...Temporary nature is basicaly 'semi-permanent'; which in my book is 'virtualy SOLID' ( which is VERY permanent ).
I would make a VERY poor diplomat I think; but when have racing-drivers ever been known for their diplomatic skills !!!

My way of thinking is:- I'm getting past at the next corner, or, YOU'RE IN THE BARRIERS MATE !!!

It looks interesting what your planing Mr. O.

I was thinking about the Pheonix street-circuit, and thought later, if I was doing some of the 90 deg. corners; I might use a side-swipe on each end of a 90 deg. squeeze R1.
Wondered if you could incorporate a squeeze 180 deg. as well for variety.

I hadn't realy thought about 'cutting' track sections untill recently, but a bit of cutting in your situation could pay dividends.
eg. 'custom cut' bits for your single-lane section.
You don't even have to cut the connector pieces, just the plastic-lane parts, to get more possibilitys.

Another good tip; if you want to gain height rapidly without track bending or sharp transitions; is to use lots of the very shortest track sections ( even if the geometry doesn't need it ).
eg. 4 quarter straights, instead of a whole one; & lots of 22.5 deg. bend sections instead of 45 deg. ones.
I'm sure you get what I mean, It lets you increase the % gradient more smoothly.

You should start a thread in 'tracks & scenery' to thrash out some ideas ( & talk about FAST CARS ! ).
I guess you might have the usual plan in mind, to start a bit of building when the weather gets a bit better in the spring.
I know I do; although strangely enough it was 12 C here today, last year it was about -5 C !!! Brrrrrrr.....

If you start a thread I'll drop in and waffle on about hair-pins & hill-climbs & 917's no end at all !!!



P.S. I don't know if you use UR3 software, but it is exellent for bashing around a few ideas real quick on a complicated arrangement like yours.

Yeah... reversing the 'Y's gives much better racing-line in/out of the corners, I do this with side-swipes & X-overs.

Hi Christian

Just start a thread & MESS UP !!! ( although I'm sure you won't !!! ).

Just got myself a 917, woooo.... track report soon, when the mail-man gets here !!!

I don't know what 'track power' software is ?

3D to me at any rate is a waste of time.

UR3.0 software is what I use, & would recomend; does 3D as well ( personaly only use 2D though ).

Mr. O I need a place for my hairpin & Targa photos; PLEASE start your thread SOON; I wanna wax about HAIRPINS !!!

Could have a pin track brewing here too !!!

Hi Christian


I just meant I don't use the UR3 3d mode myself.
Could be good for some people though.

I know what you mean about realising the possibilitys during construction.
Untill this summer ( & UR3 ) all my past tracks were done with 'paper templates' of R1's R2's etc.

Having made quite a few of these 'real paper' drawings, you get a great feel for what's possible.
Laying the track out, has actualy caused no changes in the designs, other than borders & barriers which you gotta put down after driving anyhow.

I can see that your Targa hairpins will be a major challenge, & you just gotta lay 'em on the wood to get it right.

Just re-drew my 'Suzuka Japanese GP' circuit for the new larger room.


Still love MRW as is, but this version of Suzuka ( LOT'S OF R1's ), which I made a smaller version of previously, could be next-up.
Maybe this summer.
