running T1R for first time

[Nick Hudson]

hi all,

i am running my shiny new T1R indoors on carpet tomorrow for the first time.
i assume the kit setup is a good place to start but was wondering whether any of you have any wise words on setup.
i am running a matrix 19t stock and sorex 24R rubbers (i had these on my losi xxx-s g+ and they work great).

btw - it was the best car i have ever built - miles ahead of the the other kits in my garage :D ;D

It's pretty good out of the box. The only differences I've made to mine are;

1 degree rear toe-in
1 degree front toe-out
Purple front springs
Violet rear springs
40wt with three holes open front and rear damping.

I don't think you'll be disappointed though... ;D

[Nick Hudson]

is that indoors on carpet ?

[university_dave]

Yes, running on Carpet Dragons with Schuey blue foam inserts on 26mm wheels.

My outdoors setup is the same but with 4 holes open in the shocks and softer springs. If it's hot/high grip then violet front and blue rears, if cold/low traction then blue fronts and white rears.

I dont think one degree rear toe in is particularly wise. Would make the car incredibly hard to drive, T1R comes with 3 degrees as standard

[Doomanic]

I run completely kit standard except for the rear shocks, which I have moved out one hole on the tower.
Seems pretty good, just a bit of lift off oversteer, but the Carpet Dragons I use don't exactly have much sidebite! ::)

Don't knock it until you've tried it. If I thought, or indeed found, it hard to drive would I really be suggesting it?

[Petermarkphillips]

Well one degree should make it incredibly hard to turn into a corner, have tried it, it was hopeless. 2 degrees at rear is the minimum you should ever run on Xray

[university_dave]

That's interesting, I've always found (and seen it written) that more rear toe-in gives you LESS turn in and makes the car more stable.

I would never suggest an entire setup, it won't suit everyone. I found 3 degrees horrible for example, the car just wouldn't steer. If you look at my post I listed some of the things I'd done. It is never a good idea to change more than one variable at once, and definitely never a good idea to slavishly copy someone else setup.

[Nick Hudson]

thanks for all the replys.

i will let you know how i get on - it will be interesting to compare the laptimes with my xxx-s g+.

i ran 3deg toe in on my losi and it had loads of rear end grip (maybe a tad too much).

anyone tried the 2.5mm carbon upper deck yet ?

nick

[Nick Hudson]

well - what can i say !!

ran my t1r for the first time last night and i am amazed - there's no other way to put it !! ;D ;D

bog standard, kit setup - it rocks !

maybe i will try reducing the anti-dive to 0deg to get more off-power turn-in but that's about it.

it also stayed in one piece - which was nice

anyone wanna buy a xxx-s g+ ??

More rear toe-in gives less rear grip, more rear stability. I find that less than 2 degrees makes the car wild hard to get into the corner, sure you will get more steering, but by compromising the overall handling of car.

I am not running the T1R chassis anymore, as it aint as fast.

[university_dave]

anyone tried the 2.5mm carbon upper deck yet ?

nick


Stole it from my T1 before I sold it ;)

Works really well on carpet, I've even got the original T1 carbon chassis to try as soon as I get the money together for the T1 servo posts and cell straps.

[steven bough]

Im thinking of selling my FT TC3 to buy the T1R-has i want a car thats easy to driven -and easy to set up-has i not the best at setting my TC3 up-Do you people that have T1R find it a easy car to get on with-And is it worth me selling my Tc3 to get one of these?

[university_dave]

Well you're in the wrong place to get an objective answer!!!

I would have said you'd get on well with the T1R right out of the box. I think the car as a whole is easier to set up than the TC3 and goes better too (brother owns a TC3 so I do have experience of them).

[Doomanic]

I've had a TC3 Team, now got a T1R.
I have no intention of going back! :o

Care you elaborate?

Thinking about trading in the Ol' TC3 FT for a X-ray Raycer.

[Doomanic]

The T1R is far better engineered which makes it much easier to build and it appears to be stronger.
I built mine in the shop 4 hours and that included answering the phone and matching cells!

The TC3 is not a bad car, but I think the X-Ray is better.
It only needed a couple of pairs of springs and a change on shock mounting position to get it sorted on carpet.
The TC needed different oil, camberlink positions and springs to get that close to sorted, and it still wasn't as good on Carpet Dragons.

[Joost van Leeuwen]

That was not the answer I was hoping for, it looks like I need to go for an X-ray too ;D

[steven bough]

I just want a car that is easy to set-up.I find my TC3 you need a bit of knowledge on how to set it up for each track-im hoping the T1R is a car that you can chuck on most tracks & would handle well..

[Nick Hudson]

i have run my T1R for a while now and it responds well to changing track conditions. running zero squat and anti-dive, -2 deg camber all round, 2 hole open/1 hole open R/F dampers on 30wt, kit springs, seems good on rubbers - personal choice of course....

[Chris Thompson]

i'm looking forward to getting my t1r, but are there any hop-ups that any one recommends that improve performance, and i've been looking at the short wishbones thread and they seem like the one to get, but are there any others?

[Chris Thompson]

ok i got my t1r and its been built with the electrics installed. so i decided to turn it on and give it a whirl and it was good although i havent raced it yet (gotta wait till sunday) but when i put it on the table with the wheels off the table and i turned the wheels one way and slowly revved the moter and when it got to a certain speed the front belt would virbrate and virbrate the whole car, it's the same when i turn it the other way.

i think this may be because it hasn't been run in. but also the front belt is twisted a bit again i think it would striaghten out after a few runs and maybe stop the car vibrating.

just wondering if anyone else has had this problem and whether its got better?

thanks

[ldebackker]

well, it's normal for your belt to vibrate, but your whole car... ???

maybe because it's too tight, I don't know actually.

[Chris Thompson]

it only happens when all the wheels are off the ground!

[Robfo]

My mission did the same thing, i wouldnt worry unless the car does strange things at high speed. I'll have a look at my evo2 tomorrow and tell you if it does it aswell.

[Chris Thompson]

it might have something to do with the tension of the belts or something, but i don't know?

[Matt Brewerton]

What you need to check is that you don't have too much steering throw on the car. This can sometimes cause the driveshaft to rub the axle very slightly when on full lock which results in the vibrations. If the vibrations continue then it may be worth tightening the belts a little and seeing if this helps.

Matt

[Chris Thompson]

i cant remember but i check in the morning but i think it started to virbrate before it got to full lock, but like i say i'll try it in the morning. and i'll ask some people at the race meeting for advice

[Chris Thompson]

yep still doing it, but i dont it affected its performance as it was flyin after a couple of minor set-up changes.

xray all the way!

[Robfo]

Mine doesn't do it chris, what did the other xray racers say who got a look at it?

[Chris Thompson]

it was a bit quiet as alot of the drivers went to the carpet masters so there wasn't any other xray drivers!

i'm going to get a new front belt to see if it helps, as the one thats in is a little twisted,

[steven bough]

Doomonic if you read this thread-Did you manage to get rid of the Oversteer you had when you first used the car? if so how did you do it-What carpet set-up are you using now you have used the car more??

Regards

Steve

[steven bough]

?????Any one?????

Ive been using the wire front 2mm anti roll bar-do you think it could be to stiff And is actually making the reaR tyres have to much presure,which is causing them to slide.Also my tyres are screaching when cornering,i once read some advice about how to stop it etc ,has it means the car is not set up correct (Caint actually remember)the inns & outs

Im not sure if to buy the blade type front anti roll bar to use instead of the wire type-but the cost is putting me off..

Also what droop settings do you use for the Xray T1R (27t stock)- on carpet(ive only got the TC3 droop gauge)

Also when looking at set up sheets for the T1R do you measure from the front & rear block screws??-
-just at the rear the screw socket hole sticks out at least 5mm.I just need to understand if you etc measure from the block screw holes?? (if that makes sence) ???

!!Respect to you Xray drivers!!
Stevie

[steven bough]

Also ui copied a mates set up for carpet when i built the car And ive only used it at two meetings,The car was good exsept for the off-power oversteer.
But i cain't make my mind up if to copy the kit st'd set up,so i can understand what things do-i.e anti squat,kick up etc,has ive not played around with them for myself.But It probably means that the car wil not be has good has it is now,But a mate said its better to find my own personal set-up rather than others..
Im contadicting myself here but what set up do you use for carpet (27t)

Resect 8)
Stevie

[cbcbcb]

I use the following set up with T27s on carpet:

As kit, except
Two degrees rear tow-in
Front upper shocks mounted in position 3
Rear upper shocks mounted in position 4
Rear pistons: 3 holes open

To set the droop screws I do the following:
loosen off the droop screws
set the ride height with the shock collars
Lift the car off the ground. The shocks will extend so that the springs are not held in position
Tighten the droop screws until the springs are held in place, but are not compressed when the shocks are fully extended.

The kit set up should make the car driveable on carpet, if not, perhaps you need to check the shocks and that the suspension is free.

[Chris Thompson]

i'll be running my t1r at stafford this sunday and hopefully will be running 19 turn (reedy), so i would like to know what gearing other people use as i have little experience with running on carpet?

also is it a good idea to run a front anti roll bar (blade) on carpet?

Chris

[steven bough]

The set up i got of a mate uses the blade on carpet,And he does very good with it

[rice98w]

this mate, its sharpey right?

his car was pretty good by the end of tonight, he TQ'd by about 3 seconds.

its worth bearing in mind though, that his T1r isnt standard, different wishbones, shock towers etc, they all add up... but, if you want your T1r to handle at WB, definately take note of daves setup ;)

[ian plimmer]

lol lol lol lol lol matt youve not seen mine yet then

[rice98w]

alas not, WB is the place to run it around our area for stock, its soooo close, clean and a good atmosphere..

you doing c.a.r.s tonight? stock or 12th?


you should come upto WB on a friday one week, or a sunday meet. ;)

[Chris Thompson]

so any advice on gearing then?

[rice98w]

"chris"- no, sorry, try the stock motor forum

stevie, your car looked a bit twitchy by the end of tonight, what did you change?

[steven bough]

i didn't alter much-
i think i was messing around with the diffs,has i have just put the low ratio set on-and didn't run the diffs in-

i think on saturday (has ive raced today Sun at greasly (7 rounds :o) -
but sat i could have done with a anti roll bar on the front-the week before i used the wire normal type & didn't really like it,it was the 2mm one and i think it was to stiff causing the rear to brake loose because of to much presure on the rear.

But ive now got the Blade type which ive not put on yet-but it looks better because it is very tune-able-but it dont fit the new short wish bones-which i was going to buy,so ill leave it st'd for a bit..

Sharpie raced today with a harder set-up than me & with S/wishbones but it took him about 6 rounds to get it going well,but when he did it looked loads better-

I feel my T1r is Too Smouth,but sharpies looked a bit more aggresive.

Also i had new D20 treaded sat so that might had made it a bit twitchy-but my main problem is >:( oversteer >:( Mainly lift off-
so i put 6deg caster which helped but then it oversteer out of corner which was better than in. ??? ??? >:(
So thats were im at trying to tame the rear,Has Xrays seem to have loads of steering!! >:( ;)

Thats my journal for the day...

so you are going to w/bridgford on Fridays!
The next friday i get free ive promised Plimmer ill go to his club.... 8)

(me & Sharpie are doing the BRCA 27t class this summer you should do it with us-(mat & Ian)

Doomanic if you read this thread-Did you manage to get rid of the Oversteer you had when you first used the car? if so how did you do it-What carpet set-up are you using now you have used the car more??

Hi Steven,
Sorry, not read this for a while.
Here is the set up I used yesterday on a very slippery carpet track.

Front
30 wt, 3 hole fixed pistons, light blue springs.
Middle hole on tower.
1 deg toe-in per side.
Camber link on middle hole.
0.5 deg camber.
3 deg anti-dive.
3 deg castor blocks.
Short wishbones.
Std ackerman settings.

Rear
30 wt, 3 hole fixed pistons, white springs.
Middle hole on tower.
Inside hole on wishbones.
3 deg toe-in per side.
Camber link outer hole on hubs.
1 deg camber.
3 deg anti-squat.
Short wishbones.

With this set up the car was very neutral.
It had lost most, but not all pwer-on understeer, but still had good turn in on or off the throttle.

[steven bough]

DooM
I think im going to try your set-up for next weeks racing.as ive now got the s/wishbones.
Regards the above set-up-what would you change for a medium grip carpet track?

Thanks

Steve

[Doomanic]

To Be honest, I have found that set up to work on all three tracks I have tried it on.
Without watching what the car is doing, I wouldn't know what changes to suggest, as all changes affect more than one aspect of the handling.

[Chris Thompson]

i think a good read of the set-up book would be a good place to start

[Luke Hobson]

yeah i have found tghat set up book extreemly usefull already, i've been running mine for 3 weeks now and all i changed to get it nail at my local track is the front oil and the reait shokc position at the tower.
impressed?? damn right i am
