XRAY - Model racing cars

First Question
Q) would it be to my advantage to use the 3.5mm chassis indoors,carpet,T27 tyres

2nd Q) do i still need the wide top deck to make good use of the extra ridgidety

I run the std FK indoors at the mo, very happy with the way it transfers around the corners

PS
I want to progress forwards with tuning not backwards, like my driving

It definitely would. The standard chassis is great, but the thick chassis gives even more consistent grip and makes the car more reactive.



You don't necessarily need the wide top deck, the standard top deck and the "old" thick top deck work fine as well, giving slightly less rigidity. The wide top deck does improve the car even further especially when running foam tyres.

BTW, it is best if you post your questions under a new topic. This topic is only intended to identify the forum.

Since this is a general forum, Mr Jolly should be able to ask any question he likes.

Yes but it makes sense to have seperate threads for seperate quastions, were not on rctech now

I agree, I was not referring to the forum, but to the topic. This way it is harder for everyone to follow the discussions. Questions like those from Mr Jolly are relevant to everyone.

I see what you mean Tony, yokomo usa run a forum like you might want it to & it is confusing,you end up chasing around trying to find the topic that might be suited to you or the problem.

Then you have RCTECH.NET you go straight to the thread that you are after ,ask a question then you get good help & advice from anybody, & very rarely get `this question has been asked before do a search`you get answers instead

And before you say that does`nt work on a forum,How many users has RCTECH have `A Few thousand` that`s how many

How many users have rcracecrap have, diddly squat, that`s how many.

Me thinks that the chassis question is a general one,nothing special to warrent it`s own topic,which would run out of steam pretty quickly if it did

You are assuming that you will not get a response. While this may happen in some cases (as it does on RCTech), I believe XRay has a good track record on myTSN and have every intention to keep the service at the same high level and improve where possible.

Focussing a topic on a specific discussion helps us in this as it is easier for us to find earlier discussions and answers. We can then provide links or copy-paste the answers, whatever makes the most sense in the given situation.

As to the "sticky" Mario put in this forum, he was referring to the forum, not the topic started with his sticky.

Rcracecrap Nice

I must admit i di assume alot (according to my wife)
Next Q
how much thicker on the oil front using rubber tyres on carpet, At the mo i use the kit 30w every where i just click the dampers around to stiffen or soften(i`m lazy), is good alternative then changing oil all the time to get a nice setup?

I usually run 30W as well. Only if grip becomes high on the bigger events is it sometimes a good idea to consider 35 or 40 weight. In this case lazyness is a blessing

Next Q
The rear roll centre i have it in the lower hole at the mo,,,Is this a good idea on carpet?

Or would running in the top holes be better

On carpet with t27`s rubber

wut would be a good setup with the t1r with a warpspeed chassis on carpet with rubbers, i have a oneway up front, or would a spool be better? I will be racing stock

MR JOLLY, the upper rear rollcentre positions will give you a lower roll centre, i i would stay away from using them as they can give too much roll sometimes.

the thick chassis will give less grip due to there being less twist in the chassis, but when you compensate for the loss of grip with softer rear suspension the it will be more consistant.

That sounds good to me,providing the holes i am on at the mo (lower) are the ones to stay in?yes.

Next Q
The front camber link was in the kit hole(shock tower) & every bleeding time i went to adjust it from 1.5 degree camber to say less/more canber it keeps on twisting off the inner link,i ended up using long nose pliers to hold the inner ball end while i adjusted the link,Well this got right up my goat, i thought nuts to this i moved the inner position in one on the shock tower & hey presto i can adjust the link.

Has anybody else have this problem?

I assume you are talking about the holes for the lower suspension arms right? The higher positions give a higher roll center and thus less chassis roll. With rubber tyres your main problem will usually be a push on carpet. Therefore we usually run the upper holes and sometimes the middle if the rear feels too unstable. With foam tyres you will have great front end grip and should stay clear of the upper position and use the lower or middle position instead.

I have just brought the 3.5mm chassis & why oh why have x-ray NOT chamfered the battery slots for us lazy people , i am going to get blisters on my smooth as a baby`s bum hands
So with all the drilling,milling,dicing,slicing,honeing,cutting,slotting,so where`s the chamfering

had the front link problem you did MR JOLLY, it just took time for the plastic to lose its grip on the turnbuckle. What i said about the rollcentres applys to the upper link.

I have just read all my post`s & it seems that i`m moaning about this,moaning about that,did`nt do this,did`nt do that ,i`ll stop now .
tony
The roll centre issues is with the three holes in the alloy bulk head on the rear
