XRAY - Model racing cars

My front right tire is wearing worse then the others, what causes this ?

I have the kit setup on the car only thing I changed was I reversed the springs I put the 2.7 on the rear.

Some one suggested a different roll center -75?

I race on asphalt

Fastest corners are left turns...

Could any suggest a good outdoor asphalt setup to try?

What will the 2.5 - 2.8 progressive springs do up front ?

Thanks Skiddens! I edited the post.

hi Paul
if i narrow the front track width what/when would i benefit from it? currently i run 2mm ff and 1.5 fr i just changed it to 1.0 ff and .5 fr?

ok ,who ever abducted paul please bring him back,i need answers

hi paul when you get back can you take a look at this please,thanks
ok ,started the race day with a car that was sweet to drive,after 1 round quali im 7th,so the rest of the day im trying to go faster,but this is where it all went wrong,the rear became very loose as the temps came up,i took the 1mm inner link shim off and although a little better its still loose,tried a 1.3 rear bar,still no good,went from 2.7 to 2.6 helped alot (i posted a faster time)but 3/4 mins in the same again,i tried standing them up,laying them down but just couldnt get the rear to grip,was i overheating the tyres? im not sure as i ran a set cold and it was still loose and didnt get better as they warmed,so what should be done and why,thanks

Hi Paul. Our weekend fun track is a concrete parking lot with low-medium traction and a bit bumpy for which i need to raise ride height or else ill risk bottoming out the car. I would like to know the effects of raising the ride height setting to 8-9mm with the T4'14 asphalt base setup? Do i need to change settings to compensate this difference since in every T4 setup that i have browsed through so far, ride height is set at 5-6mm or even lower?

I've ran the T4'14 at 13.5 boosted with FDR of 5.91 for two weekends now; using the base setup but with ride height set at 8f/8.5r; 3f/3r droop over ride height; 2.5f/2.0r springs using 4h 1.1 f/ 3h 1.1 piston r with 100% rebound and 45WT oil for all shocks; 500kf/1kr gear diff oil; Sorex 36R; its really easy to drive and responsive but i do experience oversteer which i blamed my driving skills for that (only a few months in RC)... late in slowing down before turns; still very minimal chassis wear with the current setup . Fastest lap time is 12s; i'm usually last with average lap time of 13+s

Thanks in advance.

Hi Paul thanks for answering and providing a great advice. I'll try lowering ride height with the camber and dampening changes as soon as this coming Sunday, if weather permits . Let you know how it goes. Good luck to you too!

Well had my first experience of running an X Ray this last weekend and have to say it was really good, very pleased with the handling and smoothness of the car. However I have had one small problem, twice during the day the frony belt came off the pulley. I am running it loose(ish) but not very loose. So the question is, what tension should I be running the belt at, tight, very tight, loose or very loose, and is there any other reason that might account for the belt coming off.

Running 17.5 Blinky so would assume not quite so necessary to run really tight. However will tighten up slightly and see what happens.

Does the optional belt tensioner work?

Might well have been stones but who can tell afterwards?
