XRAY - Model racing cars

I didn't find in the bag 01.2 an important screw to fix the bodies of the differential, I'm writing an email to you for the details.

Thanks for your helping!

Colin,

it depends on the track layout. If there are many chicanes and 180 corners, I would use 1.1 piston as the car rolls less and quicker change direction and stays more flat. With long sweepers, you can use 1.2. this would also provide more traction. But generally, I would suggest to start with basic shock setting from kit which is made for low-medium traction.

I notice all the T4 setups I have seen so far have 2000cSt oil in the rear diff.

I haven't run my car yet but immediately put 1000cSt in it as with the T3'11 and '12 I found 700cSt too thin. In fact I ended up using 3000cSt in the end.

What have the drivers found when using thinner or thicker oils i the gear diff?

Thanks
Skiddins

Hi Martin as we hire our hall our track lay out changes every week so it is never the same so at the moment i'm in the hunt to get the best setting for all round best grip

Best Regards Colin

Hi Martin,
it seems as if the e-clipses for the shock shafts cover up the holes in the pistons a little bit.
Doesn`t that influence the oil flow?
The e-clipses supplied with the kit are larger than the ones mentioned in the manual (965023/ 2.3). These would otherwise be to small to fit the shock shafts.

Hello,
in comparison with t3 around upper holder, I have seen that there is too much clearance between bulkheads and upper holder (is there enough resistance after crash?) Have you make some tests I imagine...

Thank you!

Just noticed there is a problem with the part number for the 1.3mm rear roll bar in the manual on page 21.

Do you know when the option springs will start shipping?

Thanks
Skiddins

You are correct, thank you for the info. XRAY will make the correction.

The new optional springs:

308264 - C=2.5-2.8 - already available
308274 - C=2.3 - now in packing, available within few days
308275 - C=2.5 - already available
308277 - C=2.9 - in production

I suggest you will contact your national distributor who will let you know where and how to get them.

Hello

I've now done 2 meetings with my new T4 & have found it a little tail happy I have set the car to the basic carpet set up apart from the oils & they are as follows

Rear Diff 600cst instead of 700 supplied with kit
All shocks 40wt instead of 350cst supplied in kit

I have the front diff in the raised position so locking tab in down & the rear diff in the lowered position so locking tab up

I would say the carpet we use is low to med traction & track condition is mixed as track lay out changes each week

Thanks Allan

I would try what Skiddins suggest here:

Hi Martin, I would also kindly like to ask- IN asphalt with long-medium sweeping corners, Whats the easiest way to make my T4 slightly understeer in the first initial corner entry but really stick in the mid corner and exit with on power steering . Ive noticed with the stock set-up I have to brake really hard at the first corner entry to make it turn and after I put the throttle on it goes out of the mid corner and exit

If i dont put on the brakes hard, it will go out of the corner

Hi alex thank you for your reply. I will try interchanging the shocks. Should I remove the shims from the Alu steering plate only or both from the alu steering plate and the ball end?

Hi, I just ran my T4 for the first time last night. I stepped up from a 008 chassis so I didn't have the correct spur and pinion combo and I wanted to know what spur and pinion would fit in the car to give me a final drive in the low 4s?
