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!

Ehehehehhe...good news by this topic...the new bumper upper holder :lol:

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?

I find that the 100t 64P gear is the best for 13.5 and 17.5. In 17.5 I am running a 3.6 and I am able to achieve that with a 100/52. You should be able to fit a FDR of 4.0 just fine with the 100T.

This is a nice option part for your T3 car which allows for different roll center positions to be used!

Thanks Alex, after testing the car we noticed that the output of the gas is very unusual curved sobrevirador.Tenemos put the asphalt factory setup minus differential in the lowest position

Hi Alex,
why did you use raised steering posts in the las races. Just for bumpsteer? Is it different in comparison to using shims on the steering blocks?

Question for Martin Hudy.
Hi Martin I like my T4 very much it handles OK.
The only thing what should be changed IMO is that the layshaft bulkheads must have a closed
bearing chamber instead of a sleeve.
If so I can remove all the screws on the layshaft bulkheads with should give more chassis flex
when needed without demolished the spurgear special under breaking (mod) the spurgear
is moved upwards when the layshaft screws are out.
This wil hopefully solved the problem for Adrian Berntsen(he is quick but need to finnish the run), because he is driving with all layshaft screws removed, I drive my car with this set-up and it work very well for me and others with this set-up.
Hope you understand me and make the car quicker and quicker.

Best regards

Ed

It's not same as adding bumpsteer as the raised steering also changes flex characteristics for the steering itself. For some reason it gives a smoother feeling and more cornerspeed.

Can someone please explain the motor holder standard or option setting on the T4? I am still running the T3 2012 but am curious to know if this is an option part or a setting on the new car?

Hi Skiddins
I have ordered the 1.6, not yet received.

I have already made the lay-shaft bhd's so that the
bearing stay's in position, like the 2012.
This was the right thing to do for make a new track record.
I make it for a fellow racer as well so he is also able to take the
track record (13.5 stock) on next saturday
Btw the track record is now more than 0.25 quicker by only switch
from t32012 to t4.
Have you tried this 1.6 TD or? Let me know if you have.
Thanks

Ed

I have tried the 1.6 top deck, but only on carpet, it helped in low grip but lost lap time when the grip started to come up.

Thanks, maybe it works for me because the track where we race is medium grip.

Hi all

We had our first South African national event that took place this past weekend. I moved over to the Xray T4 in the beginning of Feb , and was not sure what the outcome would be. That being said , I am pleased to say that I won the 17.5 t boosted class. Having qualified third , it took some consistent driving and putting some pressure on the leaders that gave me the win. I must admit , this car is a dream to drive and this was with the asphalt setup with minor changes. I managed to do 15.5 sec fastest lap with a 15.9 sec average. I LOVE this car. :D

I changed to 40 wt oil all round. I replaced the gear diff oil to 2000. Camber 2 in front , 1.5 at the back. 2.5 toe-in at the back and 2mm shim under the steering and that was it. This was on asphalt

You should mount it on top of the kit battery backstops as shown in this picture: http://www.teamxray.com/teamxray/showim ... 613f1604ad
