Try the new adjustable battery holder #306188 , or you can glue some plastic pieces onto the battery backstops to minimize the play.

Alright thank u.. Another question how do you cure the battery play?


I use a small piece of double sided tape on each back stop, that is just enough thikness and the battery stays firm in place (maybe Ale solution with a plastic piece is better since it will be even more firm, to secure the battery invards in the car I use a 5gram balance weight. I need to weight the car down anyways and the placement is just perfect in the middle of the car.. My battery cannot move at all with this simple solutions.

You have to cut the plastic pieces yourself. Or just use plastic 3mm shims which are included in the kit.

All bodyposts come in the same full length. You have to cut them to the desired length. If done with a cutting disc from a dremel, and then a bit of afterwork (polishing) they will look like they are factory cut.

Hey there,

to achieve a certain ratio, it is possible to get there with different combinations of spur gear and pinions.

Is there a recomondations to use more higher or more lower amount of teeth? When using spur gears > 94 teeth, it is scratching the setupboard when I push the car down for a quick tweak test.
In certain setup sheets, I noticed spur gears >100 teeth.
Is there a reason for that?

I think you mean setups where 64dp spurs are used.
The largest 48dp spur I can fit is 86t, anything bigger and it sticks down below the chassis.

I run 64p. 114 works but I wouldn't try a larger one.

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


I seen that wat i ask for is finally realised, thanks for willing to do so.
Of course i buyed this updated layshaft bulkheads, and it works great.
Thanks again

Ed

Hi guys,

I've been running the T4 since November and I'm pretty happy with it, another great XRAY.

I have taken delivey of a set of the new Kevlar Low friction belts and would like to know, how well will these belts perform with a Modified motor (x40 4.5)?

Notices from Italy, the new white belts are very performed indipendently from armature you use.

It look like it, but consider the the construction and where it differ it must be another cause.
Lookin at my home track all cars are more or less equal till the point someone has more or less
succes with a different set up or tyre additive.
But at the top (world) there are 4 or five drivers who make the difference and no one is driving
with Xray, if they do it shows that xray is equal.

Hi, I just bought a T4 and I haven't raced it yet. I will probably keep it for the start of the indoors season (Essex winter series). So far I was racing with a 2011 T3.

I know there is a bumper upper holder for better chassis protection. Is there anything else that you would suggest I should buy? Any advice is welcome.

The low friction belts works awesome both in modified and stock classes! The drivetrain is freer and the lifetime is longer, especially of the rear belt.
