2-Suspension
3-Solid Axle and Differential
4-Bulkheads & Drivetrain
5-Driveshaft (ECS & CVD)

New Graphite Hubs:
Xray have recently released some additional Graphite hubs for the T4 lineup. The 4° Graphite C-Hub has been out for some time and is known to improve steering on entry, and in general makes the car turn better. This has been the go-to c-hub on asphalt for many on the Xray team, though it is not needed on high bite carpet. The Graphite rear hub tends to make the car more stable, especially on corner entry. We are still working on gathering input on the new Graphite steering block, but for the moment feel that it should improve steering response. All Graphite parts are approximately 1g lighter than the Hard or Medium options.

Option Parts to consider:
XRA301196 T4 Graphite Upper Deck 1.6mm V2
XRA301226 Foam Bumper – Hard - highly recommend
XRA302165 Composite Front Suspension Arm 2-Hole – Hard
XRA302169 Composite Front Suspension Arm 1-Hole – Graphite
XRA302803 1.3mm Front Anti-Roll Bar
XRA303169 Composite Rear Suspension Arm 1-Hole – Graphite
XRA303802 1.2mm Rear Anti-Roll Bar
XRA305137 Steel Solid Axle Driveshaft Adapters - HUDY Spring Steel - highly recommend
XRA305242 Composite Drive Shaft Replacement Cap 3.5mm – Orange – Strong (QTY 4)
XRA305351 Aluminum Wheel Hub – Offset “-0.75mm” – Black (QTY 2)
XRA306191 T4 Graphite + Aluminum Fully Adjustable Battery Holder
XRA308264 4S Spring-Set Progressive C=2.5-2.8 (QTY 2)
XRA308276 4S Spring-Set C=2.7 (QTY 2)
XRA308286 4S Spring-Set C=2.6 (QTY 2)
Specific to Asphalt:
XRA302383 Composite C-Hub Right – 4* - Graphite (ECS)
XRA302384 Composite C-Hub Left – 4* - Graphite (ECS)
XRA308039 Aluminum Progressive Shock System – Set (QTY 2)

Specific to Carpet:

XRA301141 T4 Aluminum Flex Chassis 2mm
XRA302375 Composite C-Hub Right – 6* - Hard ***Modification may be required if they don't have the "ECS" stamp.

XRA302376 Composite C-Hub Left – 6* - Hard ***Modification may be required if they don't have the "ECS" stamp.

XRA303711-O Aluminum Rear Lower Suspension Holder – Front – RF

Thanks for quick replays! As it looks it's 50/50 on doing or not Anyway, I did CA thing. Wasn't that difficult, only in some places glue went not just on edge but tiny bit on surface as well. And as I wiped it off only when did whole chases it was already hard enough not to get all of it off. Anyway, it is almost unnoticeable visually. And I guess nothing is attached so close to the side that it can throw off some kind of alignment. Edge itself looks cool - much darker black.

But I totally see other side as well - quality of carbon part sides where very good, perfectly smooth. So, most probably it would last also without CA treatment.

I personally found it is more important to sand the edges then CA them. It is harder to delaminate the chassis if it has round edges!

Acetone removes CA. Put some acetone on a paper towel and start rubbing. It will come off in 10 seconds.

I have been using CA from locktite with a brush aplicator it works great, round your edges and apply. Watch the acetone it cleans CA great also can soften epoxy.

Hi Guys, Can anyone tell me the length of the shocks on the 2016 car please (From the centre of each ball connector).

Thanks

They are the same length they have been since the short shocks came out. They will fit right on your Tamiya with some custom shock towers just like they did Marc's and Krapps.

Thanks for that. So my black SLP's are just the same as the new 16 versions. I just assumed by the hype on the X-ray spec sheet that they were different.

Xray has had the same shocks since they introduced the short ones a few years ago. The new black ones are the same size as well.

I spotted in Olly's set-up this remark ''New Alu Chassis with cuts''!

I suspect the word ''new'' is for the '16 version but what does he mean by cuts?

Some clue from the guy's that were at the sight?

For those that have the Avid aluminum chassis how do you mount your electronics? To it seems that there is not enough area to hold them on the chassis unless you mount them like usual and try to clean out the dirt/stone buildup between runs.

No its a new Xray option chassis that they made while we were at Hudy practicing for the ETS race. It has went into production but I would bet its a few months from hitting the stores world wide.

Though it still had quite large cutouts.

Was the idea to make something inbetween the alu and the carbon chassis for flex?
Could a thicker carbon chassis do the job?

At least from what I hear of the US team drivers around me (running the Avid chassis, but very similar) its more about weight placement and helping to prevent traction roll. There is a stiffness difference of course, but the added weight down low helps on carpet. He is also running the 1.5mm Avid top deck along with it. He has 4 cars, 2 with aluminum chassis for carpet, and two with carbon chassis for asphalt...

Haven't tried it myself, but thats what I was told by someone who is pretty darn fast around here...
