2-Suspension
3-Solid Axle and Differential
4-Bulkheads & Drivetrain
5-Driveshaft (ECS & CVD)
6-Front & Rear Suspension
7-Tweak
8-Anti-Roll Bar

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

all Loctite thread lock products are anaerobic. Meaning they cure/set in the absences of air. I really don't think grease right after setting the screw is going to hinder the setting of the screw. I worked in the automotive field for over 30 years. and in building engines where loctite is used, oil is used right after for lubes also.

I am just curious what is you guys experience on aftermarket front swing shafts>?
I am trying to choose one of the following:
3 racing:
http://www.rcmart.com/3racing-t301-d...=595_1077_1571
Spec r:
http://www.rcmart.com/spec-spr001p8x...=595_1077_1571
yeah racing:
http://www.rcmart.com/drive-shaft-xr...=595_1077_1571

http://www.rcmart.com/yeah-racing-sp...=595_1077_1571

I just hope these don't snap upon impact.
Is it is worth paying double or tripple for a set of Hudys?


I am also curious, if you guys like the feel of font gear diff with million oil in it?

The 16 kit comes with ecs standard?

But the quality of the new super strong ecs are fantastic and supremely strong! (Other version are good as well just not as strong ).

I just want to chime in on the ECS and threadlocker discussion.

I recommend Loctite 243 or any surface-insensitive threadlock when building the outdrives. 243 is different than the standard 242 formula as it has oil-resistant properties.

http://us.henkel-adhesives-blog.com/...locker-Basics/

With 243 it is not necessary to have perfectly clean threads on the set screws and outdrive couplings.

Ya, they are standard.
Mine are very slightly bent after a few days of use.
So I am planning to find replacements right now.

I have all of them except the SSK, so I can't speak for them. The Hudy ones are superior to all of them, but a good second best are the new Yeah racing ones. If you want to save the $, go with them.

I only use the Purple loctite on RC stuff. Its made for small metric size screws and not as harsh as blue. Its hard to find though but works awesome.

The ARS system doesn't work well in low traction, so you probably won't find a setup for it. I tried it twice in medium traction and it had no rear grip.

The only time I've really seen it work well was at the Hudy arena, which is super-smooth and had 300 people laying rubber down.

Anywhere I can get an aluminum chassis for the 16 car? Have one showing up tomorrow (Thanks EA!) and would like to build it right in. Avid is out of stock and the Xray one isn't available yet.
