Sven's 4-TEC 2.0 Rally
 

Hi there, my name is Sven.

I'm new to this forum, but not new to RC :) Been racing/bashing RC cars for over 10 years now. Since i'm into rc rallying and this forum seems to be most active in rally topics i decided to join and post my build here "thumbsup"

I own multiple rc rally vehicles:
Traxxas Rally 1/10 (the 'Slash' version)
Kyosho DRX VE
Tamiya XV-01 Long Damper spec
HPI WR8 Flux

Aaaand.. the Traxxas 4-tec 2.0 :mrgreen:

I choose this car for some reasons:
- Part support is great in my area
- Raised front bumper
- Solid chassis
- Sealed driveline


So now the build :)
First thing to do is cut away parts of the chassis so the suspension arms have more free room

And some grinding on the front arms to create more space for the C-hub

Difference stock vs modded

The increases ride height made that the steering rods hit the chassis, so this part also needed some cutting/grinding

The stock shocks are short with not much stroke so I ordered some longer ones :mrgreen:

No we have some more ride height! The ride height is actually al little more than my XV-01 long damper ;-)

The chassis bottoms out before the shocks do! Perfect for not landing flat after a jump ;-)

I ordered the Traxxas 4-tec sway bar kit, but due the increased rideheight they hit the drivecups..

Some bending on the sway bars should solve this. Stock vs bended :)

Problem solved :D The sway bars work perfectly now

Hi, What kind of damper and tires do have it? Do you have any more update about it? Ready with body? Are you satisfied?

Re: Sven's 4-TEC 2.0 Rally
 

Very nice I’m building one into a rally car also , I love the way this car handles which chassis do you like better the xv01 or the 4 tec.

Re: Sven's 4-TEC 2.0 Rally
 

He's posted pics of the shocks, with part numbers and all... Tyres look to be Tamiya Rally Blocks.

How have the shocks held up so far. There's a few bad reviews on them...

Re: Sven's 4-TEC 2.0 Rally
 

Holds up very good! Like most Traxxas vehicles its very 'bash-able'. I have been rallying and bashing pretty hard and still holds up fine.

A lot stronger than my XV-01 which i always feel i have to be careful with. The XV-01 is more scale like, but for more out of scale superfast fun/bashing the 4tec is definitely better!


The shocks are pretty good now, upgraded them with x-rings instead of the stock o-rings (which leaked pretty bad).

I hate to sound like a broken record, but...

If you have time, could you check if a wheel with an inner diameter of 1.72" or 43.7mm would clear the suspension components?

I am thinking these 1.9" x 21mm wide wheels would make for a cool retro rally build:

With these tires (Height: 93mm or 3.6 inch - Width: 24mm or 0.94 inch):

I know the tires will be tall, but I will just need to find a body that I can hack the fender openings up a bit...
