DravTech Sudu Zero by Force5
 

OK this is my first build thread, or should I call it a built thread.
The rig was finished just before worlds. with only 4 or 5 packs thru it. I was very impressed with a Fifth place finish at worlds.
I will try to get as much info in the thread and as quick as possible. Work has been impossible since returning from Logandale.

Here's the finished product.

So once I convinced Tobias to let go of one of his babies I started building components. First up was the shocks. I cut down the shafts to 35mm and re-threaded them.
The shock bodies were reduced by 10mm

Assembled using the Axial machined pistons and the lightest oil I had 20wt. RCBros spring retainer with pink Losi Mini-T front springs.

The lowers are 3/16 Aluminum 6061 .049 wall tube. Camera angle makes it look like different lengths. Fronts are just straight.

My eye to eye link measurements are as follows:
Front upper 62 mm

Re: DravTech Sudu Zero by Force5
 

Thanks ... It was HOT :twisted: HOT But still had fun.

Re: DravTech Sudu Zero by Force5
 

I received the Zero chassis and started acquiring the parts needed for the build and here's the list in the picture.

1.9 CI foams, soft & medium.
MRC diff gears and transmission.
Axial Wraith Universals and rear shafts.
MIP drive shafts.
Weights for the knuckles.
Axial thin hexes.
SLW .225 hubs
Shocks
Esc, Servo, Motor

I think I got off easy here. I had to purchase the foam, drive shafts and hubs.

"thumbsup"The axle shafts were the next item on the list. First I disassembled them and clearance them so there would be no binding. Reassembled and a quick shot of paint and ready for sizing.

OK here it is DISCLAIMER !!! Do your own measurements !!!!
If you use my measurements it's at your own risk!!

Here is what I came up with, please look at the picture for my reference points for front and rear shafts.
Front long 53mm, short 28.5mm
Rear long 82mm, short 58mm

I couldn't find my build notes to give you my measurements for the flats on the end of the shafts. I used a file and a vice to make them.

More later

Re: DravTech Sudu Zero by Force5
 

Where did the housings and servo mount come from ? I would like to do a wraith uni conversion...what else is needed other than the unis ? Do the c's, knuckles and lockouts come with the axles ?

Re: DravTech Sudu Zero by Force5
 

It's all from DravTech "thumbsup"

Re: DravTech Sudu Zero by Force5
 

Nice thread Dan!

You need to do more build threads..
Good pics, very informative, great parts, and good pics! ;)

Re: DravTech Sudu Zero by Force5
 

Thanks Troy "thumbsup"

Re: DravTech Sudu Zero by Force5
 

OK where was I , oh yeah the axles cut.
Next I assembled the front and rear axles.
Straight forward assembly, I need to shim the stock locker to get the correct ring and pinion pattern.

Once that was done I put it all together. "thumbsup"

Here's both ends and a side view.

It's looking like something now. :)

Re: DravTech Sudu Zero by Force5
 

It should be noted that the shimming is required because these axles were actually designed to be used with both Losi and Exceed ring and pinion setups, as well as the varied OD/UD options some are running. Tobias and I came to the conclusion that it would be easier to shim than run out of room.

BTW, the rig looks killer! Keep the details coming.

Re: DravTech Sudu Zero by Force5
 

Can you PLEASE provide a link to these parts?

Re: DravTech Sudu Zero by Force5
 

Congrats to your 5th place at Worlds!

Like Troy said, a really good and informative build thread!

Thanks a lot for posting up all this valueable information "thumbsup"

Re: DravTech Sudu Zero by Force5
 

About time I got back to this....
Time to put some rubber to the rocks!!
Tire building is new to me so I contacted PurpMart for set so 4.25" VooDoo/Ripsaw tires.
The wheel choice was obvious DravTech Cyclones with the printed inner supports.
The assembly was interesting!
<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
first install the outer face, then turn the tire inside out. Now remove the lip on the bead. I used my lexan scissors cut them off.

Now center the inner section on the bead with the face, and glue it on. Once the CA has cured turn the tire back over the center.

Install your foams then glue the inside bead to the center section.
You end up with this!
