TLDR, w/ Build details and descriptions
Almost all parts are in for the start of this project.

  • Used the Best stuff.. Simple Green
• Pic03: Chassis Bottom before
• Pic04: Chassis Bottom after
  • Tools Used: 5" Oscillating palm sander, and hard foam Block sander.
  • Started with grit 280> 400> 800> Finished block sanding with 1000.

  • About the closest I could find that approx. relates to the basic outdoor bashing scenarios.
  • I will start with F/C/R to 12.5/15/15 due to slightly larger/wider tires with more bite.

So you're building a Nomad DB-8.?

 

[JLspeeddragon]

I plan on upgrading the composite 46 Center Diff to their Steel version when money / time becomes available to me.. Already dropped a couple hundred into the start of this build so need to spread out the money in / out flow..

So you're building a Nomad DB-8.?

Nope.. I'm going to still run an E buggy body on it, just doing an overhaul on it from my previous racing days setup to Basher style ..
There were many restrictions for off road race legal from where I was racing out in the pacific northwest coast area..
Since I've moved back home area, no race tracks in the area worth driving 2 1/2 hours+ away.. So gonna make it a basher with NO restrictions .
Basically it will be an Associated 1/8 Buggy version of the Arrma Typhon 6S.

Ok, carry on. We are running the Max 8 4272 on 6s with our Nomads and it has been excellent.

F/C/R diffs rebuilt and installed into the new HD gear boxes.
Gears are
F 44/13
C 46T going to start with a 16 pinion
R 44/13
It's going to have some serious spunk, even at 4S!
I went with 20/20/12.5 for the fluids for now.
Next will be breaking down / rebuilding the F/R assemblies to the setup I have linked in the OP. I may swap it to Spencer Rivkins instead.
Pic is a bit of a mess lol... Never been to OCD....

That's awesome! The only difficult part for me was tracking down the wheels and tires for mine. I wanted to keep the same diameter as race tires, just slightly wider. The selection for 2.8" wheels with 17mm hex and low profile wider off road tires is scarce.

I did my damnedest trying to track down some proline F-11 2.8"s, but only choices are outside U.S. with stupid high shipping. So I had to go with the 2.8 6x30 raid wheels instead.

I already knew I'm going to have to run extended hexs and or offset wheels for the tight turn radius this bug has...
Let me know when you decide to tackle it

Update:
Spent the day yesterday building the front and rear assemblies.
Today working on the tires and wheels getting them prepped and ready for gluing. Tires are taped on the inside using gorilla tape.
Vent holes are leather punched out.
Wheels and tires glue bead area have been sanded.
Getting ready to rub them down with alcohol and start the gluing process. Wish me luck!

Update:
Tires are glued up and setting for the day to fully cure.
Front assembly installed onto the chassis.
Was in process of getting ready to install Rear assembly and this happens!!!

Damn threads broke off!
Now I have to wait till next Tuesday sometime for the new ones to come in! GRRRR!!!

 

[JLspeeddragon]

The Pro-line 6x30 hex adapters came in...
This buggy is gonna be bonkers!
I may put the original stock 17mm hex nuts back on (0 offset). Currently with the+2's...

Updated details and pictures from yesterdays work on the Buggy.
I had pre-ordered complete set of Avid bearings for the Kraton EXB and the RC8B3.2e buggy for this project build.
Installed the Arrma Kraton EXB rear hubs.
Had to swap pivot balls from a spare set of Arrma turnbuckles into the RC8B3.2e turnbuckles to fit into the rear hub. Almost perfect fit! slight tension but it will work its way out.
Rear Hub minor mods:
RC8B3.2e hinge pins are 3.5mm, Arrma 4mm. I used a piece of .5 nylon tubing to shim to fill the void and remove any play. Held in place by the 3.5 adjustment spacers.
Will have to slightly sand off top inner of the hub to allow the 2.8 wheels to fit without rubbing.
Installed the 2nd Arrma Kraton EXB front steering hub.
Used all the Kraton EXB parts on this process.
Replaced many of the Flat & Button head screws with Socket heads where I could apply them.

Today's Progress:
Rear Assembly grease sealed and installed on the Chassis.
My Spektrum 6S V5 ESC came in while working on the buggy.
Adjusted front steering some (still needs some tuning)
Got the Electronics installed and bound to my Flysky G7P.
Grease sealed around the receiver box.
Everything I can I grease seal to help with water resistance / proofing.
One of the motor fans does not work so will have to deal with that Saturday.
Went OCD mode on the wiring.
If you have followed my Talion build, then you will notice the wire clips.. These things are amazing help!
I have illustrated where I have placed them all to help keep the wires organized and out of harms way.

Saturday's plan..
Hopefully the Typhon driveshafts will be in for the install.
Shocks rebuild and install.
Some minor grinding on the rear hubs to allow the 2.8's to fit without rubbing.
Balancing the tires.
