Building my dad a 5th dimension berg
 

I haven’t done one of these for awhile, so let’s consider this a practice build thread. I’ll be posting my xr, superlite berg, and shafty soon. My dad has expressed interest in wanting to compete so after gathering parts for the last couple months it’s time to start building his new truck. The plan is for a reliable truck that he can learn with and grow into so a berg made sense. Full parts breakdown below.

Chassis:
Carbon 5th dimension dominator
Narrow skid
TSK’s shock sliders

Axles:
Berg cases
CKRC Droid tubes
Dlux missing link lockers front
Rcbros locker rear
Xr shafts front
creeperbob ti shafts rear
Drilled gears with Mann 2nds and ckrc 3rds
Mfd link mounts
Dlux knuckles
Dlux loaded dice weights

Suspension:
Dravtech comp shocks
Traxxas three hole pistons
Dravtech soft springs
Full ti links (3/16 lower and 1/8 upper)

Electronics:
Hitec 7950
Brood motors
Brood Pure Energy 500mah 3s lipos
Castle bec
2 Br minis
Futaba 4pk

Tires and wheels:
Ottsix voodoo gold pins (narrowed)
Crawler Innovations 6.0 foams (narrow inner, narrowed medium/firm outers)
Dlux D-cut loaded dice wheels

I think that covers everything. Plan is to have it done in the next week or so as I plan on giving it to him for Christmas.

Got the tubes all put together, cases shaved, motor plates machined, and link mounts set. Still need to build a servo mount but need to check motor to tube clearance first. Waiting on some bearings which should arrive tomorrow to finish putting them together.

Re: Building my dad a 5th dimension berg
 

Whoa, look who is back!

Re: Building my dad a 5th dimension berg
 

While I’m waiting for bearings to finish up the axles, I decided to put together shocks. They are limited both internally and externally with 3mm aluminum spacers.

Attachment 377245

I also got the Ottsix tires narrowed and glued to the Dlux carbon loaded dice wheels. I ended up taking 2 rows of pins out from the center. I use Crawler Innocations foams in all my tires, so it only makes sense for me to use the same here. I chose the 6.0 double duece with narrowed inners. I also narrow my outer foams to match the width of the tires, mediums for the front, firm for the rear, with no tuning rings

Oh hell yea, your dad is a cool cat so I look forward to losing to him even on his first day at the wheel. :lmao:

Re: Building my dad a 5th dimension berg
 

Awesome!

Re: Building my dad a 5th dimension berg
 

For the chassis I went with a 5th dimension dominator. For people that know, this is the exact chassis on my xr10. I recently switched over to a blue carbon dominator so had this one ready to go. I swapped all my blue hardware for raw aluminum hardware. Since the upper and lower links are mounted in double sheet I used aluminum hardware there aswell.

For those wondering the weight. That includes the shock sliders, 4 3mm spacers, and 8 steel hollow balls

Re: Building my dad a 5th dimension berg
 

I drilled out the gears today, but I think they will probably end up as spares since I ordered some rc4wd berg gears earlier today. I ended up finding some mann 2nd gears and ckrc 3rds so it should be plenty strong. I did end up clearancing the front universals slightly as well as remembered I had some ti straight axles from creeperbob. So I decided to throw those in the rear with a rcbros locker instead. I do wish the rear shafts were 4mm threads like the front, but this will have to do.

Re: Building my dad a 5th dimension berg
 

Are those rear shafts 6mm at the pin? If so I have some brand new 12mm hexes I'd gladly mail out.

Re: Building my dad a 5th dimension berg
 

Yeah. I’m gonna try drilling out some axial hexes in a bit. If they don’t work out I’ll message you.

Re: Building my dad a 5th dimension berg
 

Groovy, just remember to hold your tongue juuuuust right and the hole will be straight.

Re: Building my dad a 5th dimension berg
 

We just need more people posting builds...

Re: Building my dad a 5th dimension berg
 

Then I'm out 'cause I don't build shit. I buy all my rigs used and run them as/is. :roll:

Re: Building my dad a 5th dimension berg
 

You probably built 2 trucks while typing that sentence :shock:

Re: Building my dad a 5th dimension berg
 

So I got the axles mostly buttoned up.

Attachment 377306

Rear axle ended up being a touch under 13 ounces with the motor. Not the lightest by any means but pretty good considering it’s all metal with motors that are relatively heavy. Speaking of motors, decided to go with some 30t big wire 540s with turned down cans. After running lots of different shorter and smaller diameter motors I feel the weight loss isn’t worth the low end power and control.

Attachment 377307

For the front axle using a 13t pinion I was able to fit the servo between the tube and motor without having to grind the tube. I still need to build a servo mount but it shouldn’t be too bad to get done. I am still trying to decide between 3mm carbon or 1/8 6061, I guess that’s a problem for tomorrow though. Weight ended up being about 24.5 oz with the servo, motor, and empty loaded dice (they are going to need to be flipped around to fit with the current hub). I figure it should be about 26 oz with steering links and a servo plate. I also still have the ability to add another 4 ounces per side in tungsten when the time comes.

Re: Building my dad a 5th dimension berg
 

I wish, I'm driving so I have to settle for working out design details in my head. Tomorrow...errrr today I build. :lol:



Axles look good, been a while since I've seen a set of those tubes.

Re: Building my dad a 5th dimension berg
 

Great build thread Nabil! It is wonderful to be a part of a hobby where families can participate together. I'm certain your dad is going to enjoy the rig and time with you. The youth of today need to see all the different ways a family can move in healthy relationships. "thumbsup"


If I, or Crawler Innovations can help in anyway. Please contact me.


Have you had an opportunity to test out the cubed gate markers yet?

Re: Building my dad a 5th dimension berg
 

Thanks Eddie, of course I will let you know if I need anything. I haven’t actually had a chance to drive the last couple weeks, but I did find a bunch of vanquish weights for the cubes. We’re havimg a comp this Sunday so I will probably bring them with and see what people think.

Re: Building my dad a 5th dimension berg
 

great step by step build project.
thanks

congrats for this great rig

Re: Building my dad a 5th dimension berg
 

Thanks! Hopefully my dad likes it

Re: Building my dad a 5th dimension berg
 

I didn’t get much done today, but did finish up the front axle. I started by making a servo mount out of 3mm carbon. It is held to the axle with 3 screws and red loctite.

Attachment 377316

Attachment 377315

Then I fired up the dremel again and made a battery tray for behind the motor. It will it will use a piece of inner tube for a strap aswell as get covered in velcro.

Attachment 377317

I also added steering stops to the axles using a 3mm spacer and button head screw which can be seen in the previous pictures. I figured out that a straight xr10 tie rod is an almost perfect fit with the Dlux knuckles and his proper ackerman arms. I put a slight bend at both ends to bring the tie rod closer to the gearbox and called it good.

Attachment 377318

This might be the last update for a couple days. I have a comp this weekend and I need to make some tires and do some maintanence to my personal trucks.

Re: Building my dad a 5th dimension berg
 

Looking good Nabil! "thumbsup"

Re: Building my dad a 5th dimension berg
 

Comp? Wheres this comp?

Re: Building my dad a 5th dimension berg
 

I totally agree with this. The set of Team motors i had Eddie at Brood build me are in standard size cans (i think?). I think smooth start up is the most important thing when crawling and bigger can are just better. Big cans and skewed arms!!"thumbsup"

Oh, by the way...Have you tried the single bend links? If so, how are you liking them?

Re: Building my dad a 5th dimension berg
 

Richmond this Sunday, Folsom next Sunday

I’ve been running a really shallow bend (like less than 1inch vertical height difference) rear lower for a long time. My xr needs a double bend lower link though since the shocks and links are in the same hole. I’m going single bend front and rear on both this truck and my superlite truck which I still need to build.

Re: Building my dad a 5th dimension berg
 

The brass weight holders are actually supposed to go on the other
way, but you can probably get away with running them that way...

Re: Building my dad a 5th dimension berg
 

With the hub that’s on it they will definitely need to be flipped (see post 16 :flipoff:)

To add some tech for people who may not know. If you look closely you can see I flipped the knuckles upside down from how Dlux says to put them together so I have more clearance for the loaded dice weight at the bottom. I just learned this trick recently, and while it only works on non 8 deg, it allows for the button head screws to be at the bottom, which fit into the loaded dice weight better

Re: Building my dad a 5th dimension berg
 

I see it now said the blind man "thumbsup"

Re: Building my dad a 5th dimension berg
 

I think stubs thought that one up. I set up greengo that way, makes it easier to deal with the brass dice for damned sure. Delrin are no big deal since Erik cuts those correctly. :lol:

Re: Building my dad a 5th dimension berg
 

I still really dig the older style Berg cases cleaned up and shaved down....I’ve got an old set I’ve been eyeballin again and a set of RCBros tubes your probably missing too....it’s good to see you back

Re: Building my dad a 5th dimension berg
 

Thanks Brandon. I still have another set here, but I wanted to use these. I don’t know why but I’ve always liked these tubes.

Re: Building my dad a 5th dimension berg
 

Had some time today to work on it today. Since it’s pretty much impossible to find vanquish ti links anymore I kinda guessed on some lower link length measurements and sent the info to hardcore rc over on facebook. I ended up having to put a bit more bend in the links then I wanted, especially the rears, but I think it should be fine for my dad. The extra clearance might actually help him while he is learning how to pick his lines. I made the uppers myself using 1/8 ti, a hand drill, and a 6-32 die.

I’m not entirely happy with how the rear axle is sitting. I will probably play with the lower link mounts on the axle to get it to sit more to my liking.

Incase anyone was wondering about the weight, it is currently sitting at 3.8ish pounds. Only things missing are 2 speed controllers, rx, bec, and battery. I still have steel hardware everywhere but the chassis aswell as a couple of other places to cut weight if I wanted. The loaded dice are still empty, so that’s up to 8 ounces of tungsten that I could potentially add to the knuckles aswell.

Attachment 377497

Re: Building my dad a 5th dimension berg
 

I’m sure some people did it by accident before I did it. I’m just too lazy to grind that much.

Looks good man. You could always throw a Dlux “replacement” case on the rear to suck the motor up against the axle tube. I think they are pretty cheap for just the gear case? I love being able to drop the motor without sacrificing ground clearance.

Re: Building my dad a 5th dimension berg
 

I’ve thought about it, my ocd wouldn’t let me do just the rear though. Depending how much he enjoys it and uses it will dictate what I actually do but either way it will probably wait until I have to rebuild it. I did end up rotating the lower link mounts and lowering the motor from the pictures posted. It’s definitely let better now, I think it should be fine.

Re: Building my dad a 5th dimension berg
 

Hey Nabil remember this video? This is my all time favorite berg video.
https://youtu.be/8bRldkeCWWc

Re: Building my dad a 5th dimension berg
 

Yes!! I’ve been looking for that video for awhile now. Those axles are currently sitting on my desk right now. I’ve been considering building that truck back up again. Thanks Matt!!

Re: Building my dad a 5th dimension berg
 

Nice, glad I could help lol. Axles look very similar to the axles on your Dad's rig.
Don Hughes has a chump RT chassis it's Doncrawla's old chassis it had xr axles. If your looking for one.
