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. |
Re: Building my dad a 5th dimension berg 1 Attachment(s) Attachment 377244 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 2 Attachment(s) 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 Attachment 377246 |
Re: Building my dad a 5th dimension berg 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! #compcrawlingisnotdead |
Re: Building my dad a 5th dimension berg 2 Attachment(s) 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. Attachment 377251 For those wondering the weight. That includes the shock sliders, 4 3mm spacers, and 8 steel hollow balls Attachment 377252 |
Re: Building my dad a 5th dimension berg 1 Attachment(s) 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. Attachment 377305 |
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 3 Attachment(s) 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. Attachment 377308 |

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? |
