Before purchasing my Bomber, I made my wife watch more vids like this than she cared for... she wanted to die... I still love watching these rigs work. The IFS looks great... nice video.

I am trying to get some SSD wheels coming and initially I will just swap the stock tires over. I noticed that you have stock Baja's, the K35 Baja's and the Proline Flat Iron's. I'm sure you have others as well. I am leaning heavily towards slow technical crawling. I have a lot of Granite and Limestone near me and I travel frequently for work to Southern Utah which is amazing sandstone for days. Which of your tires do you prefer for crawling?

I also noticed that your Flat Irons don't look as soft (air'd down) as the stock Baja's and foams. Thoughts?

 

[bilinvic]

I hear ya...I enjoy watching close-up views of the tires and suspension working.

I've read the stock Axial KR2 tires are difficult to mount on beadlocks because the beads are made for glue-on rims. The Axial R35 versions are apparently made with regular beads and no internal stiffening ribs. I've never run the stock KR2 tires that come with the Bomber, so I cannot comment on their performance. Although I do have the P-L KR2 tires, I still haven't tried them out yet, I suspect they will be great on the dry rocks. You are correct, after reviewing my video, the Flat Iron XL tires need softer foams. I'm pretty sure they are CI DD 6.0, I'll order some CI DD 5.5 foams and see how they feel because I really like these tires. I also love the Pit Bull XOR tires, but they are very wide and shorter. I may consider a pair of VooDoo KLR 2.2 tires if they ever get released!

It appears VP Yeti knuckles and Axial Universals don;t play well together! Lot's of metal shavings.:x

WoW !
i have ran axial uni's in my yeti with Vp hubs they did rub a little
& i did have to clearance the insides some but not that much !
watch the hub/bearing slop i normally have to shim all hubs up one or two shims !

now we know "why" i am running - yes - STRC hubs & C's,
they will take just about any drive shaft with out doing anything to them.

we must watch for how much front end travel your getting !
now that the shock tower is getting taller & were putting longer shocks on this front end - trying to get the most travel & the tallest ground clearance,
doing so puts everything at its most extreme drive angels at both ends of the drive line.

if your using a drive line with a dog bones on one end - watch when you cycle the suspension & make sure the suspension stops when the drive shaft hits the drive cup & go's no further !
if it dose - your going to brake that drive cup in half when the rig bottoms out hard !

we can only run the amount of travel in the front end as that drive cup will let us ! - pireod - thats the limiting factor in the yeti front end !

no matter how tall of shocks or tower we use - it comes down to the drive system bottoming out on the drive cups or cvd's binding at there limits !

Well said Jerry...you're advice is definitely appreciated. Where are you shimming the front axles, behind the 12mm hub?

Some forward lighting mounted up now; RC4WD Baja Designs Squadron LED pods. I used the existing interior mounting locations on the dash so they are safe and out of harm's way.

yes - back side of the hub !
with these from Ebay !!

Nice vid Bil. I like the hood pin decals too, nice touch. I'm really starting to love my Flat Iron XLs too. I don't even have them broken in yet and they just stick so well and I'm running Deuces Wilds, lol. I can sometimes hear them clawing with each tread if they're searching for traction on a climb, it's a cool sound.

 

[nfcrockett]

Bil, you and screamer are making it very hard to wait patiently on B1B #9! I happen to have a set of flat iron xl's as well that have just been collecting dust. I'm interested to see how well they perform for me. Keep the info, pics and vids coming. #DMGB1BBomberBrigade 8)

I just finished 1.25 hour test session......all I can say is HOLY F**K, this machine is amazing (Excuse my French!!!).

Just wanted to let you know, but when you posted this, it's what changed my mind going IFS on my bomber too.:lmao:"thumbsup"

Any updates?

 

[bilinvic]

I'm glad to part of this B1B virus 84yoda!!!

I was hoping to get out this last weekend for a big shakedown run, but unfortunately that plan didn't materialize.

I have put the SSD Rock Racer wheels and P-L BFG KR2 tires on the B1B for now to test them out. The other reason I want to use these wheels is because they utilize an SLW hub and I have Exile RC brass SLW hub weights that I wanted to use. Although the balance was almost perfect on the test day, I felt I needed just a touch more front end weight. I have spare RC Bros knuckle weight kits but they unfortunately won't work on Yeti knuckles and the next best thing is SLW hub weights. Right now I'm using Vanquish .600 hubs up front and have .450 SLW hubs on order from RPP...the front needs to be narrowed up a bit to mach the rear track width.

I also have another complete set of SSD Rock Racer wheels on order because they look so damn good...I need them on my other Bomber. The KR2 tires will go back to the other Bomber too, I have Crawler Innovations Double Deuce 5.5” Comp Cut Inner / Soft Outer foams coming in this same order from RPP for the P-L Flat Iron XL tires, the 6.0 DD foams that are in them now make the tires a little to firm for my liking.

Axial 14x54mm 3.85 lbs/in Medium Green springs are on their way too, I want to soften up the front shocks and see how they perform over a stiffer spring that's on them now (4.33 lbs/in - Yellow).

As mentioned above, I have some KBess Mfg limiting straps (blue) ordered that will hopefully will work out. I'm more concerned about the front because I don't want the front A-Arms maxxing out on full droop.

That's about it for now.

....and I forgot to mention, I have a pair of the new Incision VDI axles coming.

Ive seen beef patties and tss drum hub weights but haven't heard/seen this exile setup. Link?

Exile RC is in my neck of the woods in Canada...

Today is the day my B1B Bomber gets it's shakedown run...should be a about a 5 hour crawl/bounce if nothing let's me down!

I didn't receive my parts that I was expecting on Friday, so I will be running with my newest favourite tire, the Axial BFG Krawlers with Gearhead RC wheels.

 

[bilinvic]

Gotta wear my DMG shirt when I roll with the B1B Bomber!!!

Now you guys can place a face with the name too.

[powder4breakfast]

I'd like to make a shirt that says "I'm e-friends with bilinvic" to wear when I run my car. The back could say something like "it's a small crawler thing... you wouldn't understand".

Anyways, always nice to connect a human face to people.

 

[bilinvic]

...Now that's one of the funniest things I've heard in a while p4b...I even had to show my wife!

 

[bilinvic]

It turned out to be a 6 hour crawl session today. Let me start off with saying that I know I have some pretty awesome rigs in my collection that are dialed in for maximum crawling performance....but with that being said, the DMG B1B Bomber is definitely the best crawler I have in my arsenal of machines after today's mind-blowing performance.

I would like to think that I have some credibility to my name and know what I'm talking about....I don't want to throw around the "best crawler" expression around lightly, but this machine is out-of-this-world fantastic at crawling and bouncing, not to mention an incredible amount of fun.

I feel it's absolutely perfect and dialed in 100%, but with that being said, I'm always searching for more and want to get 105% performance and will continue tuning to get that extra bit more.

My buddy got lots of video today, hopefully that will be edited and published soon. In the meantime, I have some photos.

The only issue I experienced today was that I lost the screw for the steering linkage at the steering rack. I thought I killed the servo at first. A quick field fix and I was good to go. The B1B Bomber dished out some serious aggressiveness today and never once failed. Although, I am hearing a bit of gear crunching under heavy acceleration, I'm hoping it's just the spur because everything else is metal (the grinding sounds like plastic). I will rip everything apart and inspect all components to see if there's any unforeseen weaknesses.

I cannot wait to get this rig back out on the mountains.

Mr. DMG...take a bow good Sir, your B1B Bomber kit is worth every penny it cost me and is by far one of my favourite builds; thank you.

And by the way, these Axial R35 BFG Krawler tires killed it today....I LOVE them.
