Very good start! What's your intended purpose for the Bomber? Crawling, go-fast, or both?

I'd suggest the following for a dual-purpose Bomber.
ESC: Castle Mamba X
Motor: Tekin ROC412 3100kV. For faster speeds you can go with the Holmes Puller Pro 3500kv.

I intend to make it as fast as possible & handle as good as it can then maybe convert to an IFS front if it does not perform with the stock bomber front axle / diff setup

I am not building a scale model version to look pretty I will be more focusing on weight reduction etc

I am pretty set on the HH Puller Pro 3500K already after doing a bit of research

This was the very beginning of it, found a brand new stock cage & some brand new Wraith Spawn rims & tires
Certainly nothing exciting but it had to start somewhere

If you want fast the Puller Pro 3500kv is great. You'll love that motor.

A little bit more progress, building it from the ground up means all the little bits n pieces need to be sourced so I am waiting on parts to arrive still before I can continue further

Got a bit of a mock up pretty well done, CI foams & new R35 BFG tyres fitted

I like the RC 4WD steering link set in black too

Fitting stainless screws all over the lower steering & suspension areas as I live near the beach but I think it also looks cool

Long way to go but its getting there

Watch out for your rear axle truss smashing the snot out of your sway bar & bending it with it that way round.

Yeah I actually got a set of 4 brand new Axial Icon shocks shafts from the 90mm long shocks, the stock shafts are 59.5mm & the 90mm shock shafts are 53.5mm long so it shortened the extended length down 6mm, after fitting the "custom" shorter shocks I noticed the lack of clearance at the sway bar so I have fitted it back the other way now

I like the murdered out look!

I think you're going to want to upgrade tires and wheels at some point. The Axial tires suck IMHO.

And if you beat your truck you will kill the Axial shocks.

Are you talking about both the Axial kit R35 BFG & the Ripsaw tires? I have both
Hoping the Axial Method rims hold up ok but are they known to have issues?

Might have to upgrade the shocks later on then if they self destruct

I am aiming to make it as light as possible & you might even notice I have removed the fake plastic reservoir crap & other bits n pieces that are not needed

There seems to be a huge "scale look" following in the Axial scene where people just pile on a heap of parts for looks & while it does look pretty & probably doesnt really matter on a crawler it goes against everything that makes just about anything with wheels fast.....weight reduction!

All of mine & my sons RC cars will be anti "scale look" so unfortunately they might be as nice to look at to some people, performance outweighs looks for me so I will be doing quite a bit of weight reduction here & there wherever possible

Weight reduction is cool but don't forget the Bomber is front heavy with the battery and servo + the motor is mounted high up.

The "useless" scale bits can help with weight distribution.

Both. The Axial R35 compound is outdated, IMO. It was pretty good when it came out, but there are much better compounds out there these days. The Hyrax tires are a popular choice on the Bomber. They are awesome tires.

If you're going for light the stock wheels should work fine. I just personally hate mounting them.

The scale look is all the rage right now. Some people are all about it. Some people put performance first. And others, like me, like a little bit of both.

Yes thats the exact reason I am running the stock tires for now, want to keep overall weight & rolling weight to a minimum
I want to keep the size of the tire down to stock or even lower to keep the center of gravity low, I have the ripsaw tires for crawling if need be

I am aiming to see how fast I can make it go round a track for now even though it is meant to be a crawler I know, not looking for just straight line speed thats easy, challenge is to make it handle corners & just too

IFS conversion might be what I am looking for later on, by rights it should be faster than the Yeti Score TT possibly without a big body hanging off it

I have an Axial Score Trophy Truck kit as a chrissy present for my son so we can build it together, will be interesting to build that also & maybe get a few more ideas for the bomber too

Finally got a bit of time to get some more done, with the sway bar flipped back around the correct way I noticed where it hits the cage, looking at my sons RTR with the Axial sway bar fitted you can clearly see the sway bar to diff links are much shorter

I think its a bit overkill to use the huge 4mm thread links that Vanquish supply so I got hold of some 3mm x 25mm titanium turnbuckles , nice & lightweight, strong & very reasonably priced, 3 Racing part number 3RAC-TR325

Wasnt too hard to find some 3mm ends laying round, plenty spares from the lower shocks

I popped the Vanquish sway bar link steel balls into the stock Axial shock ends & it makes for a nice simple fix

I will get some more pics soon when some progress can be seen, waiting on some more goodies to arrive!!!

A pic of the modified links fitted, certainly no issues with the strength of them at all, this will work much better

Rear suspension fully compressed, now has clearance at the top of the links

Thought I would update some progress in here finally, hope nobody was holding their breathe waiting

Transmission conversion was completed via a Holmes TorqueMaster Extended Axial Transmission Outdrive set & a Billet Works Designs FOFF motor plate
Also have a billet transmission case waiting to build & a Hot Racing lightweight gear set on the way
