So the build Commences
The points I wanted to address:

The Front and Rear Diffs
Method of mounting my centre diff and motor
Improve bearing wear on the wheel hubs
Utilisation of Mechanical Brakes with 12s Air ESC from Castle



Front & Rear Diffs
Objectives:
-Remove the use of the 10x16x5mm bearing on the stock flux alloy cup (this prematurely wears)
- Replace the weak internal gears of a flux with stronger gears.
-Find a cup that accepts the BulletProof Savage Flux Ring Gear
- Find appropriate diff axles to use with my LST2 Shafts.

I found that a Vorza Diff is better than the savage diff in every way APART from the Ring Gear, and it met all my criteria!
The Vorza uses the HOT BODIES HARDENED STEEL INTERNALS

I took plenty of pics to compare...VORZA VS SAVAGE DIFFS (all vorza parts are on the left and savage on the right of the pics)

Diff Mess
Image

Firstly i will say that the vorza diff cup, although plastic... is extremely rigid, and due to the design, actually has more material. So i have no problems using a plastic cup knowing it is this tough. You will notice this in the pics.

Notice in the pic below, the steel cap which allows the vorza cup to use an 8x16x5mm bearing. Also notice the grub screw. This allows the use of a larger pin to hold the sun gears in place, dispersing the force over a larger surface area much better. (i snapped these pins often with the shorter savage pins. Pics will show this further down.

ImageImageImage

Spider gears are ever so slightly thicker. Maybe not noticeable on camera, but in person you can notice a slight difference. Also notice the longer axle pin! Also the washers that go behind the spider gears are twice as thick as the savage ones and are not flexible.

Image

Sun gears... slight difference again.. .vorza on left... the gears are ever so slightly more robust than the savage?

Image
Image

AXLES
Obviously there is going to be a differnce... but i believe the strength of both seems quite equal...There is an obvious difference in length in the picture below... But I am only making this change because im running different drive shafts. You can still use the Stock SHD Flux axles.

Image

RING GEARS
obviously there is going to be a huge difference... but more importantly, yes the BP gear fits tightly and all screw holes line up perfectly with the vorza cup

Image
Image

Mounting Centre Diff and Motor

Although my previous way of mounting my diff and motor was very tough, I wanted to try something new, that allowed an easier mesh of my gears. I was skeptical of using a truggy/buggy style of mounting everything as I thought it would be weak for the motor to be hanging. But I have see many launch their RCs to the sky and never had problems with the motor pulling away.

But I took extra precautions to prevent this ever happening.

Dejan at Alza Racing Created my Diff mount. It is able to utilize mech brakes and he created a very solid mount.
As you can see? it has 3 points of attaching to my chassis rather than the usual 2. This should give it a little more strength and prevent any movement.

Image

A spacer for my motor had to be created to pull the motor away from the mount to allow clearance for my Mech brake setup. I have used Titanium screws to hold the mount to the motor, instead of just bolting the mount to the motor with 2 screws. This uses 4, which is definitely a lot tougher and should deal with any accidents at speed.

Image

This is the spacer mounted to the motor

Image

And everything mounted to the diff mount including brake assembly

Improving bearing wear at the wheel hubs

This was one custom idea I couldnt have completed without the help of lincpimp on RCMonster. He did all the initial mock up work to see whether or not this was possible?

The LST2 Hub Conversion idea came around for multiple reasons

-The use of CVDs.
-The potential to install 3 bearings in the hub.
-A more Robust Hub Design.
-Increase in width without having to use XL Extenders.
-Ability to use the stock savage A Arm
-Use a proper hex rather than the savage hexs.
-And most importantly... TO DO SOMETHING DIFFERENT.


How it all started with Linc mocking things up.

Image

As you can see in the pic below. The drive shaft although the same thickness as a SHD Savage shaft, it a little longer. Meaning the lower bulk pin wouldnt line up.

Image

So he made some braces that replaced the stock lower hinge braces and pushed the pins to the outside of the bulkhead. This resulted in a success. The drive shaft sat in the ?axle cup, and the arm was held in place perfectly.

Image

This is when I had to find a cup that would accept the LST2 shaft. The vorza cup worked perfectly.

Image

Thanks to 78.8 on MSUK he managed to send me over his extra LST2 parts for mocking up my own bits.

Here is a picture of a stock savage arm and hub next to the new setup. Notice the gain in width.

Image

It was time to come up with a better solution that would be extra strong... Who do I call? Not the ghost busters... But Dejan from Alza racing once again.
(This guy is awesome we spoke for weeks about my parts and we had over 400 emails go back and fourth during that time! Without him, this project would never have gotten to where it is now!

THANK YOU DEJAN!!!

So what did he create for me? Well it started like this

Image

And the final result!!!

Image
Image
Image

His work is unbelievable! Great Prices, Great Communication! Just awesome to deal with!

The upper arms required spacer either side of the stock savage upper arm? these were made up by dejan too

Image

So everything worked and I thought it was time to spend some monies once again as I wasnt satisfied with the stock plastic bits
After a month of waiting something came through my door...

Image

And how they compare to the best savage parts available? Definitely more robust. Yes heavier, but this is going to be a solid build

Image
Image

Something I forgot to mention... ?In order to get the LST2 hubs to work the stock savage arms. A small part of the hub needs to be filed down.
It is nothing difficult, and doesnt take long.

Image

A picture showing how the 3 bearing mod will work inside the hub.

Image

The third central bearing, does not sit tight and there is movement as this space within the hub wasnt designed for a bearing. But using just one thin piece of electrical tape around the outside of the bearing, allows it to sit snug in the hub.
A spacer is required to be made up. This will allow the bearing to sit as close to the larger, weaker 22mm bearing.

Image
?
Image

This should hopefully result in a tougher, more reliable better handling savage.[/align]

Utilisation of Mechanical Brakes with 12s Air ESC from Castle

For my build, I wanted to run at least 9s, just because I knew castles 8s ESC MMXL was becoming available. I know this isnt a correct way of choosing your power, but this was just one preference that HAD to work.
I decided to go with the top of line Air ESC Ice HV 160amp 12s ESC capable

Image

I then realised, WOAH this thing is huge? where am I going to mount this beast!

So I send Dejan another email? And he quickly hooks me up with this awesome plate!

You have to love the free engraving job

Image

All mounted

Image

Extra pictures including my Integy RX Box and BEC plate

Image
Image




So onto the rest of the stuff?.

Cage


The cage I had made previously, was mounted directly to my skid plates. So any force incurred would transfer force to the skids rather than anything solid. I had a brace I made that held everything in position. But they were looking a little worse for wear? So I had ?Dejan make me some 5mm bits

Image

Wheels , Tyres & Extended Hexs

I loved my SPI rims from Rick! He did a great job, and im sure they were the reason my savage handled so well!
But I did notice that even on 6s and with my grippy badland tyres? that they couldnt really put the power down. Plus after the battering I gave my spis, they were looking a little worse for wear haha

Image

after a little polish

Image

BUT THIS WAS JUST NOT GOOD ENOUGH!

This was a new ultimate build and I needed something new.
I decided to go with some baja wheels and tyres! After IBO on MSUK gave me a cracking deal I went for it.

Some Proline Baja Bow Ties on Desperado rims. I went for these instead of the popular hostile rims because the side wall grip is less than the hostiles allowing me to slide and drift rather than flip over when turning.
Plus as my savage is lighter than a baja, the wear wont be as bad.

I used two wraps of Gorilla Tape to belt the tyres and the foams as I wanted minimal ballooning at high speeds.

 Image

After I decided on this combo, I knew I would lose some off the offset I had with my full offset SPI rims, so after I found the extended hexs below, I was a little worried about them holding up. But Brian on RCMonster reassured me that these were very tough on his 20lbs Extended LST2 conversion, even whilst jumping.

 Image

All taped up
Image

These Hexs are 23mm hexs... And my Baja rims are 24mm hexs...
So with some advice, I bought some Alloy Tape and wrapped the hex until it fitted snug in the baja rim. Many have done this In the past with success.

BLING

I bought some other random things to give a bit of bling to the build

Some Alloy Shock towers? I know people hate them, and SO DO I but only if you are using a body to mount to your towers. As my cage doesnt allow any impacts to affect the towers, they wont bend or damage my bulks. So I thought why not.
Image

Alloy Shock Caps
Image

Also decided on some Mud Guards to protect my hubs, shafts etc from stones and other things getting caught up
Image

I know it is silly, but decided to cover them in carbon film
Image


More Bling ... Decided on an integy RX Box from a mini slash/revo to house my receiver etc
I also required a BEC as the Air ESC doesnt have an internal one

TVPS

After all this spending I realised my existing TVPs wouldnt be enough. I needed something new.
Chris at GCM is another legend. He helped me out a lot with getting me some custom TVPs! I loved his existing Desertboy-17 TVPs so much, I knew I wanted them again! But with a few little changes.

You can see how they are longer than the XL and stock plates

Image

and how my new custom plates looked  - They had a lot of meat on them compared, but this was because I had a lot more to mount within my tvps, so needed the mounting options.
Image

In order to prevent my TVPs getting ripped up once again from stones etc. I am making a 1mm thick lexan shield which will just bolt to the rear of the TVPs.
Image

How bad it did get...
Image





NOW TO COMPLETE THE BUILD  IT WAS TIME FOR ANODISING

Mark at UBER RC in the UK took on the job of anodizing my Alloy And I loved the finish they came back in. It wasnt what I was expecting... As I was expecting something very bright... But in the end, it came back a matt finish. WHAT A RESULT I loved it! No one would have this kind of finish! So I was very happy!

BEFORE
Image

After

Image

Image


So it all started with putting the front and rear bulks etc together
Image  

With everything assembled ... Loads of pics...
Image

Image  


Notice the carbon lower arms from Vantage racing? These were beautiful? but decided to go with stock as they allowed easier fitment of the HPI Sway Bars.

Starting to line up and install the centre diff and motor?

MORE PICTURES OF IT COMING TOGETHER!

Image

Image

Image

Image

Image

Image


I decided on running 8 Shocks on my savage...
This was necessary in order to maintain decent handling...

The red hellfire spings with preloaders is very stiff to hold the weight of the savage at a decent ride height... But it also meant that the damping was non existant. Im running 35wt oil in my Plastic BB and 25wt in my alloy BB... the additional alloy BB just there for damping purposes work very very well!

Built using Kraken RX Titanium Shafts

[align=center]FINISHED WITH CAGE AND INITIAL TEST VIDEOS

Image

Image

Image

Image

Image

Image

Image

Image






This is the first EVER video.
I wanted to make sure that, if it did explode... I would have caught it on camera
Mind the camera "women"...haha

http://www.youtube.com/watch?v=MO-gqU4mkPI

The video only had maximum half throttle, and this was a soft initial test run before pushing it...

What i found out...

Brakes required serious adjusting... not enough bite.

And what i thought was my pinion gear that shreded, was actually just the gear mesh...
As i was using washers to hold the motor to the mount, this was causing the problems... There is no longer any movement :)

This has all been fixed now, so watch out for the next video!
