I am finally happy with how my savage has turned out. Its taken many months, more money than I'd like to admit... And the classic, blood, sweat and tears!

It started its days as a savage xl 5.9 with an LRP 32 spec.4 as its lungs. It was a great setup and I enjoyed it for a while. I found a photo of it from a while back with no shell. The only upgrades I did to it at this point was big bore shocks, the engine (of course), and sway bars.

Being very into electronics I found flux trucks more and more appealing, once I could finally afford to convert it the fun began!!
Here's a photo of what the truck looked like after the dodgy conversion, keeping the xl chassis and engine mount. It wasn't pretty but it worked. The esc mount was just a bent sheet of aluminium which always threatened to break, and the battery boxes were really badly mounted as there was no mounting holes for it on the standard xl chassis. They weren't even in line!!

Now comes the proper build! Once I was fed up with the crappy build I decided to do it properly, and here is where I recommend anyone else starts if they want to do the same conversion. Its not cheap but it'll be done right from the start!

Image Breakdowns

Carrier and Upper Arms

Before the chassis arrived from alza racing, I had installed the adjustable upper arms on the rear as well as an aluminium hub carrier. This eliminated the turnbuckles on the rear which have broken on me several times. You can see the sway bars in this image too!

Center Diff Transmission
When the center diff tranny arrived I took it apart to replace the grease that was in the diff, unfortunately the diff case in mine was terrible, there were cracks and broken parts in it. Luckily I had many spare housing from my previous savage's (RIP my very first savage that became a parts bin). Apart from this, the transmission makes a conversion so easy!! I converted my 3 speed transmission to a single speed and that took some time and many hours of research for the parts I needed. For around $60USD you can get a whole new transmission with a center diff!! Amazing! I have found it also takes some stress out of the front and rear diffs too which is a plus. From memory I put 800k diff oil in the center diff.

Alza Racing Chassis
I was so pumped when the chassis arrived from Alza racing! Even for the cheapest ones they offer, the build and quality of these are insane and well worth the cost imho! I also had a little email chat with the owner, he is a very nice dude! For some info on his side, he has to drive to Vienna from Benedikt in Slovenia just to ship to Australia!! What a legend to have the dedication to do this! Cheers mate!

Also seen in this, I got some aluminium mounting brackets to replace the plastic ones that I stripped. You can also see the new tranny, fits perfect, which makes sense as its the same housing... :p
As a bonus, I finally had a chassis with mounting holes for the battery boxes! What a win! I was so pleased with this as my crappy setup before made my truck very unbalanced.

Custom ESC Mount
As mentioned before, I made a custom mount for the esc because forgot to order the one that alza racing supplies, still happy with the way mine turned out! The alza racing one is so cheap, I'd recommend just buying it with the chassis instead of trying to make you own.

I mounted it using 4xM3 nuts and bolts. I mounted it in the same location that the alza racing one would mount to. Its simply just a cut-to-size piece of 50mmx50mm aluminium angle. The ESC itself it mounted using very strong double sided tape and a zip tie just in case.

The End Result
I have sadly maxed the amount of images I can attach, but I shall post in the comments!!

Not seen in these images was the installation of the motor mount plate and the brackets, but it was super easy as it was a direct fit! Overall, the upgrade to flux wasn't hard, so long as you have the right parts and you take your time!

If you have any questions don't hesitate to ask! I will reply as soon as I can and as well as I can!

Looks like a great setup @Biddie_fiddler! Get some video of it running at the track and post it up!
Recently bought the DJI osmo mobile 2 gimbal, its got a tripod mount and has the object tracking feature like in their drones, keen to see if I can use that to track the truck at the jumps
 
Looks great, i have just installed the Alza center diff conversion on mine, have yet to try it.

I didnt know about the one you have used, that would have been a cheaper option.
