motor mount FINALLY done. No fancy look since the only tools I have are a drill and a handsaw :D its made of a 4mm thick angled aluminum bar. I couldnt find a thicker alu bar, which would be much better, so had to stick with this one. The motor will definitely get some sort of additional support as it is 89mm long. I will use some scrap alu pieces that will be placed under the back part of the motor to support it. Image

the front and the rear braces are also finished and mounted in their places

Looks great
How is the twisting motion with just the centre upper support?

if you aren't
If you not braking something..... your not trying hard enough!

yes I will make an upper deck between the bulkheads that will serve as a brace.
what twisting motion are you talking about? do you mean the chassis flex?

yes the chassis flex. are you going to bash it or just run on road?
if you are going to bash if you come down on one wheel there is
going to be a lot of twisting in the chassis.

offroad all the way! the braces I already have are pretty strong and they make the chassis very stiff and the upper deck will remove all the unnecessary twisting.

my expectations of running the truck last week turned out to be unrealistic... Loads of unexpected work and other things did their job properly so I didnt have time to put it together:D
But I managed to make a support for the motor mount to get rid of any bending! It is made of 2x 4mm thick alu angle bar pieces, so it is an 8mm thick L-bracket mounted to both the chassis and the mount.
Image
Image
I couldnt make it look better, my tools are very limited, but it serves the purpose just right! It will look better after some polishing, but no time for it now.
I also made a servo mount. I used 4 pieces of an alu tube with 6mm OD and 4mm ID, 4x M4 screws and a PCB material. When tightened togehter, it is strong enough to give the support for this servo http://hobbyking.com/hobbyking/store/__ ... 1_8kg.html. A piece of chinesse junk when it comes to the quality, but it is quite strong.
A problem I had to solve was the room. You can see that there is not enough space in front of the motor mount. The problem in such a crampy area would be a pinion change. My original servo mount did not allow any manipulation with the pinion without disassembling either the motor mount, differential or the servo mount :D Not a nice solution at all, but these things can not be predicted without having all the parts mounted together in their places. So I made another one and this allows any pinion to be changed anytime.

Really liking this project, will be following it up.

Liked your method of sorting out the center driveshafts (dogbones) using a Lst2 CVD.

Never easy to craft something when your limited to tools. I wish I had more gear here to hand craft more pieces for my build. Well done for drilling through an axle because I've tried a few times and gave up due to the metal being so hard.

This budget build is coming along 8)

I glued a diff cup on the axle and drilled a hole between the cup openings where the arrow marks a red spot. that enabled me to drill a hole right through the center of the axle, although it took a long time.

the final look Image
without bumpers, upper deck and battery tray Image
Image
rear bumper skid plate cut
Image
baja 5t bumper had to be cut to fit my chassis
Image
Image
the whole front bumper
I used old savage 25 arms for the braces that connect the bumper to the bulkhead- it took som time to cut and trim them, hope they dont break soon :D
Image
1mm thick metal skid plate for the front bumper
Image
Image
Image
Image

things are finally getting some shape at this point
Image

currently working on the battery tray and the upper deck plate, they are already cut and drilled, but I dont want to hurry things up. I like to do things properly. Also having a bit difficult time at the moment with some other things ( nothing serious, but the hobby needs to be put aside) so the work on the RC does not get as much time as I need to finish it within a few days...
But I am sure it is getting close to the finish!

something big is occupying my room :D Image
just need to solder some cables on esc and find a gap in my schedule to run it!
I need to buy some black foil or tape to put it on the upper deck of the chassis because the PCB colour does not match the rest of the chassis

One member on here used the Losi XXL body on his savage. Think it was Liv4RC and the body looked big.
