Default Redcat Shredder V2 build thread and info

I will update this post as best I can with info regarding the build of my Redcat Racing Shredder V2. I just got it earlier this week so I'm still learning about it.
I am running it on two 2s 50c batteries and it's a blast! I put in a SkyRC GC-401 Gyro.


I am trying to compile all the info I have found from various forums, FBook posts, and YouTube videos into one source.

Differential:
Differential shims/washers. The part number for the washers/shims for the diffs is "Redcat Racing BS903-091" the size of the washers is "5.2*10*0.2"
I believe that you are supposed to use 1 - 2 washers per diff.
Diff Fluid: Posts I have seen recomend using 80k to 100k for the front and rear diff, and 300k all the way up to 1million in the center diff. I have 100k and 500k weight coming in next week.

Shocks:
I am going to be swapping out the shock oil with 75-90wt oil.
I think the springs might be not stiff enough for the weight of the shredder. I'm going to measure the shocks and springs with my caliper. I will post those measurements here.
Once I have taken some time with adjusting the spring preload and put the heavier wt oil in, I will look for stiffer springs and post a part number for what I find.

Motor Mount:
I read that the Redcat Racing Bs803-022 Aluminum Motor Mount fits the shredder.

If you have any info PLEASE post it and be as detailed as you can with part numbers or what parts from other vehicles swap over with little to no modification or even heavy modification.

So I put 100k in the front and rear diff along with 2 of those washers and 500k in the center diff with 2 washers. I watched these 2 videos for disassembly

Welp! My center diff exploded lol. I have read that you can use Arrma 6S diffs for the f/r and center.
Here is a video to the arrma center diff swap: youtube.com/watch?v=wpQkkuhEDNI&feature=youtu.be&fbclid=IwAR2VUGToNJTE4Dqdgw5Ouau5-ik5yK-_OPdhppzbtRyK_Ug4HpNHsfqnhVU
someone on facebook commented that this is all you need to do for the center diff. "only need to swap the arrma cups to the shedder cups everything else is the same for the center"

For the front and rear diff this is what someone else commented "So the internal gears and the diff housing from the arrma work. The cups and spur gear ar the shredder. And you will need one bearing. Other then that it fits" and gave the following part numbers "ara310433, ara310436" which is a good bit cheaper than buying the whole completed diff. Before I do the swap I am going to see if anyone comments if it's worth the $$$ to get the BLX stuff.
