okay! been looking further into the project
and have some more questions 
so the pins going trough the wishbone and hub, where can I get those?
also the diff shaft, where can I get that?
is the diff front/rear the same?
Thanks 
(2 post in a shot time, sorry!! 
Pretty sure the diffs are the same.
I know people are using metal driveshafts and maybe someone will tell you which one, but there’s a printable one you just poke a (2x8mm IIRC, but check that) pin through each end.
I got all my pins and screws on eBay, so much cheaper than anywhere else I could find for small quantities!
@Dag_Elias_Sordal Yes, the front and rear diff’s are the same.
i posted my bom before, there are also central driveshafts listed!
for all the pins i got 3mm and 2mm titanium rods on ebay and cut them to size my self, works pretty well.
here is a picture of my setup: https://www.dropbox.com/s/jajssz34ruk0kwh/DSC01773-2.png
a correction to my bom: i decided to go for a WiRC-transceiver from dension,
its pretty cool. my son really likes it and i can record the video as well.
but its much more expensive than a simple 2.4GHz remote
@sicherlich_nicht thanks
I would love too see more photos of your car, If you have!?
thats the first one i took, still waiting for motor and ESC, cant do much more without it
