Unnamed rally car project (1/10)
 

So, decided to build a 1/10 rally car with a center differential and belts instead of shaft. Did some thinking and drawing and ended up with this. Based on a Xray XB4 high volume differential. Put the diff case in the lathe and removed the bottom. Made a new out of 6082-T6 aluminum. Used a diff cross pin from Xray X1 so the bevel gear axle could run through the differential. The concept worked. [emoji16]

Version 4 of the differential since the first 3 wasn't long enough. Had to "make" a new spur since Xray don't have a 87T for their differentials, only for their slippers.https://uploads.tapatalk-cdn.com/202...11942756d1.jpghttps://uploads.tapatalk-cdn.com/202...ac1ca29424.jpghttps://uploads.tapatalk-cdn.com/202...1122cdc92d.jpghttps://uploads.tapatalk-cdn.com/202...3e7d64572c.jpg

First batch of belts came. So cool to be able to just make a phone call and order the belts you need for a fraction of the price Tamiya or any other brands charge and have them delivered 2 days later [emoji108]
Only problem is that I ordered too short rear belt [emoji58][emoji58][emoji58]https://uploads.tapatalk-cdn.com/202...f27a94d7b6.jpg

Moving the servo to the Center of the car requires a new part for the steering. And since I can't buy what I need, I had to make one [emoji854]

This is what it looks like today, it's too wide at the moment so I'll have to manufacture some differential mounts so I can use the XV-01 suspension mounts instead of the TA-06.
The differential will be mounted on the suspension mounts instead of the chassis to get the clearance needed for the XV-01 suspension arms. https://uploads.tapatalk-cdn.com/202...a0fd5029c2.jpg

Wild man. Some out if the box thinking going on here.

Is the center diff still sealed?

Re: Unnamed rally car project (1/10)
 

Yes, sealed and filled ��
But I might have to make a fifth version, not entirely satisfied yet.

Just found this thread, very interesting project! What has happened to the car since the last post, is it completed? I would love to see and read more about this kind of car building.

Re: Unnamed rally car project (1/10)
 

Curious on how this will end

Re: Unnamed rally car project (1/10)
 

Me too.

Any updates?
