V-Stretch drive shaft length for 50mm ext?

[o0wiz0o]

RC Monster V-Maxx Chassis with V-Stretch 50mm Extension. Makes the truck look much more proportional and handle better too from my initial impressions. Size is in line with a Savage XL now.

To get a 160mm rear shaft that will fit stock diffs I had to get creative using the stock male center shaft and the female drive shaft for the wheels.

Together they do meet but offer little contact and the connection feels weak. Even the 4s I run would twist the shafts. So I cut the male remainder off the drive shaft and glued and slotted these two pieces together on some wooden dowel. The dowel is cut and left in place.

This has lead to a solid shaft. I have tested on high traction tarmac on 4s and it has held up so far... :)
