change bevel shaft to use tmaxx universal.
 

Scorpion's universal shaft have some problems. Then most of users change it to tmaxx's universal shaft, through processing making a hole to shaft. Drive shaft can be holed easily, but bevel shaft could not... Bevel shaft is more strong.
Then I chage that to Wheelyking's bevel shaft.

Wheelyking's shaft and Bevel gear.
