After tightening down the wheel nuts, my first major issue appeared...
The wheels are Pro-Line's Renegades PRO2725-03 intended for use on the HPI Blitz, Ultima SC6, Jammin SCRT 10, and other RCs that use the Traxxas Slash (rear)/Slash 4x4 offset.
The problem? Tekno's wheel hexes are not wide enough and/or the Pro-Line wheels have too much material; making the wheel's socket too deep. When I go to tighten the wheel nuts, the extra plastic that is .41~.70mm above the wheel hex (in picture) rubs on the hubs. So much rubbing that the wheels are almost unable to be turned by hand. So annoying. Ordered wider hexes to resolve the issue.
