MP777 SP2 Brushless

[lincpimp]

The century pinions are not hardened (not enough to work with a steel spur). Get a kyosho plastic spur, it should fit that diff just fine, 46t should be you best bet. Also you may want to upgrade the novak to a 5mm shaft rotor. I broke my hacker c50 maxx 1/8 motor shaft yesterday and others break their novak shafts too.

Otherwise the buggy looks good. I would find a way to tie the tops of the center diff bulks together, it will help the pinion/spur mesh stay more consistent.
