So any tips anyone wants to share
One tip would be to use all the flat head screws without lettering on the bottom of the chassis wherever possible as they fit closer to flush than the ones with the lettering stamped into the heads.
They are the shorter (5mm) of the two and apparently from a different vendor so the heads are slightly smaller in diameter.
2) You will need to be sure to press the diff locking nut all the way into it's seat as it fits quite tight and some have complained that the screw that goes into it is too short. it's just that the nut is not seated all the way.
3) Sand the edge of the shock pistons with 400 grit sandpaper to remove the burs. This will make them work smoother.
4) I had to shim the lower shock mounts 2mm at the rear of the car as the springs tend to rub. I will take some pictures of all this stuff later.
5) some motors have an issue where the flat spot on the shaft doesn't extend far enough toward the motor bearing which can cause a poor alignment with the spur gear. D3 motors are like this. You will have to grind, file or machine the flat to about 1mm from the bearing face in order to have enough movement.
There are other building tips in this forum, you will just have to look around a bit.
Good luck in you build...
