parts for T4'17

And the two parts it relates to are both above it on that page

that's a really long servo horn

All the new parts

interesting the packet says 2mm everywhere else it is stated as 3mm

The layshaft sits slightly lower creating a gap between the top deck. No need for shimming the whole thing anymore. The stiffener connects the new longer motor plate to the new hole on the servo mount.

The team were still shimming the top deck up 1mm despite the gap.

I imagine this is for the servo link to clear the topdeck without rubbing. Also, it stiffens the car slightly

I took some pictures of the new parts.
I expect a release before the weekend, it looks very good.
