The bottom of the bulkhead caps are actually in the same position, they just have more material removed for better clearence if you run the axles in the high position . Top deck however is raised 1mm (a la shimming it like on the 6), and the caps also have more material under the shock towers... details

Did you just run kit set up Ed.

All geometry stuff was kit (so link and shock positions, roll centres etc).
Only changes I made were to use HPI silver springs front and rear, 450wt oil, drilled top cap and only 2mm of rebound (pretty much what I have on the 6).

Think as the traction came up towards the end of the day, should have tried 500wt, and taken back out the 0.5mm I put under the links during the lower traction period.

On the build side, one other thing I noticed (bar the steering drag link...see below), is that if you build the car to the link lengths as described in the manual, you get 1.5 front camber, 2 rear camber, and 0.5 front toe out... which is spot on what I run Thats a definate first for me and a tamiya kit!

Going back to how to get equal steering L-R, whilst I was setting the car up on Saturday, I played around a fair bit with the steering drag link, and servo sub-trim position, and basically ended up with the following. This give pretty much equal steering L-R (looking at my tranny I have both L and R on 94% EPA, even after the on track check).
  1. Remove 2mm from the ball cups in stage 8 of the manual (the ones that are built for the 4.5mm link).
  2. Build the link up so that the total length is 38.5mm (using overall length avoids mis-measurement from the ball cup cutting )
  3. When you get to stage 25, sub-trim out the servo to the right (cant the top of the horn to the centre of the car) to get the steering centred.

I know the above works for me and the servo I'm using (Spektrum S6040), although it maybe slightly different with different servo's, as they don't all have the same spline positions.
If it's slightly out, have a play with the link length and sub trim... but I've noticed on both the 6 and 7 that shorter seems to get the steering more equal.

On a different note, I was able to fit a small Kimbrough (black) spur gear by adding two holes with a body reamer. Not nearly as scary as I thought it would be. They even provide "circles" to guide you:



I'll try to post pics later!
Did the same thing a few minutes ago but I found a better way.

Put the new Kimbrough gear on the pulley as it shows in the directions. Now put the Tamiya pulley on over the kimbrough. The studs that go through the small pulley holes align the gears. Now, you can use the Tamiya gear as a drill guide for the two extra holes you need to drill. The big holes on the outside do the same thing so you can make holes to get access to the motor mount screws.

Worked like a charm.

Can you post setup sheet instead? It's a lot easier to visualize.

Thanks.
