Wltoys 12428b (part 24: Fixing front toe out)

From standard these cars come with a toe out that's quite visible.  When i measured it (I am not an engineer..) it seems about three degrees each side (with the standard fixed, equal length 61mm steering arms).  I did this by:

1. Placing the car on a piece of paper, aligning it perpendicular.
2. Place a straight edge along the front wheels, draw a line (the outside ones)
3. Then rule progressive parallel lines towards the centre until they cross.
4. At the crossing point, use a protractor to measure the angle.
5. Halve that number to indicate the toe out for each wheel.

Such science!

Then we need to make up some adjustable steering arms so we can alter the toe.

Attempt 1: I cut the heads off some random bolts and screwed in the spare piston ends from the CVA shocks.  This would have worked, however, they're non adjustable.  Worse, I cut down the only bolts I had, and they were too short.. I really could have gone and got some more, cut them to the exact length.

Attempt 2: Buy some adjustable steering arms.  Ended up getting the Tamiya 54539 Full Turnbuckle Set. I fitted them in the following combination to yield an adjustable arm of nominal length 61mm:

Long story short, after a bit of mucking around I was able to produce 3 degrees toe in with equal length steering arms of 60.60mm.  That's about as good as I am willing to attempt right now, mainly because there will be wild variations in actual steering because of the play in the plastic steering mechanism.
