What you read and what happens here in the UK are a world apart.

The class is a racing class, so development is inevitable. Another couple of seasons and it will all settle down. If we revise...

Quite wrong; this is not a clutch it is a differential.

Clutches need materials that go in and out of static friction as smoothly as possible. Arguably the worst clutch is metal to metal. In the...

Not worth it. It's very (very!) difficult to get them to work when the wheels have different lengths on the housings where the axles go.

Seems a bit misleading to me. Why is the AE ring not a complete 'sine' wave and why would I pay any additional amount to get an additional few microns of flatness?

Once the diff is done up to the...

I don't agree with that method. The tyres should be parallel to the arms of the vernier - 90deg to where you have them in your video.

Using the thin part of the arm only measures the tyre at that...

That must be why I never get anything like as good a mesh or diff action with other gears as I do with a Kimbrough. They must be 64DP and everyone else is between 63.5DP and 64.5 DP!!

That's a linear accuracy. CMMs create point clouds in 3D space so what's required is the volumetric accuracy, the repeatability and the bias.

I'll believe the TQ racing diff rings are flat, but the measurement is a crock.

For a start 0,001mm is 0.00004" (they've slipped a decimal place!) and to finish off that would be impossible to...

Shorty pack's a no-no - it won't fit under the shock. Get a Turnigy or Vapextech 1S - great value and good cells, especially the Vapextech.

Treads are still attached to a single carcass, so the same rules apply. The reason that they don't like treaded tyres is that the treads move around on the carcass (making the tyre more forgiving to...
