That track looks great,
Been loving my 418. Managed to win a local club championship ahead of the Yoks and X-rays (the only TRF418 there).
It's indoor and carpet (17.5) the car is so consistent and easy to drive fast, it's my favourite TRF since the 415msx.

How much thread lock do you guys use when building?
The last car I build with so much carbon/metal and metal/metal interfaces was a 1/8th has car. Used to need to use it EVERYWHERE!
And on threads, titanium v aluminium - thoughts? I notice the pros use a mix, but it's inconsistent where and when. I had been told the Aluminium ones are not as good when screw into metal and definite no go for al-al pieces. But plenty of builds I've looked at seem to buck that trend.
But also screws should be a fail (shear) point, so there must be some strategy to their use.
At the moment I've got enough Ti screw lying about to do the whole thing.

As for screws, I use a mix of Ti and Alu. On the lower deck all screws into the bulkheads, suspension blocks, and motor mounts etc are Ti. The only Alu screws I used on the lower deck are the 3 that hold on the front bumper mount. I also use Ti screws to attach the upper bulkheads and the damper uprights, for the top deck I used Alu screws. I seem to recall getting this formula from somewhere on here.

No problem Bill. It would good for some of your colleagues to give input on this thread as to what Tamiya is doing to address some of the challenges with the TRF418. It seems the car is doing well at club races but a lot of people also follow how the drivers are doing and when they see that they are struggling... raises questions about the new chassis.
