Bad news, didn’t get it all done before the sun went down. No tuft-test photos of this section of the build.

I like the look of the Fusion LSR, as well as several landspeed record cars I’ve seen. I made it even closer to the wings they use by adding a pair of spill plates. I think it looks funky and I like it. I understand the spill plates are for straight-line stability and can generate vortices as they slice through the air, but I put ‘em on anyway. I like em.

Iirc, I read through a rallycross aero article about wing design, and the wings that didn’t use any spill plates had poor performance, due to air falling off the ends. I wonder if that applies; I noticed consistent flow down the rear windshield as well as tufts converging from the C-pillars to the centre line of the rear glass. Either way, the flow is good indeed.


The stability seems improved as well. I don’t have my belly pan/airdam attached right now, and I noticed front end lift as well as oversteer at around 170 km/h turning a hard corner. On that same corner, I attacked harder and didn’t feel any lift off; front or rear.

Now to do it all again in coroplast! Big test run comes tomorrow morning!!
