- increase the speed of air hitting the underside of rear wing mainplane
- increase the speed of air exiting the diffuser.


Unless the benefit outweighs the cost. Lose a bit of speed during the flipping, gain enough while flipped, gain a bit in braking using this as a temporary airbrake. I can imagine this being hard to drive during braking.Martin Keene wrote: ↑19 Feb 2026, 11:02Surely that is the last thing you’d want to do with this rule set?

The actuator/s seem to be in the endplate.

The drag is less at start of straight because speed is lower.FittingMechanics wrote: ↑19 Feb 2026, 11:04Yeah plus the same motion happens when you activate SM, so if it acts as an aerobrake it acts both at the start and the end.Martin Keene wrote: ↑19 Feb 2026, 11:02Surely that is the last thing you’d want to do with this rule set?

Likely that aero brake effect is minimal.
I thought they didn't have front braking regen? So additional stopping power will be helpful, plus it's at the rear as well.FittingMechanics wrote: ↑19 Feb 2026, 11:04Yeah plus the same motion happens when you activate SM, so if it acts as an aerobrake it acts both at the start and the end.Martin Keene wrote: ↑19 Feb 2026, 11:02Surely that is the last thing you’d want to do with this rule set?

It's not energing suction at the diffuser from that location. It is too far from the diffuser throat for that.
Would it be possible for them to have both the actuation modes available at the same time?Martin Keene wrote: ↑19 Feb 2026, 11:02Surely that is the last thing you’d want to do with this rule set?
