Christian Horner says Red Bull are aware of the fluttering rear wing on Max Verstappen's RB18 car and will try to fix it in time for Free Practice 2 at the Azerbaijan Grand Prix.
Verstappen's rear wing appeared to be fluttering and flexing down the long straight at the Baku City Circuit when the DRS (Drag Reduction System) was opened.
The flexing has already caught the eye of Red Bull's rivals. When asked if the likes of Ferrari and Mercedes could soon complain to the FIA, Horner laughed as he told Sky Sports F1: "I think they already have!
"Obviously, we've seen it we've got the data from it, we've got the comparison to Sergio [Perez's] wing, so I think there's some modifications or some tuning that we need to do just to make sure that we eradicate that for this afternoon."

Horner: It's not enhancing our performance
Despite any complaints about the Red Bull rear wing that may have come the FIA's way, Horner says there is no lap time to be gained from running with what he says is a malfunctioning rear wing.
Horner was also asked whether the problem has been caused by yet more Red Bull weight-saving, with the team still trying to bring the weight of their car closer to the 798kg minimum limit.
It comes after Verstappen faced mid-race DRS problems during the Spanish Grand Prix, caused by the team looking to shed weight heading into the weekend.
"Weight is always a critical factor and you're chasing that obviously all over the car," Horner said.
"But there was a difference between the [two] cars so we just need to look at the set-up of it and the rigidity of it and hopefully we can get on top of it for this afternoon.
"It's not enhancing performance. The guys are into it and, hopefully, we'll get it resolved for the next session."
