body gyros not working as i thought?

The script is a local script inside a players gui, what i wanted it to do is rotate the characters body so it is facing what way the camera is facing, I thought this would work but the character doesnt even rotate.

p.s the prints at the end dont print anything

local plr = game.Players.LocalPlayer
local flying = false
local cam = workspace.Camera

function fly()
    local char = plr.Character
    local bgy = Instance.new("BodyGyro",char.HumanoidRootPart) bgy.Name = "B_Gyro"
    flying = true
    workspace.Gravity = 0
    local pos1 = char.HumanoidRootPart.Position
    char.HumanoidRootPart.Position = Vector3.new(pos1.X,pos1.Y + 5,pos1.Z)
    char.Humanoid.PlatformStand = true
    while flying do
        local lookv = cam.CFrame.LookVector
        wait(.1)
        bgy.CFrame = CFrame.Angles(math.rad(lookv.X),math.rad(lookv.Y),math.rad(lookv.Z))
    end
end

wait(3)

fly()

wait(3)

print(workspace.Plieax.HumanoidRootPart.CFrame)
print(workspace.Plieax.B_Gyro.CFrame)
