[chilly cloud]

local TimeTrials = workspace.TimeTrials;

for _,Model in pairs(TimeTrials:GetChildren()) do
    if Model:FindFirstChild("Start") and Model:FindFirstChild("End") and Model.Start:FindFirstChild("Arrow") then
        local Arrow = Model.Start.Arrow;
        local EndPart = Model.End;
        Arrow.CFrame = CFrame.new(Arrow.Position,EndPart.Position) * CFrame.Angles(0,math.rad(87.2),0);
    end
end```

and heres the model I was using. Just drag it into studio
