[SOLVED] How to implement roll in aircraft flight script?

So far I have this simple plane flying script here

local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local shipPart = workspace.TestShip.PrimaryPart

local MAX_SPEED = 150
local SPEED = 50
local ACCELERATION = 1

game:GetService("RunService").RenderStepped:Connect(function()
	
	shipPart.BodyVelocity.Velocity = workspace.CurrentCamera.CFrame.LookVector * SPEED
	shipPart.BodyGyro.CFrame = CFrame.new(workspace.CurrentCamera.CFrame.Position, workspace.CurrentCamera.CFrame.Position + workspace.CurrentCamera.CFrame.LookVector)
	
	if UIS:IsKeyDown(Enum.KeyCode.W) then
		SPEED = math.clamp(SPEED + ACCELERATION, 0, MAX_SPEED)
	elseif UIS:IsKeyDown(Enum.KeyCode.S) then
		SPEED = math.clamp(SPEED - (ACCELERATION * 2), 0, MAX_SPEED)
	elseif UIS:IsKeyDown(Enum.KeyCode.A) then
		--roll left
		--shipPart.BodyGyro.CFrame = shipPart.BodyGyro.CFrame * CFrame.fromEulerAnglesXYZ(0, 0, 90)
	elseif  UIS:IsKeyDown(Enum.KeyCode.D) then
		--roll right
		--shipPart.BodyGyro.CFrame = shipPart.BodyGyro.CFrame * CFrame.fromEulerAnglesXYZ(0, 0, -90)
	end
end)

The plane will fly in the direction of the camera. I want the plane to roll when the player presses A and D, but I am unsure how to approach this. Can someone help me?

I found a solution

I created a variable called roll and incremented it by 1 or -1 when A or D is pressed. If roll ever comes equal to either 360 or -360, then it is reset to 0. I then multiplied this angle by the BodyGyro CFrame.

local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local shipPart = workspace.TestShip.PrimaryPart

local MAX_SPEED = 150
local SPEED = 50
local ACCELERATION = 1

local roll = 0
local rollFactor = 3

game:GetService("RunService").RenderStepped:Connect(function()
	
	shipPart.BodyVelocity.Velocity = workspace.CurrentCamera.CFrame.LookVector * SPEED
	shipPart.BodyGyro.CFrame = CFrame.new(workspace.CurrentCamera.CFrame.Position, workspace.CurrentCamera.CFrame.Position + workspace.CurrentCamera.CFrame.LookVector)
	
	if roll == -360 or roll == 360 then roll = 0 end
	shipPart.BodyGyro.CFrame = shipPart.BodyGyro.CFrame * CFrame.fromEulerAnglesXYZ(0, 0, math.rad(roll))
	
	if UIS:IsKeyDown(Enum.KeyCode.W) then
		SPEED = math.clamp(SPEED + ACCELERATION, 0, MAX_SPEED)
	elseif UIS:IsKeyDown(Enum.KeyCode.S) then
		SPEED = math.clamp(SPEED - (ACCELERATION * 2), 0, MAX_SPEED)
	elseif UIS:IsKeyDown(Enum.KeyCode.A) then
		--roll left
		roll = roll + rollFactor 
	elseif  UIS:IsKeyDown(Enum.KeyCode.D) then
		--roll right
		roll = roll - rollFactor 
	end
end)

If someone else thinks they have a better solution please don't hesitate to let me know! Thanks

for left:

elseif UIS:IsKeyDown(Enum.KeyCode.A) then
        --roll left
	local TS = game:GetService("TweenService")

	local tweenInfo = TweenInfo.new(1,Enum.EasingStyle.Cubic,Enum.EasingDirection.InOut,0,false,0)
	local goal = {}
	goal.Orientation = shipPart.Orientation + Vector3.new(45,0,0)	

	local leftTween = TS:Create(shipPart,tweenInfo,goal)

for right:

elseif UIS:IsKeyDown(Enum.KeyCode.D) then
        --roll left
	local TS = game:GetService("TweenService")

	local tweenInfo = TweenInfo.new(1,Enum.EasingStyle.Cubic,Enum.EasingDirection.InOut,0,false,0)
	local goal = {}
	goal.Orientation = shipPart.Orientation + Vector3.new(-45,0,0)	

	local leftTween = TS:Create(shipPart,tweenInfo,goal)
