Helicopter Physics HELPP

[Sherlock_999ALT]

PLEASE READ BEFORE RESPONDING

Context:
I have created a working helicopter, but I have an issue with the cyclic (the joystick thingy).

The joystick control how the helicopter moves and is implemented through an Angular Velocity. The vertical thrust is implemented through a Vector Force.

Problem:
When the joystick is held forward on a real life helicopter, the helicopter will move forward without falling into a front flip.

My helicopter will fall into a front flip no matter how far the joystick is pushed forward. I want the helicopter to fly normally with the joystick held forward, but then do a front flip if the joystick is pushed too far forward.

I don’t want to use an Align Orientation because it will be impossible for the helicopter to do a front flip.

This is basically what happens:

My code:

-- Services
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local ContextActionService = game:GetService("ContextActionService")
local UserInputService = game:GetService("UserInputService")

-- Variables
local localPlayer = game:GetService("Players").LocalPlayer
local character = localPlayer.Character or localPlayer.CharacterAdded:Wait()  
local humanoid = character:WaitForChild("Humanoid")
local heliGui = localPlayer.PlayerGui.HelicopterGui

local camera = workspace.CurrentCamera

local helicopter
local vectorForce
local dragForce
local angularVelocity

local collectivePercentage = 0
local turnForce = 0
local goingUp = false	
local goingDown = false
local turningLeft = false
local turningRight = false

-- Controls 


-- Main Functions
function inputControl(actionName, inputState, inputObject)
	if inputObject.KeyCode == Enum.KeyCode.W then
		goingUp = inputState == Enum.UserInputState.Begin
	end
	if inputObject.KeyCode == Enum.KeyCode.S then
		goingDown = inputState == Enum.UserInputState.Begin
	end
	if inputObject.KeyCode == Enum.KeyCode.A then
		turningLeft = inputState == Enum.UserInputState.Begin
	end
	if inputObject.KeyCode == Enum.KeyCode.D then
		turningRight = inputState == Enum.UserInputState.Begin
	end
end

function addDrag()
	local velocity = helicopter.PrimaryPart.AssemblyLinearVelocity
	local speed = velocity.Magnitude
	local dragDirection = -velocity.Unit
	local dragMagnitude = 6 * (speed ^ 2)

	dragForce.Force = dragDirection * dragMagnitude
end

function addCollective()
	if goingUp then
		collectivePercentage += 1
	elseif goingDown then
		collectivePercentage -= 1
	end

	collectivePercentage = math.clamp(collectivePercentage, 0, 100)
	local collectiveForce = helicopter.PrimaryPart.AssemblyMass * workspace.Gravity * collectivePercentage / 100 * 1.4

	vectorForce.Force = Vector3.new(0, collectiveForce, 0)
	
	heliGui.Collective.Text = collectivePercentage .. "%"
	
	local hinge = helicopter.Rotor.RotorShaft.HingeConstraint

	hinge.AngularVelocity = collectivePercentage / 2
end

function addAngular()
	local mousePosition = UserInputService:GetMouseLocation()
	local mouseX = (mousePosition.X - camera.ViewportSize.X / 2) / camera.ViewportSize.X * 2
	local mouseY = -(mousePosition.Y - camera.ViewportSize.Y / 2) / camera.ViewportSize.Y * 2
	
	if turningRight then
		turnForce = -50
	elseif turningLeft then
		turnForce = 50
	else
		turnForce = 0
	end

	angularVelocity.AngularVelocity = Vector3.new(-mouseY, turnForce, -mouseX)
	
	heliGui.Cyclic.Text = math.round(mouseX) .. ", " .. math.round(mouseY)
end

-- Connection Event
humanoid.Seated:Connect(function(isSeated, seat)
	if isSeated and seat.Name == "VehicleSeat" then
		helicopter = seat.Parent
		
		vectorForce = seat.Parent.VectorForce
		dragForce = seat.Parent.DragForce
		angularVelocity = seat.Parent.AngularVelocity
		
		ContextActionService:BindAction("InputControl", inputControl, true, Enum.KeyCode.W, Enum.KeyCode.S, Enum.KeyCode.A, Enum.KeyCode.D)
	else
		ContextActionService:UnbindAction("InputControl")
	end
end)

RunService.RenderStepped:Connect(function(step)
	if vectorForce then		
		addCollective()
		addDrag()
		addAngular()
	end
end)

Could you just clamp the forward rotation depending on how much the forward stick is held down? Like if the forward stick is held 50%, lock the forward rotation at a maximum of 45 degrees, just as an example.

You could try do this manually with if statements, or figure out your own formula to work it out.

Thanks for the help. I gave up and just used align orientation. It works fine but no flips
