Body velocity not changing when rotated?

Help and Feedback Scripting Support
#1

So i’m trying to make a plane, and for some reason when i turn it wont go to the new way.
my code:

local Speed = 50
local MaxSpeed = 10000
local TurnSpeed = 3
local Seat = script.Parent
Seat.Changed:Connect(function(property)
	if property == "ThrottleFloat" then
		
		Seat.Parent.Base.MoveForce.Velocity =  Seat.Parent.Base.CFrame.LookVector * Speed * Seat.ThrottleFloat
		
	end
	if property == "SteerFloat" then
		Seat.Parent.Base.RotationForce.AngularVelocity = Vector3.new(0,Seat.SteerFloat * TurnSpeed, 0)
	end
end)

any help would be apreciated

Pretty sure its AsemblyLinearVelocity and AssemblyAngularVelocity. Unless these are the names of your Body Movers?
