im trying to get this brick to rotate when i move my mouse down but it will go insanely fast if i move it even slightly, and when it slows down it will suddenly go fast again even if im not using my mouse.

link to a video of the problem https://gofile.io/?c=uSpnf1

my code

local players = game:GetService("Players")
local player = players.LocalPlayer
local Uis = game:GetService("UserInputService")
local runService = game:GetService("RunService")
local part = workspace.Part
local bg = Instance.new("BodyGyro")


local function move(mdy)
	bg.CFrame = bg.CFrame  * CFrame.new(0,0,0) * CFrame.Angles(math.rad(mdy),0,0)
	print(mdy)
end

runService.RenderStepped:Connect(function()
	local mouseDelta = Uis:GetMouseDelta()
	bg.Parent = part
	part.Position =  Vector3.new(0,5,0)
	bg.MaxTorque = Vector3.new(1,1,1)
	bg.P = 10
	if mouseDelta.Y > 0 then
		move(mouseDelta.Y)
	end
end)
