I got this working by parenting the cloned arms to the Camera. I also had to clone the Humanoid and Shirt from the character for the character's appearance to apply to the new arms.
You can see the arms when you look down or jump.
LocalScript in StarterGui:
local Player = game.Players.LocalPlayer
local Char = Player.Character
local Cam = workspace.CurrentCamera
local Left = Char:WaitForChild("Left Arm")
local Right = Char:WaitForChild("Right Arm")
local FakeL = Left:Clone()
local FakeR = Right:Clone()
local RightW = Instance.new("Weld",Right)
local LeftW = Instance.new("Weld",Left)
RightW.Part0 = Right
RightW.Part1 = FakeR
LeftW.Part0 = Left
LeftW.Part1 = FakeL
local m = Instance.new("Model",Cam)
m.Name = "Fake Character"
Char:WaitForChild("Shirt"):Clone().Parent = m
Char:WaitForChild("Humanoid"):Clone().Parent =m
FakeL.Parent = m
FakeR.Parent = m

You do not have an explanation PLUS you cannot post the full script on the site. Read the rule book.
Its fine he did have an explanation!
I have explained it if you can't see the green comment I made. Also there nowhere in the rule book where it says your not allowed to give "full script" while explaining it!
