What is wrong with this model relocator?

script.Parent.ChildAdded:connect(function(child)
	if (child.Name == "SeatWeld") then
		local Char = child.Part1.Parent
		local Human = game.Players:GetPlayerFromCharacter(Char)-- Relocate
		if (not Human) then
			return
		end
		local heli = script.Parent.Parent
		heli.Parent = game.Players.LocalPlayer.Character
	end
end)

script.Parent.ChildAdded:connect(function(child)
	while wait(0.2) do
		if script.Parent:FindFirstChild("SeatWeld") == nil then
			local Char = child.Part1.Parent
			local Human = game.Players:GetPlayerFromCharacter(Char) -- Locate out (if left seat)
		if (not Human) then
			return
		end
		local heli = script.Parent.Parent
		heli.Parent = game.Workspace
		end	
	end
end)

This is placed in a seat. It works perfectly fine in studio but in server mode, the helicopter model doesn't move into the player model
