Parts sent flying?[fixed it]

I have this model being moved by a body velocity, but it's in a really weird shape, and whenever I step on it, it flies off the baseplate and gets destroyed. I tried using :SetNetworkOwner() for nil and player, but it didn't help. I was thinking of doing something like this:

if game.Workspace.WeirdLookingModel.PrimaryPart.Position.Y > 50 then
	game.Workspace.WeirdLookingModel:SetPrimaryPartCFrame(CFrame.new())--but then how do i get the position i need.
end

So yea, what do I do?

Im not that good but MAYBE! Anchor l it?

while true do
game.Workspace.WeirdLookingModel.Anchored = true
wait(0.1)
game.Workspace.WeirdLookingModel.Anchored = false

Fixed it. Thanks to Perci1, who suggested that i turn PSGPhysicsSolverEnabled to true, it already was true, so I set it to false, and lo and behold, the model didn't ping off when I stepped on it.
