Make a Projectile spin?[Solved]

I've been trying to do this for more than a month now and what I've noticed is that it's nothing but glitchy.

AngularVelo.AngularVelocity = Projectile.CFrame.lookVector * 200

is where I'm having trouble.While the part is moving forward from the Torso's lookVector The part spins for 2 seconds untill it stops spinning how it's suppose to. It fades out of it's axis(Z) to a mixture of the other two. I tried bodygyro to control it but I don't know how to control it when the AngularVelocity of part is the lookVector of it * 200. I did try lookVector of the BodyGyro's MaxTourqe to do that but it didnt work.

Please Help I've been trying to fix this for months. I will reward some nice Rep for whoever can find the solution first, thank you.

Try it yourself and see if you know the solution:

Projectile = Instance.new('Part',workspace)
Projectile.Size = Vector3.new(5,5,15) 

projectilePosition = (Character.Torso.CFrame * CFrame.new(0,3,-20)
Projectile.CFrame = projectilePosition

BodyVelo = Instance.new('BodyVelocity', Projectile)
BodyVelo.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
BodyVelo.Velocity = Projectile.CFrame.lookVector * 200
AngularVelo = Instance.new('BodyAngularVelocity',Projectile)    
AngularVelo.MaxTorque = Vector3.new(100000,100000,100000)
AngularVelo.AngularVelocity = Projectile.CFrame.lookVector * 2000
