Tip Spin-help needed!
 

Hello
I have tried to get a tip Spin many times with my ultimate 120 (Goldberg)
I Let it fall stalled then apply down elevator and left aileron and rudder, the plane tries to get intoi the tip spin at a very low rolling-spining rate but I can not get it 100% tip stalled I mean the fuse is not vertical and it's not spinning in the tip, it's tilted.

With my extra I started in a flat inverted spin and applied full engine, the spin then it's flattened almost 100% and start tip spinning but honestly I don't know how to control it.
Any tip to get a proper tip spin like the ones I see on freestyle?
Do I need 3d Throws to do it?
Thanks in advance
Omar
