Dont remember for sure. I got it as a gift and messed around with it a couple of times. I did try doing all three on a few and wasnt real satisfied with the result. I then tried replacing single vanes on ones that I didnt do and it didnt work. I put it away after that and never got it out again.
After seeing the other replies I am thinking I may have put it away too soon. I think I will be unburying it and giving it a second chance.
