Na'vi name for my airplane

[Niri Te]

I have a new ultralight legal, but aerobatic capable aircraft that I designed, and am now finishing building that I would like to give a Na'vi name to.
Because I do so much aerobatics, I would like to call her "Cloud Dancer".
I found "cloud", Pìwopx, and "dance", Srew, but I don't know how to turn the verb to the noun "Dancer". Could someone give me the word, AND teach me how to turn a verb into a noun?
I have a FINE teacher, but this is my first week with him, and I have bugged him enough this week, so no disrespect at all to him, I just want to give him a rest for this one question, and then I will continue picking his brain.
