Perhaps you should specify which one you have.
The Power of the Primes/Combiner Wars Elita-1 turns into a jet, and a torso for a combiner name Elita-Infinite. They gave it another name too, but I forget what that is.
There was also a motorbike version in the Michael Bay movies. This one would be a pain to transform, as it has a wheel for a unicycle type of leg.
I think she is also included in the 3pack from the Studio Series that just came out. In the movies, I believe they were just referred to as the Arcee twins. Elita-1 has been a repaint of an Arcee botorbike a few times over the years.
TL
R, which one are you referring to? and did you follow the instructions?
