Quoting Jason Brehm
All you did was snap off a wing from a TIE fighter and put it on the top!
I am fully aware that this creation is more or less a "TIE fighter with only on wing(on top)" however if you look closely at the details I have changed a few things. I hope no one takes this model too seriously because all I have really done is remodel a TIE fighter set. I hope this explanation has been sufficient.
