You guys may remember back when Lego made those Insectoid sets? Well, I got one in a blue bucket from a garage sale, but it either wasn't all there, or multiple sets....but anyway, I used some of the pieces and built a custom Insectoid. I used the stinger as the main body, and used what I believe are the wings as thrust focusers.
About this creation
That top photo is what it looks like from the front. You can get a good view of the front landing gear, and the lasers. On top of each side landing gear is a small directional thruster.
That is what it looks like from the back. You can see the little dish antennas on the back of each leg.
And that is what I call the thrust focusers. They basically take the thrust, and well, focus it. Those little jets under the main thruster are basically used for slower travel, or used to give it an upward boost.
