Not the prettiest thing I have ever build but,Probably most reliable and useful ground vehicle, This thing can climb up to 80 degree mountains,Can go fast as 60ms with rover wheels,And more than that if you open landing gear. Jet engine is for helping to climb or gaining more speed. Aaaand,Yes. It can Fly. It has stable flying style,easy to use, hard to land,but not impossible. I managed to land several times but It also has built in parachutes,So landing wont be a problem.
