Te Racer is btw based on the Defender. With the idea of having a huge vectoring engine capacity with the Xi'an engines. It has an aerodynamic shape and front exaust to gives the xi'an engines a great Manoeuver capabilities. For the others, I tried to extrapolate how Banu could handle cargo hauling. I start with the idea that they are merchant. So the cargo need to be quickly loaded and unloaded. So I find the tractor beam technologies really satisfying for that, and grabbing tech too (kind of docking tech?). So they are some kind of cargo dropper lmao
