No flight engineering mods are used to aid my flights, meaning achieved feats could be improved upon by those who choose to use them.

My designs slightly prioritize looks over performance, usually optimized for range, cargo capacity and sometimes speed (in that order). They are all designed in science mode so cost-wise, the may not be for you.

Disclaimer: a lot of my craft are from older versions of the game and are likely no longer able to achieve the feats that they advertize
