The airfoil wings start with a taper of .3mm so that should be good for a first layer height. Use as light of an infill as you can print well so that the wings are light. Set your wall thickness to .5mm so the main body doesn't need any infill to be solid (it is 1mm wide). Someone print this and tell me if it flies actually :) I also updated this from the last one so that the tail height is the same as the cockpit so that the tail doesn't get melted when printing the last few layers repeatedly. Now it should alternate back and forth the whole time so you can print this even without fans.
