This is my version of the Apache AH-64. It features a deployable landing gear. It is very easy to print and does not require support settings. STL and 3MF (for multicolor) files included.

No suppots needed. I suggest using walls with at least 3 perimeters. Make sure you have good adhesion to the print bed, if necessary use an additive, in my case I use a bit of strong hold hairspray.
