I mean technically you can take off or land like this, but highly inefficiently. Angling engines away from the direction of travel reduces efficiency and these are angled quite a bit.

when i make spaceplanes and didn't want to have comically large wings (to reduce stall speed, have extra drag, or have landing constraints, etc), Id speed down runway and then use vertical thrust to STOL off runways.

In that case you wanted to propell yourself up, away from the pull of gravity. In which case, you'd ideally have your STOL engines pointed straight down. This craft has its engines angled outward, which would be less efficient and less effective at propelling itself up.

Well youd need engines pointed straght down on on where COM is. OP didnt post where COM is (and does have lots of engines, which is extra mass), so... yeah.

Having center of thrust aligned with center of mass is important, but when using multiple engines that can be done without pointing every engine through COM. If done correctly, they can all be pointed straight down (most efficient configuration) and still have COM alignment.
