Made what I suppose can be considered an rc plane, barely flies and doesn't have an elevator. I plan on making that pile of junk into something more competent, but I am feeling a plane building high, and sorta plan to make something bigger, I was asked if I had a structure to reinforce the inside of even this plane, so if I want a bigger and better one, that will be a necessity. My question is what would one use to reinforce a foamboard fuselage? My current plane is ~1 meter in both wingspan and body length, I want to idealy double it to about 2 meters, so it needs to at least withstand it's own weight.

Psu is chieftec powerup 650w, but part picker doesn't believe it exists.

Also any recomendations on case fans?

Will the pcmasterrace.org mid range build run better than the thinkpad E16, and will it run 1440p well, I gotta know if I'm comitting an absurd amount of money to a gaming computer.
