You can also use any of my XML parts and custom weapons if you want, as long as you give credit.

2 ways:
Easy way-- you don't.
Hard way-- become friends with @ChiyomiAnzai and learn their secrets.

@MrHoboDuck loads of luck/ xml.
Genuinely xml modding parts can make a rotator look like a vent or battery, longer fatter beacon lights look really good.

Then also get some building mods like overload, designer suite, fine tuner and more these help with precision parts and xml.

Also a quick tip, put fuselage over plane wings

Hide car engines (unless they are wanted visible)

And work on more intricate shapes, curves look good on planes (unless more blocky designs are wanted) this is made easier by finetuner

Lol ok @CrashFighter05

it takes years to get that good. I'm only getting half decent from 2 years of experience.
