The Chaos Hellblade is an absolutely iconic 40K fighter plane. Imperial fighters tend to be Hawker Typhoons - heavy, brutal, blocky - but the Hell Blade is a Spitfire - light, elegant, agile.
Forge World used to make a Hell Blade but it has been withdrawn, possibly for remodelling as the quad-autocannon are gone in the new datasheet.
The new Hell Blade has twin guns. I have located them on top of the wing because that is the visible part of a fighter model and scratch-built models often are too 'clean'.
The Hell Blade is normally piloted by a hard-wired servitor and/or a daemon. There isn't really room for a pilot.
I found a paper-plane template on the web for scale and the shape of the main body parts and wings.
The plane is made from card, reinforced with white glue, and straws. Only the guns and sensor packs on the wings are from plastic kits.
It is painted with commercial primer, to smooth out the surface, Humbrol red spray can paint, as a base colour, and a light coating of Tamiya metallic red.
Okay, it not as good as a Forge World resin model but that will cost you the best part of a ton (assuming you can find one), and this cost pennies.
