Speaking of World Models covering... I just freshen up my skyraider. The covering wasn't that bad, but the fuse covering slowly was peeling so I ripped off the basketweave printed covering and replaced it with Ultracote. I did a little of the same for the wing root too. In all honesty the covering wasn't that bad. This plane is a year old and has about 250 flights on it, 99% of those flights are full throttle downlines, knife edge, and high G tumbles, and it's still holding together. Great deal for 69.99. Only downside is it's a butt ugly plane, but that adds character!
