Between owning those tropical islands and something like 80% of the world's desert, I think it's safe to say that I have enough oil to drown the both of your infidel nations. :sun

Well in any case, Tin would no doubt be at least interested in buying aircraft and they'd prefer to do it from someone that makes quality products and doesn't hate them. Your elves would fit the bill. Aside from coal and oil, Tin also has a lot of mountains and therefore a  healthy mining industry. There's also forestry, fishing, agriculture, ranching...Tin has an over abundance of raw materials and a lack of manufacturing, so they would be looking to supply more industrialized nations in order to import finished goods and tech products.
[/quote]Plants and natural oil could be good exports since like I said elves hate the smell of burnt gasoline or petrol-derived diesel.
As for aircrafts...well, you may not wish to fly a vehicle designed for elves.
Elves have natural gyroscopes and can literally tell how fast their aircraft is going without needing devices to tell them. Their lighter aircrafts basically ditch most of the aviation gear you know and need and let the elves pilot it on nothing but their senses and instincts alone. They have a radio, a map and a compass... that's about navigation for elves.
Controlling the biodiesel-electric hybrid push-pull twin propeller engine and the sharp Gs accompanied with their overpowered design is also an issue.
Lastly, you may be frustrated because unlike typical fighters, most elven designs don't like installing surplus weapons to increase rate of fire... they prefer not missing so much.

Really, getting a seasoned human pilot in the cockpit into an elven fighter is a sure recipe for a disaster.

Seriously, just look at it. It's less of a fighter and more of a manned air torpedo armed with a single autocannon.
