Honestly, if you're looking to run an aerial combat game with tabletop rules...I think you'll find running them on a forum very difficult. The two main rule sets that come to my mind (Imperial Aeronautica, and Fantasy Flight Games' X-Wing rule set). I know D&D has a few air combat rules for D20 Modern and D20 Future, but they're kind of clunky. I think there's also a few, more contemporarily set tabletop rule sets (Blue Max for WWI, Wings of Glory or Dogfight for WWI/WWII rules...also Birds of Prey for anything modern).

Sadly a lot of these games are hex-based and card-based, and not the most reliant upon dice or other internet-friendly mechanics, from what I've seen. 

Since you seem to be running a homebrew ruleset maybe a summary/once-over for your rules would be useful so we can see how/if it's a system that's actually easily convertible to an internet setting?
