Hi
Dogfight Lite was for people to have a trial period before purchasing it. Since in the old days you could not "upgrade" your application from inside the game, it needed separate versions.
Fast forward to today, and every Android and Apple device allows for in-application purchases. Therefore, to avoid the current mess of having to update 2 applications per release, Dogfight Lite will be discontinued and Dogfight will be available to download for free.
Dogfight will run as a "lite version" and then give you the option to upgrade & pay inside the application.
I'm scheduling this to happen for Dogfight 4.0.9, a 4.0.8 version should be ready soon with some minor fixes.
