Most of the time I spend in DCS, I'm a Hog driver. I bought the AV-8 a few weeks ago and it's a lot of fun. VTOL is real fun and makes a lot of scenarios possible, that the Hog can't keep up with. Of corse, the Hog was built for other tasks.
The AV-8 is in EA, so I'm quite pleased with the functionalities that are available at the moment. There may be some problems, but it's still fun to fly. But with the Viper around the corner, I think I won't have much time left to fly the Harrier. :)
