I dont like warbirds a startup training type of plane..
Warbirds doesnt fly well, they arent really fun to fly until your a really good pilot.. I would even recomend the FT spitfire as a first plane..
All that said, I also believe that building is just as much fun sometimes as flying. So many people sees the 20sec as the planes life time.. But in actual fact, that plane was 150+ hours of fun..
