Dissenting opinion on the trainers If you can only buy one , get the combat plane you like best . If you can buy two , consider a trainer ! I love the L 39 to death , and flying it seems to exponentially increase my skills in every other platform , including apparently unrelated types like the FW 190 . Trainers are the express train to high skill levels . I ' m not sure why . On the surface they look like you ' re getting less for the money . Why not just train in your combat jet ? In practice , though , flying the L 39 has worked wonders for me . My dogfight skills skyrocketed , I have precise control over whatever plane I ' m in , and far more accurate manual bomb and rocket delivery . I can ' t say why , exactly . It just works .
