Both F15s are great. The avonds is slightly easier to fly due it is a bit bigger and easy on the eyes.. The skymaster is absolutely great if you want to have a great looking scale jet, stupendous to fly and above all, extremely practical plane to fly every weekend without worries and without pain in the back as it is lighter to carry than today heavier big jets. Also any mid sized turbine will power it as it should on a jet fighter.
