3 of the 4 seem like virtually the same plane in terms of how they fly. The Eagle is probably the easiest to fly, with the Venture and 4* being a small step up in performance.

Depending on your flying skills, and likes, it may make sense to build a more aerobatic or fun fly type plane in there??

Don't get me wrong, all good planes, just very similar. Which is no problem if that is the type of flying you enjoy. I would just think there would be some sort of progression in flying skills??
