All depends on your interest imo - that's the best part about the hobby! Scale? Speed? Relaxed flying? Foam? Balsa? Just some things to consider imo ... as for the Tubby, iirc user reviews weren't all that great, plane has a wallowing problem. You might want to try out Ailerons, in that case the E-Stater is a pretty good next step. You could also go for one of the flying wings (Zagi, etc) and have a plane that will handle windy days well.
