if you want to keep low on the cash but not miss out on any of the fun stuff than i would recommend the twist 3d from h9. it will work really well with a 50 two stroke and have unlimited vertical. it is a smaller model. as you get into the 60 size models, stuff is going to get more and more expensive, and if you want to get into some of the more 3d oriented models you will be needing better servos than just standards. out of all the planes mentioned here, the twist is by far the easiest to fly. it should float better than a trainer but it will do some pretty crazy aerobatics that most of these models here will not do. it also looks kinda cool and it's size is unintimidating when you want to low stall stuff. the twist is only 47 inch wingspan, but i would not just pass it up for it's size. check it out, i highly recommend it. that was my 4th gas plane, but i have flown many models and demo'ed them and i really loved that twist. i am not ruling out the other aerobatic models, but in a 60 size, i think you may be kind of unhappy with them. 60 size models that look like the real ones have a tendency to be heavy and snap-rolly, simply because of their size and all kinds of complicated stuff that i don't know about. while some are better than others, you will never really find one that you can do some extreme stuff later if you want to with. if you don't really care about any particular type of flying and you are just lookin for a new plane, any plane will suit your needs. if you want to do a specific type of flying, certain models will be ideal and certain will never hit your expectations. before we can really answer your question, we kinda need to know what type of flying you want to do to really recommend a plane that is tailored to your needs. different styles like just flying around in circles, sport flying, scale, pattern, racing, 3d, stuff like that. as i said, if it does not mater to you than any old model will do.
