im flying a trainer self taught trust me under no circumstances get a low wing plane to learn on!!.as far as speed goes trainers are not slow but the big pluss is they can be flown slow unlike other types of planes!!.get a propper trainer youl learn more without the fear of crashing if you get too slow.as others have said you can put a larger engine in later and do all kinds of crazy things if you like.leave the low wing plane till later trust me you arent ready for it!!!.also the guy who suggested building another wing with no dehederall is spot on that would be a great idea and wont cost much especially if you build it from plans!!.
