i wouldn't go as far as to say that a cub is a relaxing flyer. i'm far more relaxed flying my "sport" planes like the decathlon (citabria) than i am with my cub... personally, i think the cub is harder to get off the ground than the sport flyers... but i'm flying the WM Cub 26 which is miniscule. why? the cub is big and clunky while the decathlon is nimble. the cub is generally underpowered in RC terms while the decathlon is generally overpowered. the big difference i think is in the kind of flying you want to do. if you want to do scale flying with limited acrobatics (not very axial rolls, not very round loops, very pretty hammer heads and equally nice stall turns, and the very occasional cubans) you're okay with the cub, but if you want to do pretty much all the standard sport aerobatics, get the decathlon.

the challenge of flying the cub is to make it as scale as possible. it makes you a better pilot. i hate to see people flying cubs that are overpowered and sliding all the way through the turns because they don't know how to use the rudder. the love of flying the cub is to get the turns coordinated using the rudder to turn and ailerons to hold it through the turn. too little and you're draggin the tail around the turn. too much rudder and go into a spin. fun! and talk about ground looping... my cub is the worst. when i put together my 81" TT, i'll let you know what i think about that one.

the decathlon might be a handful on the ground, but in the air you're back to sport flying you can only do on an overpowered RC plane... it's fun... but then it's a different kind of it :-) on that note, i love my citabria because it does everything i can do with any non-3D plane but does it with such class.
