thank u. i say im a beginner. i built a dumas hotshot 45 hydro years ago and had a blast. loved building and still do, but that was long ago and havent built any models since, well till now. i was pretty sure i needed to sand radiuses, but green i am and away from the hobbies many years. a wise man will say i dont but a fool will just well. thanks again to you all for the help.
I race scale hydroplanes and can tell you that running a boat in two dimensions is a whole lot different than flying a plane in three. Blow over the boat and you just go get it. Crash a plane and you break out the broom, dustpan and garbage bag. As I said, if you want to fly, get a legitimate trainer and learn on it before you try to fly that Cub.
