Flying them is a bunch smoother then smaller planes but they do take some getting ued to. I went out and bought a 1/4 scale Extra 4th hand, paid about 150 bucks for it. An old Creek Hobbies Extra 300L ARF. Outsatnding plane by the way. I flew it for over a year while I was building a bigger plane. Ended up selling the Creek Extra for what I paid for it too. Landing wasn't a lot different, my big problem was flying it too far out, I kept it looking like one of my 60 size planes so it was way out there!! I do question going from a small electric to a big gasser though. It is comparing apples to oranges but you may be better off?? I did like most guys do and went from 40 to 60 to 120 size without any problems, my knnes do shake a bit with my 30% and I don't take off or land any of my friends 40% planes, I will fly them but I can't afford to replace them if something goes wrong so I don't do it often. I have only let one other person fly my 30% Extra and I was worried about it the whole flight.[X(]
