RE: intermediate or not?
I haven't flown this particular one, but I have flown lots of different quarter scale cubs over the years. There is nothing particularly demanding of them. Once they are in the air, they fly like any other airplane, however being bigger and heavier than, say, 40 sized models, they fly smoother, and are less bothered by wind and turbulence (up to a point). The bigger ones have such a long wheel base that the ground handling is pretty decent - except if there is a crosswind blowing, then you will find it likes to keep taxiing into the wind, regardless of what you are telling the tail wheel to do. The gas engines require a different technique to start and run, as well as a healthy respect for the bigger props that they swing. But there are many, many advantages to going with gas.
The full span Cubs don't roll that well, and inverted flying is an unnatural act, but you can do stall turns, loops and lazy 8's all day long. They do a real pretty spin, but I still find it tough to get one into a spin cleanly. Their forte is circuits and touch and go's Fly them slowly enough especially around sunset, and people remark how much it looks like the real thing! Put it on floats, and you have another wonderful world to explore.
Strange as it may seem, smaller cubs are more squirrelly and difficult to handle on the ground ,and (at times) in the air. Stick time on a smaller cub is almost (but not quite) useless as they fly so differently from the bigger ones...However, the one exception to what I just said is that it teaches you to use your rudder thumb If you don't use the rudder appropriately, it is painfully obvious to anyone watching !
Have fun with it !!
