Never any problems landing or taking off. This airplane flys like a trainer, slow and stable. I've never deployed the flaps on landing, the airplane floats when landing. The bellcranks work just fine and I would follow the plans if you are not an experienced builder, but if you are talented I might go with a servo for each airleron. My airplane is covered with monocote with exception of the tail feathers which are some kind of iron-on fabric and painted. The bottom of the wing has a check pattern. At the time the local hobby shop had only the smaller checks so I used it; I would have prefered the large checks like on the full scale airplane but no one has noticed the difference. It would have taken just too much work to cut squares out of the monocote and place them onto an all white covering under the wing. A lot of people have commented about how nice it flys and how neat looking the color scheme is.
Did I mention that I have two of these airplanes? The other is already covered; all in ultracote and it has the large checks under the wing. I have to install an engine. I have difficulty finding a muffler for it because the cowl is so narrow and I really did not want to alter the smooth lines by cutting holes for the muffler. On my first airplane I used a Tatone "muffler" with hoses to extend the exhaust out of the cowl. It works fine but the "muffler" is nothing but a header so its loud. Sorry, no pics of the engine and muffler at the moment. I'm anxious to see photos of your completed airplane.
