I've built the 40 and the 60. They are great sport planes; dunno about being pattern-capable.

Several things that I would pay close attention to during the build:

1. Take the time to get the wing leading edge properly shaped. It DOES make a difference in how the model handles at low speeds. I made a template from the wing side view and took my time sanding to get it uniform all the way out.

2. This design has a bad habit of nosing over while taxiing if built stock. Do what you have to do to get the main gear axles directly under the leading edge; I fabricated slightly longer gear struts (to maintain prop clearance) and bent them forward a bit. If you plan to use wheel pants, adding a rear brace to each strut is a good idea. This prevents the strut from flexing back on a hard landing and allowing the rear of the pant to punch a hole in the wing.

3. Use 1/32 ply triplers on the wing rib cut-outs that hold the main gear blocks. Doublers are provided, but a hard landing can fracture this area, which is a major PITA to repair once it happens.

There is quite a bit of shaping/sanding on this model, but that's why we build, eh? Take your time on the nose and fair it all in to the spinner ring; it looks quite racy if done correctly.

One last thought; I would replace the supplied tail wheel assembly with one that bolts to the bottom of the fuse and is attached to the rudder with springs or rubber bands. The supplied unit glues directly into the rudder and is a beach to replace if/when it breaks.
