I learned to fly with an Avistar ARF last year and wanted to build my 2nd plane from a kit also. I choose the 4* .40. I choose it because if you notice on these forums, you would be hard pressed to find someone who doesn't like it. I also choose it because I liked the looks of the 4* over the Tiger. I spent the winter building the 4* (10 months out of the year it seems) and took my time with it. As a first time builder, I can tell you, the kit was a breeze to build. I just followed the instructions to the letter, and when I got stuck, I got on-line and asked for solutions. After spending the spring flying my Tower Trainer (don't ask about the Avistar, it wasn't pretty) I finnally got the courage to fly my 4* last weekend. I loved it! It's like going from driving a school bus to a motorcycle, but it actually lands sloweer than my trainer. I like the plane so much, I plan on building another after I finish building my slow poke. However, this is only my opinion, so take it for what it's worth. Just do plenty of research before buying your kit to decide which one would suit you best. Good luck
