    This thing is way tooooo big. I saw the CR-3 number and thought I was ordering the smaller computer. This one is too big, bulky. I used the smaller one for 25 years and I love it, just can not find one. Believe it, my cocker spaniel chewed my old one up.

    The product was recommended to me by someone who had a CR-2. I was incredibly disappointed that it came without an instruction booklet. Yes, there is one on line but that is not the same as the booklet the guy had who recommneded it to me. It was going to be fun to get back in touch with my early years of flying. Instead I have to spend my own paper and time creating a book i thought came with this product. Disappointed.

    This beats an E6B all to heck. Especially as an engineer/math major I don't need the wind graph, just need to remember the cosine of angles.

    A lot of stuff in a compact package. Seems well made and durable.

    Cons

    Does not ship with a manual. Manual is on line but not in text form. Quality of page images is poor and it's virtually impossible to print it as a booklet.

    General Comments

    If you don't need a manual and fly jets it haseverything you need.

    Looks like it should last, scales/information are clear and easy to read.

    Cons

    Documentation weak.

    General Comments

    Included documentation (downloadable manual) is barely adequate. Much function parallels an E6B, so if you're used to that, you can be functional immediately.

    Added functionality would be easier to use with better documentaiton. (I'm a technical writer, so this sort of thing gets my attention.)

    Pros

    Best flight computer out there. Just as easy to use as a E6-B once you learn. Highly reccommend the workbook/ manual with this purchase. The CR is capable of multiple functions the E-6B is not related to high speed/ flight level flying.

    Cons

    Cost. It's a plastic disk.

    General Comments

    If you're a pro you need one and need to know how to use it
