I just recieved my Frog Log book after a recommendation from a friend. I like they way the log book is laid out. Much like the RV-10 that I built you can customize the log book by selecting the color and logo. it is nice to be able to have your airframe, engine, prop, and avionics log book all in one spot. I had several people ask me where I got it at. Here is the link. http://www.froglogs.com
