Kitlog pro
I also Love Kitlog Pro. I've seen just about all ways of keeping the logs for building. I know HTML, I use Microsoft Excel.... Kitlog Pro gives you many additional features that would be cumbersome with other tools. First of all you get many tools built in like Maintenance, Reaserch and resourses (Advisory Circulars, FAA Regs), Inspections, keeping track of first flight info and thats on top of the Builders Log which IMHO Top notch. The functionality for logging each project is very Customizable in that you can add any catagory for any step of the project. I spend about 15 Minutes each night after building. I upload my pictures to my PC, fill in a few words of process, log the pictures and that's it. I also upload Mykitlog to their webpage. This accomplishes two things, One, it give others a chance to see my build and Two, off site storage for backup, all included in the price. Did I say it was easy to use? Yes very easy.
