I have used both of these. The first is a log book a guy produced just for RC on ebay. Here is his email address so you can send him a note to see if he has any listed. I had to contact him to place some on ebay so I could buy.

I found another RC log that fit my needs better. It requires Microsoft Access databse program, however, the application is free. This is a great way to track everything RC and it is called Flight Log. Here is the website.
