Hi Folks, I wanted to mention again that I created a custom iOS app called "RCcoPilot" for the Apple platform. You can read about the app here:

www.rccopilot.com

If you search the Apple App Store, you'll find the app or go here:

The app was custom designed by me and specifically was created to allow for tracking flight times of my models (supports up to 100 models), including custom pictures of your models, information, and also the key part - I am an electric flyer so I have a segment of the app devoted to tracking LiPo battery packs & performance (ie Battery Log). There is an audible timer that allows you to land before battery (or fuel) runs out, no more dead-stick landings... and it supports Social Media announcements and tracking of up to three (3) of your favorite flying fields - complete with Long/Lat coordinate tracking so you can find remote fields that have no street address! Finally, there are a ton of R/C specific tools I developed. For $1.99 it's a pretty good value if I do say so myself... thanks for reading. If you have any questions, let me know!! (currently only iOS, considering porting to Android - if the demand is there)
