Check this out, very small. I use it in my boats.

Think this is the same as the velocity (link in post #3) but much cheaper from HK http://www.hobbyking.com/hobbyking/s...ta_Logger.html

Yep, those are also good. My deal is I want one that has the batteries as part of the unit so there is nothing at all to hook up. Most of my receivers are in traxxas waterproof containers so I cannot plug it in for power. I have never seen the one that Foamaholic found, pretty cool.

Just checked the Foamholic solution and found this message:
The SkyTraceGPS is currently out of production due to a parts shortage.

Yikes. Didn't know they were out. Should have checked.
