It is a bit of stuffing around, but an accurate doppler reading should easily beat a cheapie GPS for speed accuracy on short runs... and he's also getting the RPM to boot.
Thinking about it for a sec, most of the stuffing around has to do with downloading files, putting them into Audacity, etc. Would be a heck of a lot easier if you just had an app on your phone that did that for you on the flight line Jason...
Turns out there is one: http://www.rcspeedo.info/ Think there's a free cut-down version too if you wanted to check accuracy first.
Doesn't appear to do RPM at a quick glance though, but if this approach proves to be useful you might just know someone you might be able to talk into writing up a custom app
