R-DAS Flights To date, I have made 2 flights of the R-DAS, both flights carried both the R-DAS and a G-Whiz LC Deluxe Altimeter/Accelerometer, to ensure that the data was accurate (If 2 dis-similar altitude logging pieces of equipment give similar results, then it is less likely that the results are innaccurate) On both flights, the deviation between the altitudes measured by the R-DAS and G-Whiz LC Deluxe, was well within acceptable limits.
