Nice flight from the 29mm upscale Duster.  Swapped out the delay element to get a 9 second delay.  Nice boost, smooth and straight, arcing into the wind at the top of the climb,  Ejection more or less right at apogee, with a good chute deployment.  Fair amount of drift coming down, mud landing on the field, no damage.  Attmepted to gather flight data using a Jolly Logic Altimete II but the unit failed to record for some reason.
