Nice flight from t' 29mm upscale Duster.  Swapped out t' delay element t' get a 9 second delay.  Nice boost, smooth and straight, arcin' into t' wind at t' top o' t' climb,  Ejection more or less right at apogee, with a good chute deployment.  Fair amount o' drift comin' down, mud landin' on t' field, no damage.  Attmepted t' gather flight data usin' a Jolly Logic Altimete II but t' unit failed t' record for some reason.
