Second, and day-endin' flight o' me T' Launch Pad AGM-88 HARM on an Estes E9-4 engine. Note that this bird flew earlier on an Estes D12-3 quite nicely - straight boost, me hearties, and only arced over well after t' propellant had burned out. Begad! Ejection was excellent. It is puzzlin' about t' E-motor failure with one possible, crucial difference bein' t' length and weight difference betwixt D and E motors. Avast, me proud beauty! This may have moved t' CP in back o' t' CG, ya bilge rat, resultin' in instability.
