PVC: 27mm OD, 23mm ID, 110mm in length.
First Plug: 20mm of bentonite clay with a 3mm core.
Propellant: 30mm of propellant #2.
Delay: 5mm of delay #7.
Middle Plug: 20mm of bentonite clay with 3mm core.
Ejection: 10mm of ejection #1.
Last Plug: 5mm of bentonite clay.
Changes Made:
- Halved the amount of delay powder and switched back to delay #7.
Results:
All stages ignited successfully, however after all three stages were over, the motor was still burning. Possibly it was just the inside of the PVC tubing. Also, the PVC is still melting too much. It may be a good idea to reduce the amount of propellant and keep everything else the same.
