Today I successfully static tested and flight tested my new 6 grain motor utilizing the new epoxy construction method. I feel comfortable with this design and will use it as the test bed for my payload lofting rocket for autonomous recovery.

You can see liftoff was nice and straight.

And the full burn was strong and slightly progressive. Overall I'm very impressed with the design.

Motor design specifics are as follows:

• I-530 designation, 1.2 second burn
• 1-1/4" PVC casing
• 5 x 2.5" grains, 0.652" bore
• 1 x 4" grain, 0.652" bore
• 7/16" throat, 4.2x expansion
• KN progressive between 300 and 350
• Posterboard inhibitor
• Plastic epoxy construction
