Today the project suffered a setback in the form of a catastrophic motor failure shortly into flight that resulted in rapid disassembly of the fin can.

The motor forward bulkhead failed at the glue bond line. Likely due to ineffective bonding. This was the first failure of this type in some 35 static tests, and not expected to happen again.

To limit the chance of a failure, multiple motors of the same design were constructed and tested prior to launch. To limit failure in the future a better bonding agent will be utilized.

As a plus I did successfully test my single skin parafoil at the beach. I'm going to be doing some additional bridal adjustments, but so far I'm pleased.

Looks like I'll be able to get 15-20 mph of wind penetration with a wing loading of 6-8lbs. Quite acceptable.
