1/12 scale test flight 2 was nearly perfect! Video link below.
Improvements over test flight 1 included:
- A new model was printed in short order with adjustments to accommodate a 1010 rail for launch guidance.
- 8x D16-4FJ motors all with the same batch number
- ignitor resistance was measured, paired by similar measurements, with pairs spilt on opposite sides of the model
- designed and build high current ignition relay box (details below)
- flown in lite winds

Components were installed in a 3D printed box:

On to the flight, we proved the model is stable! Ignition had a slight delay left to right, but the 1010 rail kept the model vertical. Motor burnout was also not equal, but the model righted itself to the flight path!
The video you have been waiting for:
Dragon test flight 2
Landing success for the proof of concept not a high priority for this test flight. There was a successful recovery, but despite a near perfect ejection timing from the D16-4 motors, the parachute did not deploy until the very last possible movement.

We still have a lot to do on the 1/6th scale version to fly at NSL West. Good news though, we're feeling confident in the stability of this odd-rock and have learned a lot in these test flights.
