Man, that is looking SHARP! Can't wait to see it in person
Thanks.
Yes, definitely bringing it to NARCON.
It will be a display piece at FlisKits if there is enough space, or in the rocket garden. Also will bring this and the TOGinator to my "Fun with Clusters" presentation Saturday morning.
The Perfectflite altimeter never armed the ejection charge, as the altimeter needs to see at least 160 ft altitude change to do this.
Examination after the flight showed that 7 of 11 motors had fired. With D12's this just wasn't enough total thrust or impulse to get a 6.6 lb rocket up very high.
I had been very careful placing and retaining the igniters, and had expected to fire more motors. 3 of the 4 motors not fired showed signs that the igniter had fired but failed to start the motor, the in the fourth it did not appear the igniter fired.
Next time I will:
1) replace some of the Estes D's with E's
2) use more pyrogen when dipping these igniters
2) load a soon to be available AMW/CTI 24mm F or G reload in the center motor tube
I think if one more motor had fired the altimeter would have armed and the chutes would have deployed. Went with all D motors for the first flight to minimize weight at the back of the rocket and confirm stability. As the rocket proved very stable, slightly more motor weight should not be a problem for future flights.
