To add insult to injury, our record was broken by nearly 250m.
Is that a typo or is it really almost 50% higher than your record?
No, it\'s not a typo, but it\'s only 42% higher. The Flying I-Beam Kids hit over 800m. I think that the actual number was 849m, but I\'m not certain. They used an Apogee E6. We had 421m on our second flight. They had over twice our altitude. Very sad.

I simply can\'t believe >800 M on an E6. The the weight of the 2 eggs is 120 g and the motor is 48 g. I find it hard to believe the rocket would weigh less than 200 g. To get to 800 M on an E6 at that weight, the Cd has to be less than 0.2! To get to 889 M you need a Cd=0.15! Really?
Your previous 600 M flight on an E15, you present 440 M flight on an E9 and a possible 550 M flight on a C11/E9 are all believable.
I think the > 800 M altitude measurement needs to be looked at.
