You know tha saying, it ain't what it used to be? Well it is true in the case of the G80T, except that it has gotten a lot better. I launched a 2.1 scratch built that was pretty much identical to a design that I launched 15 years ago on the previous G80 design and my mouth dropped open. You would not think an extra 30ns or so of impulse would make that much of a difference but it did. I timed 7 and a half seconds from burnout to ejection and the rocket was still heading upwards fast enough to swing the tail end up like a pendulum when the chute deployed. Compare this to 15 years ago and even on a truly vertical launch, the rocket was falling back through the contrail by the time the 7 seconds ticked by.
Good job Aerotech.
I will be ordering more.
