Brief:
This is a comparison review of Aerotechs new G79W, including the new
29/120 RMS case.
Construction:
Although this product was introduced at LDRS 23 in July 2004, my casing (S/N 037) has a manufacturing date of 1/8/02. This product was obviously in the works for a while. The case is new and is not interchangeable with the 29/40-120, but the closures are the same as those used with the 29mm high power cases.
The reload kit is a typical AT reload so I won't go into the details--liners, insulators, O-rings, two slugs, etc. Here is a comparison between the G79 and the G80:
G79 ¹ | G80 ² | |
Type | RMS | SU |
Total Impulse (N-sec) | 115 | 120 |
Burn Time (sec) | 1.5 | 1.5 |
Propellant Weight (g) | 58.6 | 57.4 |
Propellant Type | White Lightning | Blue Thunder |
Delays (sec) | 6, 10, 14 | 4, 7, 10 |
Igniter | First Fire | Copperhead |
Loaded Weight (g) | 158 | 120 |
Length (in) | 5.9 | 4.88 |
Retail (as of 07/20/04) | $11.95 | $18.95 |
Notes: ¹ per AT. ² per NAR. |
The main trade-offs include:

Flight:
I have flown this twice...and I like it. Lots of white smoke like my beloved
G80FWLs. I do have two observations:
I will monitor The Rocketry Forum to see what other peoples experiences are.
Flight Rating: 4 out of 5
Summary:
I am ecstatic about this product release. I love G80s and the G79 is a lot
cheaper. (Not as cheap as $10 G80-FWLs from Magnum, but those days are gone for
good.) In more good news, AT has promised Redline loads soon. (I though I saw
Blue Thunder reloads too, but cannot find the reference.)
