New Aerotech E20W revealed!

As posted On their web site and on Facebook, where I found out about it, Aerotech has a new motor out: the E20W. It's a 24mm motor, the same size as Estes C11 and D12 and Aerotech E15 and E30 and 24/40 RMS at 70mm (2.75") long.

Vital Stats:
Impulse: 36 Ns
Burn time: 1.7s
Peak Thrust: 35.6 N
Delays: 4,7
Loaded weight: 49g
Propellant mass: 16.2g
Isp: 233 seconds
Grains: C-slot

It's the same molded one-piece phenolic casing as the F32T and G80T, with the built-in thrust ring and yellow delay holder. It comes in a two-pack, with 2 First Fire Jr. leaded igniters (hooray!), from $19.99. Certification is expected with 2 weeks or so, and shipments to retailer will be with a month.

A promotional flier is here and includes a time-thrust curve.

I'm not sure if it's intended to replace the E15W, or just complement it, but I like it. It's a better design with the new casing, and it's a perfect match for my Nike-Apache. I'll prolly order a 2-pack of E20-4Ws by the end of the year.

Interestingly, available from the same section of their website are thrust curves for two unreleased motors that might come soon: a 54/2560 K375NW Boost-sustain, and a D3-10T with a 5.4 second burn, prolly a single-use motor as no casing is mentioned. I hope they're released soon!
