Update on new German motors and the Estes E12


Via TRF:
German model rocket distributor and manufacturer Robert Klima (Raketenmodellbau Klima GmbH) will offer 18mm, 24mm and 29mm in both 70mm and 95mm length.  The propellant is termed "white powder" and is pressed like BP.  One goal is to get full class impulse from the motors (i.e. the 'E' motors will be a full 40 N-s).  The propellant is also reportedly amenable to a wide range of average thrusts.  The assembly line is under construction but an accident in a nearby, unrelated plant, could throw a wrench into the works. [This is the same manufacturer whose motors Quest is planning to distribute.]

Via European Model Rocketry:
This company formally announced their plans at the 2011 Nuremberg Toy Fair. There, they announced:
18 mm: A6-2, A6-4, A10-0. A10-3, B6-0, B6-2, B6-4, B6-6, C6-0, C6-3, C6-5, C6-7, D3-P (long burner), D7-0, D7-3, D7-5
24 mm: C12-x, D18-x, Ex-x

The propellant was called 'composite'.  Production estimates were in the 6mo range [from exactly when is unknown].

My comments:
No body is holding their breath.  Once produced, there is all the import, transportation, and certification requirements.  Sounds more like they will be available in 2013 rather than 2012.

Packed powder typically isn't what we call a composite.  A gum binder in a BP motor doesn't make it composite.  But, this may just be semantics.  Hopefully the packed powder means they can be direct staged. I see 29mm and 'F' motors weren't listed on the European site.

Meanwhile, Estes commented on Facebook regarding the E12's availability: "Not until 2012. Still lots to do once we get this part taken care of."
