Yes Gary Rosenfield started and is the owner or Aerotech. He also started Rosenfield consulting services (RCS) maybe 10 years ago to service the research community. <br><br>If you’ve flown Aerotech motors, you have used RCS stuff. I think the disclaimer is meant to say that the commercial hardware does not have the wall thickness needed if you are making very aggressive propellants. It seems to hold up just fine with aggressive AT reloads, but generally people doing research use thicker walled cases like Loki, AMW, and Mostly Missiles. In my experience this is what I’ve seen. <br><br>Bob<br><div class="gmail_quote"><div dir="ltr">On Sat, Jun 2, 2018 at 7:15 AM David Bloom <<a href="mailto:dwskb@att.net">dwskb@att.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Yes.

Correct me<br>
if I'm wrong, but isn't Aerotech the<br>
"hobby" arm of RCS?<br>
