It seems that Quest is bringing back the Space Clipper DC-Y.

Is that red casing made of paper, phenolic, or plastic?

Thanks for the info about the Nuremberg Toy Fair.

I must admit I'm somewhat disappointed about the delay of the engines coming to market. Lets hope they are avaliable by summer.

It's good to see them using the ILP method, ie. 40E18-P so once we have a ballpark ISP we can know a ballpark propellant mass to determine which will be mailable when approved and which fall into the other hazard classes. It will also make comparisons to existing motors a more direct comparison.

Tbzep, it´s paper. But a very strong and durable one compared to the one Weco used before.

Leo, thanks for mention the other thread. There is even another one which is older than the one you have cited: http://www.oldrocketforum.com/showt...p?t=8299&page=3

Regarding the timeline, my personal opinion was always that it is impossible to start an engine production within a few months. So I guess we won´t see this engines before the end of this year or even later.

Jerry, some figures out of your picture are outdated. Currently Robert plans to manufacture F22-X engines for example. And for what I understand, he talked to Bill to use specifications which fits into US regulatory (e.g. less than 62 g´s).

I got that image from the other thread linked in this one. That thread helpfully has these and other photos of prototypes which at least shows diameters and lengths

18mm 2.75" 20D
24mm 2.75" 40E
24mm 3.75" 60F
29mm 3.75" 75F

The exact thrusts and delays will be subject to certification but it does appear he plans at least two thrust levels in at least one form factor. That is interesting to me.

Also that thread has a photo of a firing which to chemists is revealing. It appears the ISP is around 180. BP is around 80. Around in this case should be interpreted as "up to". They also show thrust curves but not propellant masses. I see the tested total impulse of the prototypes is just over NAR "full" levels, which I consider good news because that shows they are not required by engineering limitations to make "cheater" motors.

It is really nice to see these guys and CTI and USR all using the I Leading Power method. It helps to see of you have a "full D" or not (or whatever). Besides being important in contests, it is also important for heavy rockets to know if you are flying with an Estes 16.2 D 12-3 or an AT 20 D 21-4 so you can have the safest and most reliable flight possible.

Wouldn't it be great if USPS mailability were increased to the FAA exempt 125g level? They're both Federal agencies. Propellant is NOT an explosive. It is a slow burning solid, gents. Established in a Federal lawsuit applicable to all agencies.
