Quest Composite Motors
 
I see on the eRockets site, Quest 18mm composite motors (Q-Jet). Currently out-of-stock.

Were they ever IN stock? I don't recall ever seeing one..........

I think it's more like they soon will be in stock, or at least are expected/hoped. Nice prices. I can order mine the day before a launch and pick them up at eRockets. I feel like a fortunate son for a change. :rolleyes:

Interesting. Thatís the same price as local mass marketers are selling the Estes As and Bs for in two packs.

Also interesting that they are certified by Tripoli and not NAR.

In any event itís a sign that they will soon see the light of day. I like it.

I gotta ask this one....WHY would anyone want to pay $8.99 ($4.50 each) for two little composite B-motors ? Just for the novelty of they are composite ?
I guess I understand the B4-6 as that is no longer available from Estes.

I'm not paying $4/each for A motors or $4.50/each for B motors EVERRRRRRRRR.
You can get a 3-pak of Estes B motors at Hobby Lobby for about $6 ($2/each) when using the coupon.
I go there and pick up blast-off flight paks really cheap.

No Hobby Lobby Iíve ever been in has Blast Off packs....or Iíd be all over that idea. They just have bulk A8-3s. I have an adequate supply for several years I think.

As for the Quest motors - in the listing on the Quest site for B4s there is an image of an instruction sheet with data about A, B, C and baby D motors including masses and thrust curves.

Those C8s look interesting, and the D12s could be thought of as Cs with a little something extra.....

This is interesting stuff to see as Iím sitting in the dining room of the hotel where NARCON begins this afternoon. I will have to see what I can glean from the vendorís forum this evening.

(Roger and Bracha Smith from jonrocket.com are at the next table over and I came down in the elevator with Tim vanMilligan, so folks are beginning to turn up. I havenít seen the Estesí yet.)

The C8's could be interesting if they are a true 10n-sec as we all know Estes C's are only about 8n-sec. The C8 also has the high initial thrust profile of the old C5-3
The 13n-sec 18mm D12's would be great; it would effectively replace the great but LONG OOP 18mm Cox D that was about 12n-sec. Just right for something needing more than a full-C, but not needing/wanting a 20-nsec Aerotech 18mm D.
That 18mm D12 sounds like it would be a great motor for the Estes 1284 full-stack Space Shuttle and the Estes/Semroc Mars Lander.

Well, that is a bit of an unfair comparison. The $8.99 Quest price is full retail while the Hobby Lobby Estes price is steeply discounted. More accurate would be $4.50 per motor Quest FRP versus $3.60 per motor Estes FRP.

Still, I agree the A and B composites don't appear to offer a compelling price point for their performance. I'm much more interested to see the C8 and D12 composites when they come out.

It will also be interesting to see if anyone is able to sell the Quest composites at a significant discount like AC Supply and other vendors do with Estes motors.

According to Gary, they can be ordered from the Quest site tonight. Whether they sent an advance shipment to eRockets is not known.
