Default FSI parts at Quest!

Hello All,

I was just buying some parts on Quest's website when I came across an FSI part--a 21 mm motor mount tube (and also 24 mm and 29 mm motor mount tubes), see: http://www.questaerospace.com/Motor...06_3447168.aspx . They also have 21 mm tubing centering rings for their 25 mm, 30 mm, 35 mm, 40 mm, and 50 mm body tubes (see: http://www.questaerospace.com/Cente...06_3447169.aspx ). Plus, they're again selling their long 13 mm motor-to-18 mm tubing adapter mount (see: http://www.questaerospace.com/index...=3447168&Page=2 ). These are certainly interesting developments...

sorry to disappoint you but those are parts for their 20mm D5-x motors they used to import from China. 21 mm is the outside diameter of the motor tube.

I'm not disappointed at all; I'd rather suspected that that was the case. The parts (especially the motor mount tube) are the correct size for use in FSI rockets (CORRECTION: the 21 mm OD tube should be usable, if cut shorter, as a coupler for the 21 mm ID FSI tubing). I'm more pleased to see that Quest is finally showing signs, however preliminary and tentative, of growth.

They've had those parts for some time. on a positive note I recently ordered some parts from them and the body tubes the sent were like the old MPC ones. Very nice! They also have a new blow molded 30mm nose cone with attachment loop.

Those too are positive signs--thank you for mentioning them! My order today included some 20 mm and 35 mm tubes, and I hope they are of the "MPC fiber body tube" material.

Let us know what you think of them when they arrive. I ordered 20 mm 15 mm and 30 mm and was very impressed with the quality

I shall--thank you for mentioning this improvement in their body tubes! Their 35 mm nose cone, tubing, fin can, and clipped delta fin set would make a nice semi-scale MBDA Sea Ceptor missile (see: http://www.google.com/search?source...1.0.GQRBK6KLrpw ), and that 35 mm nose cone could also be used in a scale Black Arrow, Diamant BP4, or New Glenn satellite launch vehicle (see: http://www.google.com/search?q=blac...1.0.OjNccY5PDVk , http://www.google.com/search?q=Diam...1.0.mwC0653ZPNY , and http://www.google.com/search?q=new+...0.lSw oR6fg9Fs ). In addition:

Quest's parts can be used to make a 35 mm/20 mm Nike-Tomahawk (see: http://www.google.com/search?q=nike...1.0.UfRO4MHj8oA [they have a non-scale 35 mm/20 mm transition, but a scale one would be easy to make with a card stock cone and internal tubing and rings]). For a scale Nike-ASP, Nike-Cajun, or Nike-Apache with the 35 mm Nike first stage, a BT-5 ASP/Cajun/Apache upper stage is only 0.04 mm wider than the correct scale diameter. Plus, all of these Nike-boosted models could have both stages "live," and could use gap-staging (as well as Evan "Buzz" Nau's gap-staged, streamer [or parachute] recovery for the first stage).

Here's a NIke Tomahawk I made from Quest parts based on the AVI Nike Tomahawk.
I don't know if that AVI kit was ever released.

I wouldn't call the cardstock transition "easy", but it can be done.

Thank you for posting this! A duplicate of your card stock interstage, if extended "to a point" and ballasted, could also--if the subtended angles are the same--serve as the 'stubby cone' nose of the prototype Nike-Smoke (the long conical nose of the operational version was found to about double the rocket's altitude due to its lower supersonic drag; both variants are covered in Peter Alway's book "Rockets of the World"), and:

I share your doubts as to whether the AVI Astroport Nike-Tomahawk, which was advertised, ever made it to production as a kit. Today, its Nike-to-Tomahawk interstage (as well as a Nike-to-ASP, Cajun, or Apache interstage) could be 3D printed in different types of plastic, including ABS plastic. Such "after-market, detail parts" could be made by Aerobotix (at Shapeways) and/or by Boyce Aerospace hobbies (I have 3D printed model rockets and rocket parts made by both, which are very good!).

I received the Quest parts order, but the body tubes (T20 and T35) were the regular, white-overwrap kraft paper tubes, which are fine (maybe they're shipping out these to make room for the MPC/AVI-type tubing, or maybe they get their tubes from multiple manufacturers?). What shape is their new 30 mm blow-molded nose cone with the molded-in attachment lug? I didn't see it on their website, but I know that they're still getting all of their parts up on the site (their new motor mount tubes and "new-size" centering rings weren't on it before). Also:

They're now out of the old MPC/AVI/AVI Astroport-type scale Tomahawk plastic fin units (which isn't surprising, since I'd seen them listed as a "Limited Quantity" item on the Quest website for a year or more). "That mold is old" (literally), but cast resin and 3D printed duplicates can be made. They substituted (at no extra charge, even though they cost more) the slip-on, T20-size "Tomahawk-like" fin units that they use in their Starhawk kits.
