Probably to encourage us to buy Quest-sized tubes.
Any one seen any of the new Quest D's? Why did they make them 20mm instead of 18 or 24?

Ironically, Quest does not have a tube to fit it...
Good! More for me...!How weird. I won't be stocking up on those
But after receiving my order from the Pres-day-sale, I have to confess that I opened one of my new D motors to fondle it a little bit. (I know, TMI)
I am impressed that the rolled motor case appears to be high quality, and even the cuts at the end of the case are neat and clean (better quality cuts than I have often seen on many motors from a certain Penrose manufacturer).
Nozzle materials also seem impressive. The nozzles are a uniform grey/gray/whatever and seem to be made from a clay that was very finely powdered. No perceptible grit or roughness, no visible "crystal" patterns, very shiny smooth faces and sharply defined corners, very high levels of manufacturing craftsmanship (do those two even go together?). No significant nozzle-induced swell in the aft end of the case on the examples I checked.
The thing that surprised me was that the paper label is almost sloppily applied, by comparison with the rest of the motor. The loose label makes the whole thing look more like a firework toy purchased from a roadside stand. I am a little concerned if removing part/all of the label will fall into the category of "tampering" because it sure looks like a bunch of label will be scraped off when inserting these into a motormount. Label craftsmanship is definitely inconsistent with the rest of the motor.
I'm just itching to try sleeving one of these to fit a 24mm mount, and hear 4+ seconds of loud (load?) thrust!

I'll be flying at least one D5 on Sunday!![]()

They're very similar. However, IIRC, the E5 had a larger initial thrust spike for lofting larger models.I'd like to hear one of these new D motors. An old favorite was the FSI E5 Steaming Tea Kettle motor. I had a special rocket for these and even when K's ands L's and M's were going off for some reason people stopped and watched those flights![]()
Steaming Tea Kettle, huh? This I have to hear. I just bought a dozen of these motors and I can't wait to try them out. Did the "tea kettle" sound include the whistle?

I was able to fly one D5-4 motor at the SCRA launch in Los Angeles today/Sunday.
Rocket used was an Estes Eliminator kit.
I made a 20mm/24mm motor adapter by taking an used D12 case, knocking out the clay nozzle and peeling the inside of the casing.
Weight of the Eliminator with D5 motor was 6.1oz.
There was little/no wind when the rocket launched. That D5 seemed to burn forever.
The parachute deployed and the rocket was recovered undamaged.
Next time, I will use a lighter weight rocket.![]()
