I Actually agree with much of what GHROCKETMAN said on the Estes engine selection, never thought I would ever say that. But the B6-4 and C6-5 are the two top selling engines, so I don't think you will ever see them go away. I believe the contest folks would prefer the longer burning motors then the shorter burning motors, like the B8 or C5 except for maybe the booster motors in some cases.
I built, primed, painted and decaled 6 of the new Mercury Redstone models and flew them on the recommended C6-3 motor and then ALL flew perfect in both calm and windy conditions, so this motor will work perfect for this kit. John Boren |

I think the release will be great for everyone; at any skill level, slant or taste.
Load a D-21 and be done with it! There will be more composite offerings for model rocketeers in the near future. Well done Estes in bring it back!!

I built and flew a Centurn 2" dia. Mercury Redstone that I used in NAR regional contests in the Midwest for year. C6-3's worked perfectly well for the model, particularly if you used a 3/16" rod.
Thanks, Estes, for bringing this one back!

As many MRs as I have built I have never actually read the 1921 instructions. I have built red capsules and black capsules but only today did I get the "if you have a red" or "if you have a black" capsule instructions and the implication upon which you masked when painting. Rather smart really.

I never thought of GuyNoir's idea...upgrade it to 3/16 lugs and rod.
I will give that a try; maybe I will have better luck with a C6-3 then. I'm just of the opinion that the C5-3 does EVERYTHING better than a C6-3. I would rather have that back than the B14.

Seconded, along with a C5-0 for three stage rockets. |

As appealing as a C5-0 sounds, I'm a little concerned about the long tail (of the thrust curve) possibly causing the rocket to slow down too much before the next stage lights. My instincts are the B8-0 might be better for that, providing about the same thrust spike but without the long tail. BTW, I have some C5-0S motors (Centuri) that I picked up a few years ago. I've used one or two of them, but can't recall what rockets I used. Probably an upscale Midget But they were good flights. Doug .

The C5-0S instead of a B14-0/B8-0 works well in the bottom stage of an Astron Farside or Centuri Arrow 300, which are both extremely dicey on a C6-0 unless zero wind with a LONG (at least 4') rod.
Incidentally the first C5-3's (at least first couple years) that Estes marketed under their brand label instead of Centuri, were labeled C5-3S just like the Centuri motors. I think they just changed them to plain C5-3 around '83 or '84.

I have a few still too, and have used them as the first stage on several 3 stage launches. They work fine, better than a C6-0, but not as good as a C11-0. The last time I used one, I used the left-over second stage of a lost Comanche 3 as the first stage of another Comanche 3. It went straight up. There was very little win that day, but I rarely launch multi-stagers in anything but a slight breeze. It was a C5/C6/C6-7 combination. Thanks to a scout who was also a cross country runner, the third stage did get recovered, but he ran over two miles to retrieve it. |

FWIW, the C5-3 was around long enough to get its own igniter plug. The tab on the blue plug read "C5 B8." So we know those two motors had the same nozzle design!
I wonder if the tooling for these motors is still around.
