    I'm in Canada, so I emailed them. About 15 minutes later they replied that one will be on its way! Estes customer service is excellent.

    The kit diameters are now all listed on the Estes website.

    The Doorknob is 3" diameter.

    Doorknob isn't that a LOC kit?

    Doorknob 1&2 were sounding rockets used to gather data after nuclear bomb tests in the South Pacific. LOC has a 7.5 inch semi-scale version.

    It shows up on the Coming Soon page, you can sign up for an email notification when it is in stock on the product page.

    Does not appear to have enough wing area to convert to an actual rear-eject glider, you know like the SkyDart, but you can always add more wing area...hmm...might be too heavy though. Looks like a great kit to build stock in any case.

    My info says that the LEO Space Train is due to be released at the end of January this year, or early Feb. That is an approximate, but should be very close.

    I did notice the Mini-Max was gone. May have been for a while; I haven't looked at a catalog in some time.

    Given how fragile it is I suspect they felt it could do more harm to their rep than good. Still haven't flown mine. Also suspect the size of the market for that particular kit, compared to the cost of producing it, made it less viable as a continued production item. Still....I'm glad I got one. I was hoping to see a Merc/Atlas or a Saturn 1B this year but... there's always next year.

    Last catalog appearance for the Mini Max was 2016 - though there was no 2017 catalog. It’s been out of stock/discontinued for awhile - maybe six - eight months ago?

    Hi, Andrew !

    I just exchanged several emails with John Boren. Apparently, many people are unhappy that the diameters were not listed. However, the data is available on the Estes website and, hopefully, will be included in the 2021 catalog.

    DOORKNOB :

    https://estesrockets.com/product/009720-pro-series-ii-doorknob

    Recommended Engines
    E16-4, F15-6

    Projected Max Altitude
    1100 ft. (335 m)

    Recovery System
    24 in. (61 cm) Parachute

    Length
    26.9 in. (68.3 cm)

    Diameter
    3 in. (76 mm)

    Estimated Weight
    10 oz. (283.5 g)

    Age Recommendation
    Estes model rocketry is recommended for boys and girls ages 10+ with adult supervision for those under 12, and rocketeers of all ages.

    FYI - The current NAR Motor List does not show the C5 motors yet.

    Since you asked . . . According to Estes : C5 versus C6

    You're welcome !

    Frankly, I question the burn time on the C5 . . . I believe it would have to be shorter than the C6 burn, but I could be mistaken.

    Yeah, I looked at their specs in regards to burn time, avg thrust, peak thrust, propellant weight, and total impulse. Something doesn’t add up in the specs unless they are using two different formulas of black powder in the same motor. I highly doubt that. Even if they were, it didn’t add up mathematically. I suspect a misprint in the specs somewhere. I think we’ll see the truth when the motor is tested and verified.

    Agreed . . . Once we get the "real world numbers", then we'll know.

    At this point, it's officially unknown, but I agree with your logic.

    The c5 curve looks right and is probably correct -- the legacy c6 designation if certed today would be c4.7, assuming they didn't want to round it for obvious reasons.

    The C-11: -0, -3, -5, and -7 are listed on the engine chart, pg 70, of the 2020 Estes catalog so I’d say it’s a safe assumption it’s back in production. Hope so, one of my favorites bigger rockets.

    Also AC Supply has the C11-3 bulk packs listed. I figure these are companions to the Green Eggs bulk kit pack.
