    One of the early Payload models in first fleet they Centuri Kc-20 Payloader-II was alway a great little 18mm motor workhorse. I used it often at Grade and Middle school flight demos showing youngsters some of the neat things that could be flown (other then animals and insects). Night lighting, acceleration graph/carbon paper plots, Locator buzzers...etc.
    My little 2.6X, T3(.375") diameter downscale won't quite allow the same experiments but does in fact have room for a single LED night flying fixture.
    At an Empty weight of 7.9grams with it's 1"x 15" Red Teflon streamer it comes back slowly from nice 100foot plus flights.

    Love to have the Original Centuri version. Got a little rushed for time on this one; flaws and so forth, but really dig the look of it.

    I've always liked that rocket. Of course, I'm a Centuri fan and there weren't too many designs they produced that I didn't like. Nice job and I hope it flies well for you.

    John, this thread is lost—as are several others from the Centuri Gallery.

    This is the Estes Payloader II with a cut-down payload section and a Semroc nose cone to make it more closely resemble the original Centuri version. The only thing that is off is the diameter of the body tube. The original Centuri ST-10 tube was slightly larger.

    Here's my latest, it was on my build list for years.

    Payloader II A.jpg

    Payloader II C.jpg Payloader II B.jpg

    The BT-50 tube was replaced with a heavy walled BT-50.
    The nose cone was a BMS replacement, it is closer to the original Centuri shape.
    I drew up the Centuri logo and name decal.
    The red paint is Rusto Metallic.

    The entire build is here:

    I am in the planning stages of building an upscale model of the 1970 Centuri Payloader ii, which was my first rocket. That rocket was donated to the universe after a couple of flights when it sailed away in an stout Oklahoma "breeze". I have read all the information I could find on the Centuri Payloader ii and am still wrestling with a question or two about the rocket (finding the 1970 Centuri Christmas Catalog on the Ninfinger link brought back many found memories). The 1970 rocket is listed as 18.5 inches tall.

    The problem with that is, none of the variables of nose cone sizes or payload tube lengths sum to 18.5 inches, when you add in 1/4 to 5/16ths of an inch of height added by the fins extending below the body tube. The 4.5 inch nose cone (plastic), the 3.5 inch payload and 10.5 inch body tube equal 18.5 inches but, surely Centuri didn't determine the rocket height sans the fins.

    As this post has not been updated in a few years, I was wondering if anyone had come across the specs of the Centuri Payloader ii since it this thread was started.
