The use of the word engine while not technically correct is valid simply because they have been calling them that for several decade and changing the term completely would possibly be confusing to low information users. The fact they adopted the term motor at all over the past several years is a step forward to rhetorical accuracy. The morph of the product line to increasingly duplicative designs differentiated only by colors, is an interesting inventory control development. The "fantasy" rockets on the cover are a wink to the "good old days" whether or not they actually sell. The thing I take away from this catalog is just how indestructible certain rockets are. Alpha, Alpha III, Maxi-Alpha, Big Bertha, Wizard, Viking, Yankee, etc. Some rockets simply have a steady following over the course of decades! The A10-PT is the rocket car motor I presume. That back cover has the distinct flavor of future vaporware.. Jerry |

That kit disappeared off the Estes site in July. You can still find it at several other web sellers though. |

In fact, isn't 2015 the 50th anniversary of the K-23 Big Bertha kit?

I am still surprised the Super Alpha did not sell better. BT-60 is the most practical size for this design. Maybe it is the "wrong" nose cone after Estes went back to plastic. Maybe it should have had a 24mm motor mount instead of 18mm. Bill

ANYTHING BT-60 and above should have a 24mm mount standard.
Include an 18mm adapter.

You could also use a short piece of BT-5 or BT-20, say 1/4"+. "Slide Ring" Tech Jerry also cite: https://www.google.com/search?q=sli...hute+slide+ring Last edited by Jerry Irvine : 01-14-2015 at 06:36 AM. |
