You know the real difference between Semroc and Estes.
Semroc asks us to vote for what we want released . . . Estes tells us what they'll release. Which company is really listening to their customers?! I still firmly stand behind my thoughts about 2009 Estes releases, based on their previous promises that they never filled. They've promised lots and have yet to fill on many - why should I believe them now? |

Well....my own two cents. I think it's great that Estes announced this. I think it will be even greater if they come through and actually market them. If they do market them, great. I think I'll buy a few (okay, maybe a little more than a few... ) If they don't, it's no skin off my nose. I still have all those other vendors out there willing to provide for me. I'm not changing anything I do or where I shop.

It has been important to us from the beginning to not substitute off-size parts. An ST-7 tube is different from a BT-20. It is 69% thicker and the ID is has an extra .005", so a "bulged" engine will usually fit in an ST-7 when it will not fit in a BT-20. The walls are three wraps of paper instead of two, so they are much stronger. Many of our friends have original nose cones or body tubes from the early days. If they have an old BC-103 nose cone, they expect an ST-10 tube, not a BT-50 which is "close", but their nose cone will just fall through. A BT-55 is very close to a BT-56 (ST-13), but we have to stock both, because they are not interchangeable. When we first started, we were going to try to "fool" our friends by using tubes that were close enough, but we have fixed all of those now (except the Sky Hook which is due.) Our first release of the Space Plane used the ST-7 instead of the BT-30 like the original did. The OD was only .008" smaller using the ST-7, but we have changed it recently to the BT-30. We had complaints that the earlier version using the ST-7 had cases where the engines did not eject quickly enough and blew the Space Planes apart. Imagine if we had used the BT-20 with walls only 60% as thick and a much tighter engine fit! I think our friends are discerning enough that we could not substitute sizes just to keep our inventory down at their expense.

Carl,
I appreciate your efforts to keep the dimensions on your products as close to the original as possible. Semroc has great products and customer service! Now, only if my wallet felt the same way. Keep up the good work. Bob |

I was updating the Classics pages when you saw that. I was marking them as Estes produced. The celebration was for Walt Cunningham. Sorry we had to be so secretive about it, but Dot did not want him finding out the surprise aspects of it. Semroc is not in any type of agreement with Estes Industries. Our friendship with Vern and Gleda would preclude that. Besides, the cost of balsa nose cones would be prohibitive for them with the quality level that is expected of us.

New Estes releases
I am sorry for all the posts, but I have been away for a while.
It is good news for the hobby that Estes Industries realizes that balsa is good and the old designs from Centuri are great! That is what we have been saying for years. They are listening. The most important thing they announced is that they have realized that "Made in the USA" is coming back in style. What a great time to start keeping the money and jobs here, among friends. Very encouraging.
