Sky Hook with BT-30?
It appears this old Sky Hook kit has a parallel wound BT-30 tube in it.
https://www.ebay.com/itm/Vintage-Es...IP/302698663555 Was that a thing? [EDIT] Looks like the same thing in this Mark kit: https://www.ebay.com/itm/Vintage-Es...IP/302698665366 |
Yes I believe they were both BT-30-based kits. I happen to have a 1969 catalog laying here by the computer and the entries for both give an OD of 0.769 which is BT-30.

Hmmm, that reminds me, it's about time I treed another Sky Hook. Guess I'd better stick one in with my next eRockets order. :( :rolleyes:
|
Yes, BT-30 along with the Astron Scout, Sprite, and Space Plane. Maybe more, but that's all I recall.
|
I believe that the Sky Hook started out as a BT30 kit, but later changed to BT20.
The other mentioned kits (Scout, Mark II, Sprite, and Space Plane) stayed BT30 throughout their entire run. The Scout II was BT20 based. |
I think the original Hornet as well.
|
I checked. The Hornet was correct, and one I forgot as well. The Astron Mark. John's list also includes the Scout ll.

I just finished my first ever Sky Hook, the Semroc “Ready to Build” version, called the Sky Hook II. These are nice little kits. The 1” body tube is a slip fit over a motor tube. So the fins have a tab that fits in main tube slots, gluing them to the motor tube. The Sky Hook II has been discontinued, but a few other nice models are still available, like the Cherokee-C and the Mini Omega.
I’m not sure why I never built an a Estes Sky Hook. I guess something else always got my rocket dollars when it was time to place an order. I love the fin shape, such a classic design. I bought an Estes PSII Panavia, and plan to cut new fins to turn it into a Super Sky Hook. Correction: This RTB kit has an ST-7 motor tube centered with rings in an ST-9, which is a slip fit in the ST-10 body tube. Fins are tabbed and the fin tab glues to the ST-9. |

Yes, all BT-30's were parallel wound until the 70's. The initial ones were apparently made on the Estes' kitchen floor (or maybe table) with manilla folders. I think they quickly got a tube company to make them with the manilla material, but they still looked hand wound! I have a couple right here. Maybe 1973 was the first spiral-wound BT30 I ever saw? I think the Mark II was the first kit utilizing the spiral-wound tubes. |
