Here's a picture of the three new kits which were just announced.
The Super Big Bertha is in a bag but the kit is changing to a box when it becomes available. The change was required because the body tubes were getting damaged during shipment.

I like all three.
It's too bad I am forced to sell many of my items in my collection right now. I've missed out on many of new releases the past few years. Including many of the "Classic Series". Maybe if life ever starts treating me good again I will be able to buy some off Ebay and over pay just to have some to build and fly. Such as life. |

The Astron explorer has too many nose cones. The Bertha deserves a box. |

[QUOTE=Jerry Irvine]While on this topic why don't they have a 29mm Blender kit? Why pay less for power?[QUOTE]
29mm Blender = awesome g80 flights! 38mm Quinstar = more awesomer.

BT-56 is just Estes' name for ST-13 BT-52 is a slip fit of BT-50 and it was used for the Thor Agena. 96 (thor diam.) / 60 (agena diam.) = 1.637 (bt-60 diam.) / 1.024 (bt-52 diam. + 0.01 -- I wonder if that wasn't an off-by-one error originally when specifying to the tube manufacturer?)

A shorter piece of BT-52 was also used in the K-39 Saturn V.

I wonder if BT-52 is Centuri ST-10?

Another thing to consider is that ST-10 has a wall thickness of 0.020", and the equivalent dimension on the BT-52 is 0.013". The Centuri tube has an extra layer of paper in it, so ST-10 is a bit sturdier than BT-52.
