Coming Estes Kits
 
https://www.estesrockets.com/coming-soon/

Three new kits on the website. The Astron Explorer is Skill Level 4 and appears to be a ducted ejection like the Trident based on the BT-55.

Super Big Bertha re-released for 29mm BP motors with laminated fins.

Could be interesting.

I don't see slots in the Super Big Bertha toobs. Cut your own?

I suppose you'd have to. There are clearly tabs on the fins (in the pic of the parts layout).

To be clear, I 'm buying anyway...

Gee, we ought to ask John (JumpJet) about those fin tabs. I would have expected the production kits to have the slots cut. The “bag of parts” that I got from him at NSL required me to cut the slots but I thought he told me that they’d be cut in the released kit....

The website actually says that one is skill level 3, which is a bit surprising if you have to cut the ducts yourself (it appears as if you do indeed).

It's an interesting looking kit, especially with the nose cone in the middle of the main BT.

Yup.

I contacted Estes about that question.

The response was, "...We planned to have slots cut in the tubes but it's a long story..."

A cutting guide is included and the kit will come in a box.

True, but it says "4" twice in the kit description. I was surprised that it includes a baffle and alignment fixture (like the SEMROC Trident kit). John Boren is really bringing it. He designs using the currently available Estes parts, but my first thought was "SPEV?"

Ah..... another one of those. I managed to cut the slots pretty easily using the paper guide that John included in the parts bag at NSL, so it certainly isn't a deal-breaker.

I've flown the one I have in primer twice, both on E16-6s. It gets to not quite 600 feet that way.
