I totally agree that the angled Centuri Deflector was much better than the Estes flat-plate.
Estes should have changed theirs to match the Centuri design. FAR better at keeping "blast debris" off the tail of rocket. The Estes design only served to protect the PAD, not the rocket. It actually deflects the blast back UP at the ROCKET.

Estes had an angled deflector sold as an accessory in the 70's, but it wasn't as fancy. The Centuri version should have been added as an accessory when the two companies products started crossing over.

I remember hearing 'reading' that Estes had acquired some (if not all) of MMI's inventory. That curved deflector looks to be same one included in the MMI Arcon kit. In the 2nd 1961 Estes catalog a complete MMI style launch pad was offered, at least it looks like one. |

I remember being mystified by references to the BT-40 in Estes literature I read in the early 70s. How could a whole body tube GO AWAY?
Later read all about it in scanned catalogs. The BT-40 was convolute-wound, like the BT-30. There was another, shorter plastic cone available for it, as well as balsa cones, bulkheads, and payload sections. VERY early catalogs referred to BT-1, BT-2, and BT-3. I don't recall the mapping.

My guess would be that the short plastic cones were (like the fin cans) firework components.
Vern or Gleda might remember, but we're getting into micro-history here. I remain bummed that firework fin cans of the spin-fin and Dirty Bird variety are no longer around. I've seen new ones, but they look "wrong." Oddly angled.

I don't recall hearing that Vern Estes was in the fireworks business. He owned a construction business. Orville Carlisle, who sent the first motors and models to Stine, was into fireworks.
