Sold tail cone closures for AT 98mm motors

[DeeRoc29]

There has been enough interest to justify another run of custom aft tail cone closures that fit AT 98mm motors. These are perfect for that minimum diameter M2500, N1000, or N2000 project you've got. These closures will function like a standard aft closure in every way, but with the benefit of a tail cone to reduce base drag and increase your rocket's performance. There are two types of 98mm closures, one for the large nozzle (N2000 or M2500T) and one for the standard nozzle (M1939 or N1000).

Specs for large nozzle closure:
- precision machined from 6061-T6 aluminum
- 3.16" total length
- 2.40" exposed tail cone length
- 3.98" max diameter at shoulder
- 3.02" diameter at aft end
- slide over large single-throat AT nozzles
- aluminum finish, not anodized

Specs for standard nozzle closure:
- precision machined from 6061-T6 aluminum
- 2.04" total length
- 1.25" exposed tail cone length
- 3.98" max diameter at shoulder
- 3.18" diameter at aft end
- aluminum finish, not anodized

These are not certified at this time and are for research flights only. I am offering the large nozzle closure for $185 and the standard nozzle closure for $175 each, plus $10 shipping to anywhere in the lower 48. PM with interest. Orders will be taken through May 1. Turnaround time is 4-6 weeks. They will be shipped via USPS priority mail.

They look great behind those Binder Design fin cans.
