Default Possible SLS KIt?

I would like to propose as a future SLS kit the Estes design called the Hi-G Payloader. It is BT-30 based and they recommended Series II motors for payloads (that would be the B14). I attempted to attach a jpg, but couldn't get it reduced to meet the attachment limit.
I am thinking BT225 sized, although I don't know how that would effect the fin layout for laser cutting.

Personal note: I built one of these in high school. I have a picture somewhere. Named it after one of my classmates: Cari-Hi. Hilliard HS Class of 69.

Jeez, I was such a nerd. Am...

Chas

Chas,

Could you give additional information about the origin of the design? Was this a MRN/DOM/EIRP design, or a short-lived production model? I'm not familiar with the model name. Do you have an ID number for it?

The widest part of the fin for an LT-175 2.41X upscale (~30" long) is right at 3". For an LT-225 3.06X upscale (~36+" long) , that same measurement is 4.75". I'm guessing you'd need a compound fin, like on the Semroc Hustler.


Here's a "quick and dirty" workup on the LT-175 version. The colors are garish, but at least you can see the individual pieces.


Cheers,

Jay,

My Hero!

I had run across a photocopy of the plan, but had not had the chance to research it. I have several of the old design books from Estes, including one they gave at NARAM-11. Jay saved me from having to go through them to find the info he provided. Darn, guess I'll spend the time building for NARAM.

Yes, it is 3FNC, but it does have a payload section <g>.

Saturday Night Live psuedo Paul Harvey voice:

"Is Pravda!".

Perhaps we should lay off the rocket fuel, right Jay?

SNL was funny a long time ago.

Anyway, since the Maker Of All Things has a BT-30 and a BT225, why not both kits? Especially the former with a B14-5.
"Stuck it in a tree on a B14. Sorry kid, but we will sell you a replacement. And more B14s..."
