Indeed. Will do.
We have probably 8 inches of snow outside (south of Seattle a little way). I am REALLY glad I don't have to commute anymore right now. I will be dealing with some rather heavily damaged old lilacs later in the week, though.

Dang K'Tesh! Another one of those kits I had back in the day that I'll need to get the parts for now and build again!

TJ, save yourself some aggravation and a great deal of time and just get this: http://www.erockets.biz/semroc-flyi...-trident-kv-71/
Laser cut gas passages (and fins), a neat jig to align the various tubes properly, a nice decal set and much more. Just a happy customer who has a good flying Trident from this kit (and a backup kit in my stash).

Jim,
I cut out that pattern and laid it on fins on both of my Tridents (both of which use the Semroc laser cut fins). The cutout fin is 1/32 - 3/64 of an inch all the way around larger. It also doesn't conform to the aft cones on the BT-5s (BNC-5W) very well toward the aft end. Now whether the whole chain that started with that original set of instructions/patterns, through the scanner, to my computer and my printer preserved the dimensions exactly or not is an open question since there isn't a reference length in the scan. It wouldn't hurt if someone out there still has the pattern sheet and could scan it with a ruler. That's really the only way you're going to get the precise size/shape down to the nearest gnat's whisker.....

Thanks Bernard, I may just do that. But I might still want to do an upscale also, just for giggles and $#!t$.

Problem is... Semroc doesn't sell .ork files. I'm trying to sim this in OpenRocket.

Hawk's Hobby at one time made a kit called the "Super Trident" which was BT-60 based, just like their "Super Orbital Transport"

When I was a teen I belonged to a NAR sanctioned club in Ft. Wayne, IN, where I grew up and one of my mentors there up-scaled a Trident then (80's) and a 3x Alien Explorer that shredded fins at liftoff! That was the first I ever really saw any "High Powered" rocketry. I want to say the Alien Explorer launched on a "J", but I can't say definitively.
