Well, it is a down size of a sport rocket so I suppose that would be Sport-Scale - just added a Mini Orion from Semroc into the build pool.

Finishing up a Custom Rockets TRISTAR, then moving on to the vintage Estes Battlestar Galactica Laser Torpedo I got from Verna.

Need to throw together a quick and dirty fxed diameter tower launcher tonight..
for a launch tommorow.

For once, I am GLAD Homedepot and Lowes did NOT have some 3/4 tubing..
( I had enough for 2 pieces on hand..it was oversize and rough finish)

So I just got back from a 30 minute trip to a metal supplier.. paid LESS, for much better quality material. I was actually expecting to pay a lot... lucked out I guess.

OK guys,

As excited as I am to see the new Semroc Arcas, SWMBO reminded me that I had gathered parts for a corrected Estes K-26 clone including the Semroc laser-cut fins and mounts. So I decided to whip it together.

Therefore, in keeping with the scale and sport-scale theme of this sub-forum, I'm posting these pictures:

picture 1 is a close-up of the standard Arcas fin assembly, I added the cut out for the mounting screw on the real thing. I also added a thin triple wrap of cardstock for the piston ring at the bottom of the boat-tail. The edges of the fins are sanded and CA'd and they have two coats of balsa filler. A couple of coats of sealer and they'll be ready.

picture 2 shows the whole thing on my old cradle. The body tube is now 20.24 inches long which is the right length according to Peter Alway.

Nike-Tomahawk
Sandia Sandhawk

Coming up:
Black Brant II
WASP
Nike Smoke

All are scratch and I'm trying to do a credible (or at least not laughable) scale build of each one. The one that is closest to completion is the N-T, but I'm shy about posting any pics of my rockets until I've simulated every last screw.

I'm torn over how to proceed with the WASP. My original intent was to build a clone of the FSI kit. That version seems like a pretty nice rocket, but as a scale kit, or even a sport-scale kit, it has some glaring omissions and some not-even-close-to-scale elements, and the claimed scale factor is off by a factor of two. So, do I build it as a clone of the kit, or do I "fix it" and correct all of the scale issues? From what I have been able to tell, FSI actually did a decent job of making their scale kits pretty close to scale, but they really missed the mark in a few places on the WASP. (I haven't really looked at the FSI Javelin in detail yet, but nothing really jumps out as being totally off in it.) The only other issue that has come up with an FSI scale kit was correcting the Nike-Tomahawk's fins and making the fin brackets 3D in the Sandhawk. As a few people may know, I've been working on cloning every one of FSI's kits. (Why? Because I can, and I like them.) The minor details that I have added and corrections that I have made (and all of those that I plan on making) to their other scale kits won't alter the fact that they are clones (and won't need to), but I fear that making the corrections in the WASP will make it into something that FSI never kitted, and hence no longer a clone. Build it clone or build it scale? That's my dilemma.

Also very high up in the queue: Semroc Iris. I am head over heels in love with that kit. The Iris is quite possibly the most beautiful sounding rocket that has ever been built. I may even add the booster! In fact it'll probably be built right after, or more likely concurrent with, the BB II.

That nosecone / fin combination reminds me of like a bishop's hat. What about calling it "The Bishop".

I'm actually going with _______Predator. I have to find a 1st name that isn't being used if I can. Here's what it looks like presently.
