Streamers tend to be much more forgiving compared with chutes, plus low power boosters usually don’t need THAT much recovery help. Often as long as they don’t go ballistic (which IS a problem with long gap stages), they will tumble recover fine.
Camanchee 3 boosters are so small that the only real reason to add streamers, and it's a very good reason, is as locator flags.
So i glued all the fins on yesterday with the estes fin alignment guide and let me tell you this. Dont ever ever everrrrr get the estes fin alignment guide!
I've used my Estes fin jig on every build that I can, and I fret over those I can't. My results with the jig have always been very good.
Don't you need 2 guides in order for the fins to be vertically straight?
Keeping the fins evenly spaced is indexing. Keeping the root edges parallel to the tube axis and keeping the cords normal to the tube surface are alignment. (I suppose there are separate terms like axial alignment and radial alignment for those, respectively.) So yes, things like the Qualman guides give you indexing and radial alignment but not axial alignment unless you use two of them. And then you need to assure that the two are aligned with one another or all you'll get is fins that are all off vertical by the same amount (which is fine if you want a spinner). Something like the guillotine jig Apogee sells gives you radial and axial alignment, but not indexing.
The nice thing about the Estes jig is that it gives all three at once in a very simple, easy to use tool. Unless you get one with warped parts, or some such.
Good fin guides are nice, but not essential, at least for Sport rocketry. Remember, it’s supposed to be FUN! people have for years and still do build rockets drawing lines with a pencil and a wrap around marking guide or a metal angle or door or drawer edge.
That varies a lot from person to person. Some of us have lousy hand-eye coordination and lousy-to-nonexistent depth perception and can screw up nearly any free hand operation, so without a jig of some sort it's not fun.
Remember you must draw your fin lines before using Estes fin jig. Jig works great if you do so.
When there are other features to line the fins up with, yes. For a simple 3/4FNC, I just put the body (with the motor mount installed) and the fins in my jig and go. Some slight nudging is occasionally needed, but that's easy even for me with the jig holding things still. Then walk away until the glue is dry. It has never failed me.
