Oddly enough, there's a default windows font called... wait for it... "Stencil!" It's a little too bold, but it looks pretty good.

To put some scientific/mathematical background on all of this, I present the following.

The entire point of a fin is to allow the rocket to fly at 0 angle of attack (AOA). The angle of attack is...

They actually already have at least one (that I remember) model rocket. There is a scale Soyuz done for the World Space Modelling Championships that is absolutely gorgeous. (And still missing a...

That doesn't sound too bad as far as weight goes, though 20-25 pounds would probably be closer to ideal. Just be careful, if you land too hard, it might crack in half like the real one! :p

Shiny! What kind of all-up weight (before and after burnout) are you looking at? What sort of wing area does this beast have?

And, of course, the most important question of all, will there be...

If you're going for lightweight but need stronger than standard Estes, order the -H tubing from Bill at BMS. For anything smaller than a 5 or 6" tube, the LOC tubing is way stronger than it needs to...

It looks like part of the motor fits in the retainer, so I don't think it's sticking out too far. I'd have to agree, I don't think this is a good candidate for RMS. Too much chance of losing the...

Maybe I missed it somewhere else, but what is your shop set-up? I do some basic machine work at my university's shop. We have four Bridgeports (one with a CNC retrofit), two South Bend lathes, one...

I like the sanding sealer/primer/filler method myself. As mentioned earlier, papering leaves at least one edge unfinished. Sealing with a good wood sealer or nitrate dope gives a good consistent...

Assuming that the rocket is traveling at terminal velocity when deployment occurs, deployment force should be roughly equivalent to the weight of the rocket.

Fibafilm/Micafilm is indeed covering material. You do not need to bake in the folds, however. A good crease with the back of a butter knife or your finger nail should do the trick. I placed 4th in...

I've always had the tracing paper tear when used for competition rockets. It is the lightest easily creased material out there, though, so if you can get it to work, more power to you.

I use...

Oh, and a quick suggestion with the burn string/rubber band. I used to just wrap the string like that until it got caught in the grain of a tail. You can imagine the results. Now I use small hooks...

I didn't see this thread back in '11 when you flew, so I'm glad you brought it back! A truly impressive build, especially for having little glider experience. Most people start with sliders, and I...

First, a B6-6 will find the rocket in the ground before the parachute is deployed. A B6-2 would be a much better bet for the first flight, then, if you find the delay is too short, you can use a...

I considered swapping for 24mm mount, but I wanted to do a good finish, and therefore get it back. I figured a C6-3 would be plenty of flight for this bird.

And... done! I did a couple of passes with 600 grit sandpaper, then shot a final coat of color. Apply decals, apply Future, and voila! Finished rocket. The finish isn't perfect, but it's far...

Sounds good, let us know how it goes.

And the kid that got severely hurt a few years ago was only flying an A motor. The last thing this hobby needs is a viral video with someone getting hurt with a rocket. There are enough people who...

Do you want it to fly like a rocket or like an airplane. Or both?

If you want it to fly like a rocket, just put a long (~9") pod on it and recover with a streamer. That would work just fine.
...

If you're into old timer aircraft at all, nitrate or butyrate dope works well as a sanding sealer too. I use it because I build rocket boosted free flight gliders and the larger ones need esaki...

I think my brother invented this technique. (Or if not, highly refined it.) For E-eggloft at NARAM 52, he CHAD staged a D12 to a D12 in just this manner and did it several times before if he is to...

As I recall, the older twist lock retainers have a good bit of material that you could knock off so that the case will fit. A couple pictures would help.

That is really cool. I wonder what else you could make like this...

Just a quick update. I'm a little impatient, so I carefully put the nose cone on for some assembled shots. Going to let it dry until Friday and do some sanding, then apply the decals and clear....

I've got three coats of color on both the airframe and the nose cone. I sprayed the cone flawlessly, but managed to get a run in the airframe. They both look like they need to be wet sanded, so...

Found a can of the old Krylon grey primer, so shot two coats of that and did some sanding. Turns out I've had the skills for a good finish all along, but not the patience. The finish isn't perfect,...

I think it's an "Elliptic II" because it's two-staged.

I seem to have found the secret to my woes: wet sanding! I've applied a coat of Testors rattle primer (not my choice, but what I had on hand) and did a thorough wet sanding with 150 grit paper. I...

Your rocket looks fine as far as stability is concerned. As far as the sim goes, don't "trust the sim." Instead, take the CP number that OR gives you and mark that on your rocket. Then use a thin...
