Each of those things would take very little time to fix. Maybe someone who is interested in the rocket will do that.

Wonky how? The one from Apogee looks right to me.
If you have the rocket in front of you, why can't you use that to build the file?

It's been what, 2 years since K&S offered the upscale Scorpius kits? I recently got around to painting and flying mine. Great kit, super components, makes a really impressive model.

Here I'm...

Sean flew this glider really well today. Very high boosts and he picked good air.

You used TTW and still got vomit vision on your flight? They weren't really all that square then. Could have been uneven rounding causing the spin. Got photos of the fins of the spinny rocket?

If Cosmo has an issue with me sharing them, I'll take them down.

You can use any additional onboard electronics you want, along with one of the approved altimeters for altitude readout. You cannot use any additional pyro other than what is provided as an ejection...

And then you can make it a two staged Bumper-Wedgie.

Puff rockets. http://www.narhams.org/library/PuffRocket.pdf One of the go to tools for when we can't make a demo flight but need an activity for a museum or other group of kids. Easy to make, and...

That would be a good name for a band.

The Jet Freak separated cleanly on each drop. We were both too busy to take pictures after the drop. :)

kj

Here's how I have done it:

Make sure your nomex is large enough to completely cover the top of your body tube, with some overlap. Place the nomex across the top of your body tube and push down in...

Took Scott's Jet Freak up under my Radian for some test glides to check the trims. Great weather for it, and we got in about 3-4 flights to check things out without risking a rocket boost on an...

I worked a little on it during the last club meeting. Have to start getting busy on a scale model, so this will be my project to work on when I feel like throwing that in the trash.

Combine that with a data sheet of BT sizes and you can get a nice user interface that fills in the ID and OD fields based on selecting the BT name from a drop down.

Is a very pretty model. Nice and impressive in person. Mine is still in parts. :(

Are you planning on a rear motor that ejects? What does your tail look like? You could have a movable elevator that is locked down for boost by the motor pod and then pops up (like the Sky Dart,...

Sweeping the wings will give a dihedral -like roll stability benefit in a flat wing, but you need more than a slight sweep. Take a look at something like the Twinsee here...

That's temporary til they get their new shop set up.

Finalists are listed. The cut off score was 16.12- hope that was you. :)

I saw several teams get very close on the altitudes but get hammered by the 4x time penalty.

For small tubes I use a dental pick that I straightened out. I have a 1/16" hole punch too, but it doesn't have a long reach.

You see that a lot with motors that have a stick on label. The casing is sized for the tubing, with a little wiggle room, and the label is too thick. Normally I don't have to peel the whole label,...

Also when you are using the Estes wadding, don't ball it up into a big wad and stuff it in. Lay the sheets across the open end of your tube and poke them down in with a pencil or something. That...

Rocksim with the default settings usually will be a little optimistic in the altitude it reports. There are a couple reasons for this- first is that it doesn't know how much glue you used, or if the...

Glad to see you getting out and launching. About half of the teams don't get that far.
I think you're on the right track with putting the rocket on a diet. Getting rid of the ballast is a good...
