Good news, thanks.

Last year we had one for the June launch and club BBQ, but perhaps that was an exception. I'm still shooting for being there at least Sunday morning, but I may be able to come out with the family in ...

I agree that for an altitude shot, the J570 would be superior. But for a speed contest, or even just a personal speed record, the J825 would be pretty spectacular. My main question is, does it exist...

I was poking around on thrustcurve.org, and I ran across a spec for a 38mm Aerotech J825 that said it passed certification last year. It's on the combined TRA/NAR motor list, but I don't see it on T...

I thought you were going to use an H268. Doesn't it sim a little faster? The impulse is almost twice as high if you can fit it. If my little rocket passes an Estes motor checkout this week, and I ge...

Tim, do you stock the H238 in a 29-180? And has anyone had trouble with it? I'd like to get some data at 100 G's+ with my new 250G-capable Parrot, and I think my new rocket will be able to take it.

Cool. You should try it again, this time with a Parrot and a Beeline, and go for the F, G, and SSS contests.

Thanks. I think I'll be making carbon fiber rockets from now on. Here are some things I learned along the way: Doing the layup with the marble floor tiles, it's very easy to get good quality, so in ...

Some other folks in the club have made a nicer looking rocket, but not me. Hope the fins are on straight 😉

After the first go-around with the sandpaper, the fins are down to 4.1 grams and 0.06 thick. The two outer layers of thin fiberglass are mostly gone. I still have some low spots where the uni tape h...

How was the release film held in place? And where did you get it?

Pictures from Christmas eve: Needs more shop towels to sop op the excess resin. Note to self: The vacuum bag can never be too big Vacuum bagging done Christmas morning. Time for pliers. First look ...

After more than an hour of prep, I'm about ready to mix some epoxy: This time I remembered to close off the ends of the tube so the vacuum bag doesn't push the layup into the tube.

Sounds like a good class, Warren. Mule, Here's a picture with some of the materials: The unidirectional tape is dry, and comes rolled onto the cardboard rectangle. It started as a 4-foot roll, and yo...

Yes. I protect the floor tiles with a layer of thin plastic sheet, then one layer of blue shop towel, then a layer of pink fine-weave peel ply next to the wet layup. So far the shop towel has absorbe...
