I might chug along with an I216 shot of my own... though mine isn't as glamorous (exposed rivet, conical cone, phenolic, thicker fins, etc.). Maybe we do Dr. J the honor of breaking the TRA record twi...

I'm planning to come on Saturday, with my tower. Depending on the weather and how much I can get done, I may fly a carbon 38mm bird with the new CTI I216 motor, and a Raven altimeter in a new Featherw...

Yep. Can't beat that. "Ah-ah child way you shake that thing,Gon' make you burn, gon' make you sting. " Sounds like a CG needs to be centered a bit better, though. 😉

The all-fire current for the Q2G2s is about 0.2 Amps. They can be ordered directly from the Quest website. Q2G2s work pretty well for igniting composite motors too, if you dip them in pyrogen like M...

Hey Scott, So your using the j-tek? What battery do you like to use? Just getting my feet wet, with dual deploy. J-tek?? Whats that? What ever joe is selling. 😉 I bought forty the last time.So th...

If you're using altimeter apogee deployment, you don't have to drill anything out; just leave the delay/smoke in place and just skip the step where you add the BP. If you want to eliminate the possi...

Very cool. Here's my favorite launch photo:

G10 is actually quite a good themal insulator. Good enough that real spacecraft use g10 to make standoffs to attach propulsion fuel lines to cold structures. In the fiber direction, carbon is more the...

I can vouch for a tile saw. The diamond blade works wet or dry on FG, CF, circuit boards, even plywood in a pinch. Mine is a cheap 4" or 5" tile saw I got for cutting tiles (of all things!) from home ...

Adrian, that is co cool! Thanks. The build thread is below if you're interested in pictures and more info: Good news, Joe!

This weekend I'm trying to finish up my Half-Fast rocket. It's a testbed for airstarts and unusual recovery systems. It's a BT80-based rocket with a central 24mm and 4 18mm motors. It also has a no...

Adrian,Thanks for pulling this together.1) is there a particular reason the F motor can't use a motor adapter? It wouldn't be efficient, but would there be any unfair advantage? Generally, the optimal...

When using a vacuum bag, you'll want to put the bag fitting on the bag some distance from the layup since you don't want an imprint of your fitting on your layup. The fitting should be linked to the ...

I'll take a crack at writing down the rules, and people can modify: Goal: The goal of the contest is to safely and successfully fly one rocket with D, E, and F motors in 2010, to the highest combined...

A Raven, a beeline, and a battery can also fit side-by-side in a 24mm airframe tube, but you have to spread them out a bit more so that the total length is more like 2.7 inches. There's also no room ...
