*was* a rocket

[zeketrimmer]

We leave for competition on Thursday

rocket came off the pad at a 45°angle and hit the ground before the ejection went off, everything including altimeter was obliterated

Despite this, it still beeped the altitude of 417ft

Its supposed to go 900ft

Had a Formula 98. Augered in on a K160 and lost tracker signal. Happened to hit next on access road and was found. I got a signal from the LL Electronics RDF tracker once the rocket was pulled from the ground. Thrustcurve shows 5 g's or better for at least 3 seconds and the data download shows the Raven (v2) never detected liftoff. After I soldered power wires on where the terminal block had sheared off.
Had to replace the payload and nose cone. Called it "Was a Formula 98". (Rusty must check it out.)

This hit so hard I almost couldn't get it out of the ground. Was a complete right off. It was a 3" rocket.

Mine was also pretty stubby, spec was 4:1 length to airframe diameter, we had a 3" body diameter and 1' total length.

Yours had a natural crumple zone, mine just shattered like glass

This had a 38mm LOC Kraft tube, on a J570. The Altimeter battery 23A lost capacity in the heat waiting on the pad and could not fire the deployment charge. I had to use the 23A that is all I had after my 357 silver oxide stacked battery pack had shorted out in the storage box.

It was the last day, EX day I waited to fly it on that day, and I could not find anyone that had 357s I could buy or borrow. I waited for EX day as many said it would fold up on the J570 using a 38mm Kraft body tube.

Sue McMurray had tracked it via binoculars the whole time and pointed at it, we saw a Wile-E-Coyote dirt cloud on the impact with the dry lake bed and drove towards that to find it.

PS: I'm not anywhere that FAT anymore

Do you have a backup rocket for leaving Thursday ?

 

[OverTheTop]

Shovel recovery is never good, but at least it is not completely lost, with the ongoing thoughts of it being returned one day that never happens. Some finality is good.

Its almost entirely 3d printed, most of the work is automatically done for me, ill just print another

My rocket was 5' long and 3" in diameter. The crushed nose cone was the biggest piece left. Trash bag recovery.

My entire recovery system including the motor mount was logged in my nosecone along with my crushed altimeter mount and *not so safe and sound* altimeter, it left a 3" crater in the ground full of plastic shards from our nosecone and entire airframe
