You can see the altitude after you get it back and download the track from the collar. You cannot see it live. Though you can see how fast it is traveling (horizontally) live.Edward

Do either of the dog collars tell the max altude?, (within 5 seconds, according to garmin)?Seems to be the most fail safe way to find my rocket, incase i blink.Daivd

I got my DC20 (in the orange case) in a 2.5″ coupler in my rocket. I didn’t like taking it apart since it was in such a good weather and waterproof housing.Edward

I think I figured out why my drogue descent rate was 180fps – I was looking over the data, and the charges weren’t nearly as energetic as normal. My apogee separation was somewhat delayed, and only reached a peak of…   Read more»

I assume the $85 was just for the transmitter right? Do you guys use them in the cases? Can you reposition the antenna? I’m trying to figure out how small a rocket diameter it would fit in.I have both.38mm for…   Read more»

Ken, that is a very good point (about battery mounts). I don’t trust them anymore. I use black tape and call it good, even on the most aggressive of boosts…I have allways taped them in. 200 mph I mean…   Read more»

We did recover the Thor, but not until Sunday morning. The reason for the discrepancy between the GPS reading and the actual landing spot became obvious after downloading the tracks. The Thor track ended roughly 1500′ above the ground. Apparently,…   Read more»

I agree about the “drop it as fast as possible” comment – my Amraam had a descent rate of 180fps under drogue (somewhat accidentally though – I’m not sure what happened, but normally it is somewhere around 110fps instead). Total…   Read more»

I read a paper a while back about parachutes and talked to a rigger friend of mine who dropped cargo out of planes. The paper said that in some situations you can get something to fall faster with a parachute….   Read more»

I didn’t have a drogue. None. Just shock cord. When you get into 250 knot winds, you have issues….I can count on one hand the number of times I’ve used a drogue chute or streamer. I typically come down as…   Read more»

You need my drop like a rock drogue (36″ parachute with a 14″ spillhole) 🙂 The descent rate under drogue was 106 fps, only took a little over 3:45 to come down. Still decided to drift 2.9 miles out.Edward

I landed 7.28 miles from the flight line. Never once lost signal. It was about 2 inches from where the GPS said it was 8) I’d never have looked within 4 miles of where I landed had I been using…   Read more»

I wonder how much altitude I lost due to getting tipped over as I slowed down up top?

24′ :)Edward

I had a DC30 in mine.I let it sit after it landed, for an hour (yawn) waitin for Wilke to get his Lead Sled Moving! Mine landed 2.96 miles away. When got there the reciever was telling me it was…   Read more»

I flew my DC-30 to 17k, and I was back at the pads in ~45min (I landed 3/4 mile or so from the pads, and in an area where there really wasn’t any road that was any closer). Walked almost…   Read more»
