You're not the first person I've heard say that about the Raven - but on the other hand there are many who swear by it. I have/had flown dual-ravens a number of times in other rockets both before and since, and the trace data from both of them have always indicated flawless performance. Never...

In my case, the battery was fresh. I always flew on a fully charged liPo with my Raven. There were two things I did differently on the last two flights (the successful one on Saturday and the lawn dart on Sunday) than any previous flights: 1) I flew with only 1 Raven altimeter 2) I flew with a...

Sometimes, even when you've ground tested - and even flown successfully the day before - this can still happen to you. I flew my 3" Hawk Mountain Talon (which originally cost me $600 back when fiberglass was somewhat more rare - and expensive) on a Saturday to about 9000 ft and recovered it...

This article describes (as SpaceManMat speculated earlier in this thread) that the unlock of the feather at no less than Mach 1.4 is to prevent transonic buffeting from causing deployment.

Awesome! I'm in! Thanks, Tim!

Orbital update. Also this.

I bought it and activated it before I ever tried using it. What makes you say it isn't activated?

No wonder I'm so confused. What "Output settings"? My main screen has only "Input settings".

No, I imported 1080p 30fps .mov format. The output doesn't appear to give any options when you "create video". It creates an .mp4 file. How does one change the output format?

I just used it for the first time. I have 2 complaints about Dashware after this first attempt: 1) Video output quality is inferior to original (input). 2) Sound in the output file is 0.7 seconds ahead of the image! I hate poor video quality, and even moreso I despise audio sync issues. I...

That's pretty cool. What form was your data in - how did you export it from the featherweight software? I have a video and the accompanying ".fipa" file from a Raven, but don't know what to select as the profile when importing the data.

My wife took this ground-view video of my flight with her iPhone. https://www.youtube.com/watch?v=oiYCXFBwc54

It's a MonoPrice MHD Action Camera. Very reasonable, and in my opinion the very best bang for the buck - better video quality than the Mobius HD camera. No fisheye like the Contour Roam, and lower profile mounting tab too. One slide-switch to power on and start video. It's even waterproof to 30...

First flight of my 4" Broken Arrow XP today. Details in video commentary. https://www.youtube.com/watch?v=6D_cUZmGnxg

Here is video from my maiden flight of my Rocketry Warehouse Broken Arrow XP. Details in video commentary. https://www.youtube.com/watch?v=6D_cUZmGnxg

Very cool charges! What materials did you use? Do they fit the canister ID? It should be possible for pro-line to make a cap that would thread onto the bottom of the canister, with a hole in it a bit bigger than the wires of the charge. Also a flat, thick rubber washer that slides onto the...

It was the 70cm (430MHz) 100mW. I was stupid and assumed that since the tracker didn't seem to affect the altimeter on the ground, that it wouldn't affect it during flight. It even survived one flight without issue. But then everything went horribly wrong. There's no more sick feeling than...

While the firing FET is not being gated, one lead of the e-match is connected to the battery supply and the other (the FET lead) is open. So you are still injecting any radiation received by the twisted pair directly into the power supply of the altimeter - unless you are using a separate firing...

The ejection charge leads can act as antennae, directing the radiation from within the bay into the altimeter. One could perhaps employ ferrite beads on the wires to choke the RF, but this would require some design expertise that is outside my comfort zone.

I flew my 3" Hawk Mountain Talon "Back in Black" many times with no tracker. One weekend I installed a BRB GPS into the AVbay on the opposite side of the sled from the Raven altimeter. It flew once in this configuration to 9300 ft on a LOKI L-1300 (video here). The next day it flew again in the...
