Other-Freddys data from phone-ks

Freddy, your phone had data, but I don't know how usable it is as after ignition, it skipped the first 1.3 seconds. I'll send you a zip of all data and video from phone.
It takes just over a second typically for the video to engage if not remote controlled to turn on prior to launch. By the time the video started, the rocket had already had separation, so according to this, separation occurred prior to that engagement, so less than 1.3 seconds into launch.
Maybe the separation occurred early on and the lower half of the rocket just kept going still with the full power of the motor and stability, it's hard to see the top half of a rocket coming down when thinking the whole thing is still going up. That happened to me once in LaBelle - in my case no one saw the top shear off.
I will setup a download link for you later with all data and video from phone.
Phone battery temperature was well within safe limits the entire flight 42C (107.6F), phone shuts down at 60C (140F).
Unfortunately, data capture skipped the first 1.3 seconds, so it started capture also after separation. I'm not exactly sure what the cause for this is other than the amount of forces at play; your phone battery was punctured. It could have also been backlog tripping the system up because it was told to upload telemetry without cell service.

Okay, I figured out why data did not capture for the first 1.3 seconds.
The phone was in the rocket upside down. My software was set to see that the phone was in portrait mode. Due to that, it thought the phone was oriented up when in the rocket ready to launch, not upside down. Therefore, the application was sleeping as it thought the phone/rocket was not launch ready. Even in sleep mode, once a second I check the altitude and if I see over a 100 feet altitude change, I force it into a launch state.
To configure the phone to be upside down, you must run the insane rockets app and turn the phone upside down. From a second phone, login to the web page and click data, and your launch data number. It will not work if you are not logged in.
You will see a new button, Calibrate. Make sure your launch phone is in the orientation as if it is ready to launch (so in this case upside down).
Tap that button. You will hear your launch phone say calibrate several times over the course of a minute. After it is done saying calibrate, your new orientation is set.
You can easily test your new configuration by quitting the app and relaunching. After the gauges settle in the app and it speaks, turn the phone upside down. You should hear something about "rocket being vertical and telemetry will gather at launch."
For your situation, in the near future, I will probably modify the Insane Rockets app to just have a upside down portrait button to make it easy.
I have updated Insane Rockets app to include Portrait Reverse orientation. Make sure when launching with phone upside down to select that button in settings. Conversely, on your standard portrait orientation for other rockets, make sure to choose Portrait.
From the help:
Orientation - It is absolutely critical that you set the orientation properly for the phone to detect launch. Once set, wait for your gauges to settle and then place the phone into the launch position. In 10-30 seconds you should hear "Rocket is now vertical, telemetry will gather at launch." If you don't hear this, recheck! If you have an advanced configuration, contact me and I'll walk you through the steps to calibrate.
