Description

Excellent day!!!!! OMG, was so fun, Tim and I were twins on altitude.

I tried a different way of taping my lens cover on - taping it on the outside of the rocket. Near mach it breached causing buffetting so not the best test for velocity.

While the software transmitted telemetry perfectly, there was a bug with the audio at max altitude where it just kept repeating max velocity max altitude over and over. I had my IF condition backwards. Easy fix - That's why I always test my software before releasing in the play store.

Speed:

The only speed I trust is from my accelerometer math, 667 MPH, which is right in line with previous launches with the same motor.

If you take the buffeting out on barometers, it appears to be right in-line. This also is in-line with OpenRocket.

Altitude:
Stratologger Computer 1: 10652 feet AGL
Computer 2: 10650 feet AGL
Insane Rockets Barometer: 10666 feet AGL
Altitude based off of Insane Rockets GPS: 10810 feet AGL
Altitude based off of Insane Rockets accelerometer: 11092 feet AGL
 
Amazing, all altitude readings are within 4% of eachother!

Eggtimer said 10667', MARSA Baro said 10763', MARSA accel said 10797', GPS said 11070' for my launch.

Nice higher flight than me Tim!

My Barometer (on phone) says 10666 - GPS says 10751.3 (AGL) - quick check from one of the stratologgers was around the same - but I can't access until we get home.

That was another awesome flight on the EZ-I - great launch & great recovery!

Need to drag Freddy down there some day!

Notice my velocity is bogus on stratologgers too due to breach in bay window.
