I got my first altimeter in May, the Adept22.
I spent some time teaching myself the basics, using a Tupperware vacuum chamber and old Christmas lights in place of igniters. Everything seemed to work as expected, so I installed it in my Das Blitzkrieg.
According to the documentation, the existing vent holes should have been sufficient, but when the rocket flew, the only event was from the CTI default ejection charge after 14 seconds. The rocket was undamaged, but the Adept22 was still trilling the waiting to launch beep tone.
I assumed the vent holes were not large enough, so I drilled 3 1/8" holes around the av bay, and launched it again.
Once again, the altimeter failed to detect launch, and this time, the nose cone got a big chunk of PVC knocked out of it. I talked to several people at the site, and they all said the venting was enough.
Did I just get a bad unit?
