So I've used this only twice and both times it didn't really log anything, or at least I can tell the data is incorrect. The first time I thought I needed a vent hole, so I drilled one (this was probably a year ago haha, haven't used it again till today). Now today with different rocket and vent hole, from what I can remember last year, very similar readings. Altitude 2 ft Ejection 2ft Flight duration .4sec Top speed 54k Peak acceleration 40g Coast to apogee 0sec Flight descent 0sec Battery level 93% Thrust time .4sec I'm turning it on and holding and releasing when it says launch and then ready. Am I doing something wrong? It should have been a couple thousand feet at least, not 2ft. It did sit on the pad for 7min while I got GPS tracker ready.
