This weekend we went down to the local park to start the Servo Timer II trial flights. We flew a total of 7 flights with the timer and thankfully all worked well. Two of the flights included the uMAD for triggering the timer at apogee.
The full launch report along with a highlights video is here:
We are now preparing larger rockets to continue the tests. We would like to do an additional 10-15 more flights before starting a production run of the timers. Yesterday I was going to do some tests with one of the timers, and noticed that I had left the power switch ON, and completely drained the battery over the last few days. So this morning I updated the firmware to flash the LED briefly every 5 seconds to remind me to turn the power off.
