Am I going to toast my Ice2 80HV with brief peaks of 100-amp load??
We finally got some flyable weather today - albeit with 15-20 mph dead cross winds - and a chance to test some different props with the Pletty Xtra 30-09 V2 and the Ice2 80HV.
This motor is known for high amp draw, which I also saw in the CC data logs for mine when running even the less steeply pitched PT 20x13, which was peaking at 100 amps. I tested a couple more props today and was hoping to get some useful info from the data logger, and I assumed incorrectly that the data logger simply overwrites the old data, which it does not. So a bit of wasted effort there and no new info about amp draw with the other props, a Falcon 20x13 and a PT 20x12.
Although the amp draw has some high peaks, the temperature of the ESC is barely warm, the motor is only warm (maybe 120degF on the hottest area on the back of the case) and the batteries barely warm, so it doesn't seem that anything is being stressed at all. It behaves like a "happy" set-up, you might say.
It would be nice if CC had an option for overwriting data on the logger! And maybe time/date stamp!!
Next time, the laptop goes to the field with me.

With a whopping total of 10 e-flights under my belt now, I can relate to your need to manage the logging buffer contents more easily. The feature that you want to ask them for isa circular buffer with time stamps at the start and end of a session, or at least with a unique session ID to discern what you have left in the buffer. A circular buffer simply wraps around when it becomes full and startsoverwritingthe oldest data, so you always have the most recent data that will fit the buffer memory that is available. A snake eating it's tail, if you will. The other handy thing would be an LED code/beep code to tell you that you're approaching, or are already into a wrap around condition, thus alerting you to grabthe datafrom the controller before you lose thehistory that you may want.
