Default RE: Low C-rate with 1st flights after winter??

All connections are good, I rechecked this morning.

The temperature was 11 deg. C.

The Jeti-99 has the option to:
1. During flight the controller is recording the following values:

Maximum and minimum temperature including the occurence moment time of the extreme value.

Maximum and minimum current including the occurence moment time of the extreme value.

Maximum and minimum voltage including the occurence moment time of the extreme value.

Maximum motor speed including the occurrence moment time of the extreme value.

Motor run time

Flight time

Error symptoms (temperature, voltage, commutation, current), if occurred


There were no strange measurements after flight. However I wonder how well it measures the lowest voltage value. Also, is there any possibility that the voltage is still OK but that the amps are lacking? (low C-rate then?).

It measured the lowest voltage (36VDC) 55 seconds after take off. You would expect this to happen more towards the end of the flight.
