Hi all -
Any ideas would be appreciated.
Here's the issue. About 50% of the time, the system will start up (after the initial "burp"), spool up (with some bit of what sounds like hesitation),
then shut off between 1 and 4 seconds later. In some cases the motor never comes up to full speed, in others it will quit just a second or two after reaching full speed.
Thanks in advance!
Motor: Turnigy Aerodrive SK3-2836-150 with 8x5e prop
Battery: A-SPEC 1.8 mAh 3-cell
Set RPM 10,554 (achieving only 9800 actual but not at a voltage or current limit)
Current draw - 16.8 A peak / 181 Watts.
Minimum pack voltage observed - 10.7 V under full load
Suspecting bad cells, I swapped batteries; all are new and perfectly balanced.
I monitored the individual cells and never saw voltages drop below about 3.5.
I thought maybe the ESC to timer connector was loose, but it's snug.
Timer settings:2 min run, 5 sec delay, ESC Mode: Phoenix new high 10,554 RPM
