Strange Behavior of ESC and/or FBL????
Posted: Sat 24. Mar 2018 18:52:02
Hello Tomas,
this afternoon I made a testflight with my Trex550X.
FBL Spirit pro
ESC Align 100 BLE
Telemetry Graupner HOTT
Transmitter Graupner MZ 24
Receiver Graupner GR16
SUMD
Governore Mode ESC Internal/ not store
RPM Cable of ESC not connected with Spirit
RPM Parameters (gear translation) input in spirit unit
I wanted to test Governormode of the Align ESC with two Banks (Bank0 60% flat Throttle,
Bank1 70 % flat throttle).
Still on the ground in Bank1 with 70% after perhaps 1 minute test on the ground the RPM was falling down, I switched into Bank1 with 60% and the RPM raised. After switching again in Bank1 the RPM again got low.
I felt almost like a soft cutoff, when Lipo suffers with low voltage. (It was a 6sLipo with 4000mAh, the temperature was about 5 degrees)
Now followed a strange behavior of the ESC form me.
I then cut of the engine , and the ESC cutted off with engine control too (always 3 short beeps from the motor).
I tried to connect the spirit with the spirit software, to get a log, but no connection.
Connection was only possible after reconnect the Lipo to the ESC.
Fort he next groundtest I used a 5000mAh Lipo and removed the telemetry connection.
All worked well and a following flight with another 5000mAh Lipo was fine too.
I´m now afraid, the strange behavior oft he ESC could repeat in flight, because I´m absolutly perplexed, what could caused this strange behavior (ESC, Governore Mode, Telemetry, FBL????)
Could you please give me an advice?
Thanks in advance with best regards
Roland
