I finally got to run the motor in my new Cardinal profile based plane
Axi 2826/10, 4 cell 14.8v TT battery, CC Phoenix 45, ESC, Zigras timer
I set the ESC for :
Cell count Auto Lip
Brake Hard cutoff
Throttle mode Heli Governor High
Brake 50% disabled
Brake ramp immediate
Motor start 39%
Throttle response Medium #5
Timing Standard
PWM frequency 13 Khz
Current limit Normal
Governor gain High 80%
Spool up speed 80%
Zigras timer settings:
Startup speed 35 = 70%
Ending speed 40 = 80%
3 Blips on
Motor start time 2 = 20seconds
Flight duration 5 1/2 minutes
battery fully charged , 11 x 5 Zinger wood prop
starts up OK, turns circa 9 K, for about 4 mins , drops gradually to 8 ish by 5 mins
NOW,........at 5 1/2 minutes blips non-stop until I switch off power, approx further 1 minute
Intend to try turning off the 3 blips at end next, but very puzzled, on re-charging the battery
all else seems normal,
could the ESC or the timer be doing this ?
Any suggestions please ?
