Hello Jeti,
i think there is ab Bug since the latest V2.20 firmware.
When programming a Helicopter with 120degree Swashplate (everything with default parameters)
all three TS-Servos show up in the Monitor with symmetrical % values.
e.g. : TS1 = 16% , TS2 = 16 % , TS3 16 % = OK
but
If one of the Servos will be set into reverse mode, values are not symmetrical anymore.
e.g. : TS1 = 16% , TS2 = 16 % , TS3 -15 .% = very bad for precise F3C flying!
I think TS2 is running out of ballance because of a bug in the Software V2.20.
The value in this case should be the same (16% - 16% and -16%)
I have tested the other releases already:
V1.07 default = TS1,TS2.TS3 auf Servomonitor symmetrisch - nach Servoumkehr = TS1,TS2.TS3 auf Servomonitor symmetrisch
V1.07.1 default = TS1,TS2.TS3 auf Servomonitor symmetrisch - nach Servoumkehr = TS1,TS2.TS3 auf Servomonitor symmetrisch
V2.01 default = TS1,TS2.TS3 auf Servomonitor symmetrisch - nach Servoumkehr = TS1,TS2.TS3 auf Servomonitor symmetrisch
V2.20 default = TS1,TS2.TS3 auf Servomonitor symmetrisch - nach Servoumkehr = Servomonitor ca. 0,5% unsymmetrisch
