Tamiya BigWig Steering issue

[petenz]

Hi, I have a Tamiya BigWig (2017 re-release) I am building.
I seem to be having a few issues with the steering / servo.
Radio gear is the Tamiya FineSpec 2.4Ghz system with TSU-03 Servo / servo horn

Turn on transmitter first and then when I turn on the RC car (switch on receiver) the servo turns to the left - hence steering is not straight.
Turning transmitter on and off from that point the servo then seems to rotate back opposite direction a few turns.
The steering trim setting on transmitter is in neutral.

End result is the steering is just not straight.

I 'think' I've set the servo up correctly in that servo was installed in neutral position
Transmitter and receiver paired as per Tamiya FineSpec manual.
Motor runs fine in forward / reverse, just the steering I'm having issue with.

Any help appreciated. Thanks.

Was everything powered on while you were installing the servo saver? That's the only way to find true neutral on the servo.
