A far as I know the the throttle position was learned but this can be checked again. Thanks for you response.
With your model having motors so well apart, you try to get them to run as evenly as possible to avoid assimetrical thrust. No motor or ESC would be perfectly identical especially cheap stuff from asia, but most like reason for your power difference is in your batteries if all the leads are identical. I fly number of EDFs ranging from twin to triple motors but having the power units pretty close to the centre line it doesn't create any problem beside the difference in sound, mainly when I fly my "Mig-29" which might be also caused by the long term wear and tear after over 250 flights.
