Try a big battery to see if it is a LVC issue.
I'm using an 850mAh batt intended for the plane...I do know that twins can get into harmonic issues...I have the same motors/fans running in single engine planes with no issues like I'm having in the twin engine F-15...I could check the motors individually but that would mean removing shrink tubing and de-solding components...YUCK!!!......
