You can help me to isolate the problem some what with an 
experiment. Run your system with an independent Rx battery 
along with the flight battery. BEC will be left un-used this time.
Let me know your observation. 

Ask your self if you have follow the application note with the
motor package, 100%? yes full 100% with no smart get 
around tricks or assumptions.

Also, experiment without the prop. with motor free run with
throttle cycle up and down from zero to full. Case 1) fast or
half second cycle, pause 5 second at min. rpm, 2) very 
slow or five second cycle, no pause.  Your helper will
operate the Tx and the observer will hold the plane and 
walk away from the Tx. Let me know your observation. This
is like doing the (YK) ground range test.

If you want, experiment with a 2nd 39" terminated at the 
input transformer-ground at the chassis (that is the point 
tracing from the input transformer metal case but at the 
solder side). Run this in opposite direction against the
stock wire antenna. They share a common axis. Let me 
know your observation. 

Range test with reducing servo each round. Also try
one servo rotate from one control-channel to another.
Find out if it is just the throttle channel or common to
all channel is affected by what rpm (hi-mid-low?).

If you have a Brushless motor, it runs on a uP paced
by a digital clock and its harmonic can capture your
Rx response. Experiment and operate the flight power 
plan separate from the other electronic in the plan cycle 
at a close and not too close proximity (plus throttle 
up/down cycle) and observe Rx response. 

Let me know what did you find.
