You know, after thinking about it some more, raising the throttle above center increases pitch, which moves the servos. These are not 3kg servos, so they are going to strain to raise pitch which could heat the ESC. Steve, you know electronics. What do you think?
Try removing the blades and raising throttle to max. Weak servos shouldn't have a problem raising cyclic with no blades.
