Try taking the main blades off for a spool up test. Might save your gears if the ESC is set incorrectly. Don't let the speed build, just test the soft start is working other wise the tail blades will bite and give you new problems to deal with.
Set the ramp for 10 or so seconds depending on what options you have.
What I think could be happening is perhaps a short soft start time which basically expires while you are moving the throttle stick forward. Then you have full power at the stick (no soft start). The other issue might be a notchy throttle curve - or a combination of both. I have seen Spektrum TXs "pulse" when crossing from one defined point to the next on the throttle curve. My Futaba doesn't do it by my 27MHz JR did. That power pulse might cause stresses on the drive train.
The solution? Not sure really. I'd try making the throttle curve as flat as possible in "normal" curve. Delete as many points as you can basically you have a two point curve and not a five point curve. The issues seem to be when the throttle position crosses these defined points. They appear to "spike" if that makes sense. If you can get the soft start going, you can have a dead flat line for a curve at say 80-85%. That way there are no points along the line.
