Brushless motor making sounds and not running

I have a new FMS 1400mm A6M3 Zero army green v 2.0 (witout extra servos for closing landing gear doors).

I'm not getting the engine to run at all!

It sounds off a beeping sound (3 short, then 3 double-toned sounds) and the engine "nudges" back and forth at every sound.
I can tell it's getting power as it won't easily spin round as it does when the battery is not connected.
I've charged and rebalanced the batteries (2700mAh, 4S, 14,8V Zippy which I ordered from HobbyKing )

What is the problem?

Can someone help me out?

It sounds like it's in programming mode. You may need to reverse your throttle channel on the tx.

Before powering the plane, are you certain your tx throttle is all the way back against the stop, and your tx throttle trim is all the way down?

I tried to set the thrittle and trim all the way back,but I havent tried to reverse the channel.

I just noticed that if I don't touch the throttle at all while it's beeping, it starts up a beeping sequence; 4x2 beeps, then 4x3 beeps and so on.
The manual staded a 2600mAh battery was required,but I have a 2700mAh; do you think this has anything to say?

pretty sure you need to reverse your throttle channel. Sounds like the esc is seeing full throttle, which almost always means it is waiting for programming of some sort; so, reversing the channel should do it. Or, push the stick all the way UP and power the plane, and see if things initialize and moving the stick DOWN starts the motor.

Do you have a Futaba tx??

That did the trick!

You were right; I only had to reverse the throttle on the transmitter:-)

Thanks for your help!
