Fried motor problem

To anyone who can help,

I was inspired by David’s Tricopter builds, but finally decided to go with Jason Peterson’s
My list of parts is exactly as his, i.e. RCTimer’s 2830/8 1300KV Outrunner Brushless Motors and
Hobbyking SS Series 18-20A ESCs, etc., except for the battery.
The ZIPPY Flightmax 3000mAh 3S1P 20C was not in stock, so I bought this one instead: Turnigy 3300mAh 3S 20C Lipo Pack.

I also went for the: Hobbyking X900 Tricopter Glass Fiber Multi-Rotor Frame, instead of his wooden frame.

As I am a newbie to all this I took things very slowly. I flashed the controller with the V1.6 firmware.
The receiver was already bound to the T9X. I chose the Helicopter 90 degree setting.
I checked that all the motors were rotating in the correct direction and the that the yaw mechanism was working via the T9X.
I then tried to get all the motors to start at the same time by trimming the controls on the T9X and managed to get them right but not always.

Finally I balanced the props and mounted them on the motors.
I tried to repeat the process by just giving the T9X just enough throttle to start the motors,
so I was not revving them enough to lift the tricopter, when I noticed the left front prop alternatively turning in both directions then the motor started to smoke!
I switched off and disconnected the battery immediately.
I let the motor and ESC cool down and tried to power up again, but instead of the usual chirping and silence, I got several chirpings from the ESCs.
When I disconnect the motor and powered up again I got the normal chirping from the ESCs, so I guess the motor is fried, the windings do look a bit darker in parts.

What do you think? Was I just unlucky with a duff motor, or did I do something wrong?
Perhaps the LIPO is too powerful for this configuration? (It is only a 3300 20C as opposed to Jason’s 3000 20C)
Perhaps the frame is too heavy although I did not try to get it off the ground.
Or can you think of something else?

I have ordered a new motor from RCTimer and a new ESC from HobbyKing, but I will wait to hear from this site before trying to connect it all up again,
in-case you have some good advice?
