After a trial run of my sctrach built slowstick which contains A tower Pro combo 25ampMAG esc and 18T brushless TOWERpro motor with 11x4.7 prop 11.1 BATTERY 20c MICROSTAMP castle esc 9G servos,
During the field  motor mount was broken and it droped with wires connected to esc, Then after connecting motor it just starts and tends to vibrates but doesnt spins complete cycle. saw an connector was broken then after resoldering it also same thing happening.

she was in prfct wrkng condition before the field.

Please suggest/Advice.

rahul,
1. Remove the three wires from the ESC going to the BL motor.
2. Take a multi meter and put it in continuity mode X1 range.
3. Check continuity of the three leads coming from the motor. All of them should show practically a short.
4. Mostly one wire will be open. If so find out where the disconnection is and repair.
5. If all wires from motor are fine check the 3 wires from ESC for any damage.

If Motor is vibrating instead of spinning, simply means that only two wires of the motor is getting power from ESC, either ESC is faulty or Motor winding is faulty. Please check

Done took one line tester(rs. 25) from local hardware shop tested all 3 wires wires were ok only one Gold dean connector was loosend, pilld it off , brushed the wires and resoldered the Goldy into it. and she was back to life.

Thanks All.
Mean while mine new stuff arrived
I ordered

Turnigy Micro 1818 3500 KV micro brusless 9g
Turnigy Plush 10A micro Esc
480 Rhino 20A Battery for my
Slofly 28.

on the way
2  3mmx1000mm carbon tube
2  2mmx1000mm carbon rods
2  3mmX1mmX1000mm  cabon strip
from the said vendor in bangolre.

one challenge is that now since micro motors wires seems to be delicate
which is the best way to connect to esc other than Gold dean connector .

battery is having female JST connector where can I get male to pair it with esc?

You can go with whatever connector you are comfortable with, just make sure that you do not go over the rated amps for that connector.

There are other threads here on connectors, like this one :

http://www.rcindia.org/beginners-zone/how-to-wire-esc-to-batter-and-motor/

Hobby city motor esc battery,
carbon rods RCDHAMAKA from site reference of this site.

rcforall has JST male connectors.
I was most comfortable using 3 pin Berg/latch/pin connectros for small motors.
You get gold plated ones from SP road shops. They are light weight and the best part is you can spin the motor reverse by just reversing the connector
