Flying P2V+.  I had a serious crash last weekend.  I broke the shell and on of the ESC was snaped.  I replaced the shell and the ESC.  When I try to power up no lights comer on and the left rear motor makes a tioc tic sound then the pattery turns off.  I never get the LED's to come on.  I looked ever where for an error code or a guide to this and so far no luck.  


Any thoughts???

Check the main board inside of the quad.    Remove the battery.    Looking into the battery compartment,look for stress cracks in the Main Board under TheFlight Controller.     Don't shoot the messenger.   After one of my crashes I had the same problem.     Hope that it is not the problem.     Just offering up advice based on experience.       Good luck man.

That's what mine was doing when the ESC went out.  Tried to power on, then tic tic. Finally got it powered on then CSC to start motors, all but one motor ran then a poof of smoke from one of the arms. You may want to look at the FETs on the ESCs to see if you may have another bad ESC as well as what Michael is talking about.

acenothing Look on your ESC very close to the three soldered wires coming from the motor to the ESC.
There will be a bank of very small computer chips lined up in a row.   Those are the mosfets. They monitor the current flowing into the motors.     They can burn up due to a number of causes.    You are looking for excessive heat damage.   Misshapen or discolored Mosfets.
Healthy ones are perfect square black and shiny.

After reading all of this I cracked open my shell and gave her a solid once over.   Very pleased...found no issues.

Would like to hot glue the the soldered  connections at the ESC.  Which glue could be recommended for the job?
Thanx

Not sure glue would help. I'm back in the air!  
Maybe by securing the wires close to the solder joint to keep the vibration down. Nothing will keep the ESC from going out though.

Good to hear the birds aloft.   I did check the solderpoints for vibration issues....all good.

I don't know why they didn't just put a 3 pin header on the ESC, connectors on the motor as well as the main board. I guess that kept them from making CW and CCW ESC's.

Going to East Texas this weekend for a small family gathering located in the Big Thicket Preserve. Hoping to get some good video.....also hoping my solder joints are good..
