Rough start with brushless motor
 

I have a rough start with my reventon pro and 17.5. I have changed sensor wires, checked soldering and charged batteries. What is causing it? I have a YouTube vid

Some of those solder joints look pretty bad, the 2 on the motor that are closest to the camera look like they could be touching?
Try to redo the solder joins again, maybe you have a buddy that could help out with them?

dry & poor solder joints will cause problems on their own.

check ur A-B-C wires make sure the correct wire is on correct tab,, and Remove all soldered wires clean grind down all the excessss solder and REDO.. try a Hotter solder iron somewhere in the 45watt + range..also check esc cap units solder .. Recalibrate ur ESC to radio..

not sure if u have a link..
what color leds are light on esc???..

Red and orange are blinking. I will redo solder. I have it set at 700 on my iron.

Blinking red led means low voltage.
Blinking orange led means over heating esc.

I could not find anything for the combination of the 2 leds blinking.

I agree with the guys posting about the solder joints, cold or dull solder joints can cause these problems.
