I recently crashed my P2 and damaged one of the arms badly.  Both the shell and one of the ESCs needed to be replaced.  To be extra careful, I also replaced the motor (M2) from the damaged the arm.  I made sure to get use the correct version of the ESC and motor with the replacements.  I repaired everything, but when I try to lift off the drone tilts backwards in the direction of M2 and M3.  I checked the soldered connections inside and everything seems fine.  No matter what, I'm unable to get the drone to lift off straight up.

Can this be repaired or should I just sell it for parts?

Thanks

Let's see a photo of the P2 with the top off.  Thanks

[size=14.6667px]Update: performed basic and advanced IMU calibration on verified level surface. Performed compass calibration. Bird is still immediately tilting backward upon take off with full throttle. To get a better sense of the exact direction it tilts, I anchored it and could then see that it's tilting downward towards M3 which is the ESC/motor that I replaced. I assume this means that it's not getting the same amount power/lift as the other motors. Attaching pictures. Did I solder poorly? Any ideas?

It looks like your red and yellow wires are backwards.

Good eye, Scott.

Hope it’s helps

Somewhere out there in this world, the OP means to thank Scott for his help...

Thank you!!

Well spotted

red and yellow wires are a cold solder joint, this can cause problems.

edit:
after looking at the rest they all look cold soldered

Replaced my P2 shell often. You cant kill it ;-).

I would double check those solder joints as others have mentioned.  Heat that soldering gun up and tin the tip. Some of those look a tad scary.
You get airborne, its a great drone and easy to work on. Obviosuly they are out of warranty now,.
