First build trouble shooting

Hi Forum!

I am brand new to this forum, as well as building quads.

For the past week, I have been constructing a full-sized quad with the following specs:
  • APM 2.6 Controller (bought of eBay)
  • 4 x 1000 kv brushless motors
  • 4 x 30A XT-XINTE ESC
  • 2200 mAh 3S battery
  • 4 x 10X4.5 props or 80x45 props
  • FS-t6 tx and rx
I double checked the proper prop orientation and rotation.

What has been happening, is when I exit the idle/arm mode and begin to accelerate, the copter flips. The first maiden I did, it flipped every time (later realizing that the props were on wrong).

Later, I fixed the props, and it still flips.

Also, when I push the pitch gimbal forward on my transmitter, the copters motors would make it push the opposite way.

Anyway, I realized that one of the motors seems underpowered, as it takes more time to spool up to speed; compared to the others.

Now it flips into the direction into the underpowered boom (presumably because it is off balanced).

I did calibrate the ESCs by powering them up with the throttle stick all the way up, then bring it down and wait for the beeps.

Any help would be appreciated!

I will attach some photos and videos in a little bit.

Go into your TX menu and reverse that channel (probably 2).

That usually means you have not connected the correct motor to the corresponding position on the FCB or the inputs from your RX.

This is your TX.
Ch 1 = Aileron
Ch 2 = Elevator
Ch 3 = Throttle
Ch 4 = Rudder

Double check your documentation and make sure you have them plugged into the correct inputs on the APM. Do the same on the output side with the 4 motors.

Thanks for the replay Jackson!

I know that the inputs are correct, because you can see the values when you calibrate the APM for the radio.

Also, I'm positive I have the motors connected correctly.
