Help with motors bayangtoys x9

I had problems with motors on this unit, and I think I crossed polarity when connecting the new motors. When I start the drone slowly, 3 of the 4 rotors seem to be going backwards. I compared the wire colors and terminals in the motherboard to sibling unit and they seem connected right, but the rotors going backwards tell me otherwise.

Should i reconnect the motors with polarity switched?

Sorry. Newb, but I learn fast.

No, it flips over onto one corner which is what started me looking at the motors in detail. I thought a had I've bad mitor, so replaced it with a new one and fresh prop. No luck. Used a replacement motor With same color coding on wires.

Wondering if a crossed something on the mb. I'll do another detailed comparison to a flying version. I bought three...two for kids and a third parts copter. One is flying, albeit needing trim tuning. Second unit just flips despite resetting gyros.

I bought a mix of cw and ccw motors.

White black
Red blue

I replaced a white black motor with another white black. It was a few months ago, but I have also moved motors over from the donor unit I mentioned. Kids fiddledv with theirs and broke connections at the motor necessitating replacement. I'd done this fine a few times, then this last replacement hasn't worked.

Does changing polarity on the inputs change the motors direction? Or do I have the wrong motors in the wrong corners? I have same motor types on diagonals. WB RB. Now wondering if I pulled a couple at a time off during a past repair and crossed up the whole device.

Exact same. I bought three matching x9s from gear best for Christmas.

The replacement motors are 032(?) [Forget exact naming] Motors since the forums indicate that the bayangtoys x9 motors have leads that are too short

Problem was there using all original bayangtoys motors from donor drone. Using new motors changed nothing. I ran short of spare motors cause the kids kept breaking wires and I had to wait for replacement to come from China. Then school life and weather got in the way for a couple months.

The red and blue wired motors go to the front left and right rear of the quad (the side the battery wires come off the board is the rear of the quad.)

The blue wire is negative and red positive..White wire is positive and black negative....it will change direction of the motor if you reverse polarity.

The red and blue you see at the top of the pic is on the right rear side and black/white the right side front...Its opposite for the other side..blue and red are the left front and white and black the left rear

If the motors are in fact wired correctly then its possible you have the props in the wrong places

Thank you. I will review my configuration after the kids go to bed tonight. I would rather let them beat on these a little more before I give them the x5cs I also bought, but am storing.

So checked wiring and all seems in order, but the rotors don't coincide with the motor direction. Front white rotors viewed from behind spin cw-left ccw-right.

Rear black rotors spin ccw left. Cw-right

White props appear to be ccw
Black props are cw

Assuming they blow down...

Have no idea what that means.

White props = 1CW and 1CCW. Same with the black there are one of each.

Look for the leading edge/high side of the prop. Use the leading edge to place your prop. Think of it as a direction pointer.

The top prop is a CCW, the bottom CW.

Looking at done from rear/above as you highlighted...

Thank you very much. Didn't realize props were different orientation within the same color.

All good. I just need to adjust trim. Thank you very much for your time and patience. I now have two working drones again. The kids will be very excited this weekend. I may use the spare parts I bought to rebuild #3 and join them. This was a great foundation to fix these going forward

I have them. Kids are going through motors. Tinkering when props get tweaked and breaking delicate wires. My soldering skills have sharpened considerably.

Here is maybe a helpful tip...When you know you are about to crash ,make sure to drop the throttle completely..Any motor/prop resistance with throttle on can burn out a motor or even the flight board fairly easy.
