Hello

I recently bought all the components to build the "Lumenier QAV-PRO Nano Whoop 2" Cinequads Edition Bundle" from getfpv.
Spent the last few days trying to get the build off the ground sadly. Soul destroying to have a cool toy that does not work.
Is there any help or advise?

Problem
There are a few problems in my understanding.
1.The motors at idle with a battery connected have a slow pulse.
2. When I touch the throttle the motors automatically escalate very high and the drone flips out.

Troubleshooting
I am confident my motor direction and order is good in BetaFlight and the motors sound fine when testing in Motor Test Mode
The Calibrate Accelerometer button shows the drone is in the correct direction and orientation.
Tried multiple presets and reverted to default a number of times but still have the same problem.
Changed the ESC mounting to include some gummies for cushion and removed them with the same outcome.
Moved the ESC from the bottom mount to the top mount.

After each of the above steps ensured the calibration, drone orientation, motor direction and motor order was good.

Given that it is making no thrust as the motors speed up, that tells me that your motor direction is not correct, and they’re all spinning the wrong direction, or they’re mounted upside down. They don’t appear to be mounted upside down in your pictures, so that leaves motor direction.

With all motors spinning in a direction that pushes the quad down, the throttle behavior is expected- it’s same as if you tried to give it throttle with no props. The flight controller expects a certain movement, but that movement doesn’t happen because there are no props, or in this case the props are spinning backwards, so it tries harder and harder to make that movement happen resulting in speeding up motors with no throttle control.

If you hold a piece of paper above the quad (watch your fingers- maybe tape it to a stick)- is it pushing air up? It should be sucking air down.

Thank you very much for the help
I checked the motor direction again and it looks like my motor direction is the same as the diagram.



This is a video with a piece of paper

Hrmm. If motor direction, prop direction, and prop orientation are correct- it should be at least jumping into the air and flipping out/flipping over when you give it throttle even if your motor order, board orientation, or the checkbox that says, “motor direction is reversed” on the motors tabs is incorrect.

Can you post a clear top down photo that shows all props?

A top view of the props

Here is another video showing what the throttle does just before it the drone freaks out

i beleive only the rc commands might be a possible issue than, check the receiver tab in betaflihgt

very well how you privided all that infos, thats how troubleshooting makes most fun :-)

Thank you for your kind words and help
This is a screenshot of my Receiver tab


There is movement there.
Is there a setting there I could be missing?

does roll pitch and yaw move as they should?
i thought it might be the channel map

Could you please go to esc-configurator.com and then connect your quad via usb, plug in a battery, hit connect, click read settings, and post a screenshot?

If it’s not your channel map like Hugnosed was thinking, I’ve got an inkling of an idea of what it might be.

From your video, it is hard to tell, but it looks like you have the props on upside down. The prop blade should be curved downwards like a sad face or the "hollow" side is facing down.

With a pusher quad, the motors are upside down, so props actually go on upside down when putting them on the shaft (if you setup your quad in the correct orientation in which case you push up the props right-side up).

This is interesting!

Warning: Turn off your radio! Otherwise flashing might fail, especially on highly integrated AIOs.
Note: Make sure you've taken the propellers OFF before doing anything on this tab.
Note: Connect power to the ESCs.

Missing an ESC?
The amount of available ESCs does not match what the flight controller is reporting. This can have multiple reasons:

• The ESC was not ready yet. This can for example happen if it is playing a melody. Also a previous flash could have gone wrong and it needs longer to boot up than usual.
  
• There are simply not more ESCs connected.
  
• The MCU of the ESC is defective.
  
• Try a different USB cable - sometimes they are not properly shielded and might result in such errors.
  
• Make sure your radio is turned off while interacting with the configurator. Switched on radios have been reported to cause issues with electro-magnetic interference and thus failed read/writes.

Crap, my bad. Your aio is running BLHeli_32.

Please download BLHeliSuite32, run it, connect your quad via USB, plug in a battery, hit connect, click read setup, and post a screenshot of it.

With a pusher quad, the motors are upside down, so props actually go on upside down when putting them on the shaft (if you setup your quad in the correct orientation in which case you push up the props right-side up).

I’ve been trying to tell from the pics if the props are upside down, but it’s real hard to tell basing it almost solely on shadows.

OP, here’s how props should be.



That black stripe is the leading edge, the yellow stripe is the trailing edge.

Looking at it from the top of the quad down- the leading edge of the prop (black stripe, highest point) should be leading the spin- it should be higher than the trailing edge. If you picture it spinning, it forces air down. The trailing edge (yellow stripe side on these props) should be lower. 

Leading edge should be the most forward part of the prop as it spins, and also the highest.

Leading edge is the direction it should spin.

My inkling of an idea was that maybe you set your esc direction to “bidirectional” rather than “normal” or “reverse”, which is not the same as bidirectional dshot,

Bidirectional on the esc configurator side of things means a 3d setup, where mid throttle point means zero throttle, below that means reverse direction, and above that means normal direction.

I know, it’s confusing- but it is not the same thing as bidirectional in betaflight, where bidirectional means communication between the motor and esc.
