Breeze flips over on take off

[Shawnp26]

I got a error about the motors failing on the app I was about 10 ft high coming Down to land it. It fell, broke apart. After almost crying, I put everything back together. Noticed blades were toast. Correctly changed them in the corresponding spots
(diagonal A to A, B to B). I did however, crack the sensor glass on the bottom of the drone. And now one sensor (looks like a drone) on the top of the app seems to linger yellow at take off. Here is what is odd to me. Fully charged battery, re calibrated the drone, updated firmware (it was already updated), correctly changed the blades, reset the drone via button in the USB slot. Now the drone acts normal on boot up. Although, while trying to take, it now flips right over in the same direction every time. I have called yuneek and was booted from the queue right at 5:00.

Have you done a calibration?.

 

[Shawnp26]

Sure have. 3 times

>> Noticed blades were toast.
For the propellers, they gave only 4 spares, Breeze needed 8. Did you buy 3rd party propellers to replace all 8? Yuneec OEM props weigh lighter than 3rd party props.
>>Correctly changed them in the corresponding spots (diagonal A to A, B to B).
A, A are shown in picture. Note how the propellers are installed. Incorrect placement can cause flip.

All the blades that were replaced were OEM. They were also the first thing I triple checked. Lol. I think I’m going to bare a 1-2 hour hold time and call just to have me send it in. I went a couple days thinking for sure i screwed the orientation up, but I’m 100% sure they are on correctly and that they are OEM. Any help is appreciated, thank you

 

[nikono]

Compare the orientation of your propellers and mine as shown in picture. Technically, the propellers blow down for the drone to go up. The flip could be caused by one side blowing down and one side doing the opposite.

 

[Shawnp26]

Just checked. Looks good...

The "A" motors spin anticlockwise whereas the "B" motors rotate clockwise when seen from above. So check if the leading edge of each blade is closer to you when you look at it from above. Try really hard to visualize if both blades of each motor blow downwards when you spin it slowly in the correct direction.

Let me assume you did all of the aforementioned carefully and many times.

Were the cables to the motors dislodged?
Are you sure that the electronics did not suffer damage?
Did you know that even one single flip could damage one or more blades beyond repair, even if the damage is hardly noticeable - you only will have it flipping again. The prop guards might help.

So if you can rule out every point of above the only course of action would be to send it to yuneec.

 

[Shawnp26]

There isn’t anything wrong with re checking and checking again. I re-checked and they are correct. I was hoping it would be something stupid I over looked. I will call yuneek today and see how it goes

 

[airborne]

Sorry, feeling with you

Mine flipped instantly because one of the motors didn't spin at all. Many will think that one should notice a thing like that but I can assure you that the flipping lasted only a fraction of a second resulting in a general motor stall.

Good point!! I tried to test this by holding the drone and hitting take off. It “felt equal” as in not trying to flip or anything. It tried to go up even faster as I he’s onto it. I’m lost with this one.

Is your sensor glas still broken? And did you remove the remnants of it? Maybe the motion sensor has difficulty to judge movement through broken glass?

 

[Shawnp26]

Yes the glass is still completely broken. I did some testing just now and the sensor with the drone is ONLY blue when it’s about 1 ft off the ground. If I slowly bring it down to the floor it goes yellow. I bring it back up and it goes to blue. Contacted yuneec and will be sending it out. Hoping that it will be covered under the warranty.

Could it be that the sensor detects irratic movement of the drone because of cracks in the glass? Tries to compensate this none existing movent while it shouldn't?

If this is the case than removing the glass completely might be a temporary solution.

 

[Shawnp26]

The glass was completely removed. I haven’t shipped to yuneek yet. I re calibrated it and it actually spun in circles until it crashed this time rather then flip right over. Wondering if this is relevant to anything.

To be sure this has anything to do with the sensor you could disable GPS. (Or have you already?) GPS on in covered spaces can give epical results ;-)

 

[Shawnp26]

I uploaded a video if anyone wants to see what this thing is doing.

The yellow sensor will only go blue if I bring the drone off the ground about 1ft.

The IRS being yellow until a foot or more above the ground is normal. The other part is not! It looks like a squirrel that has been pigging out on mushrooms. Time to send that thing to a repair center if it’s still under warranty.
