[SOLVED] Drone cant get enough power to take off

[droneanon]

Hi,

I have the drone setup on Windows 7 with PS3 controller. Everything works fine except the drone cant get enough power to take off (it is getting just close to hovering but cant do it).

The Client is telling me I have 100% power (I raised up the power level in advanced mode to 100%).
My thrust is at 95%+ in the actual readout.
The pitch, roll, yaw are pretty stable and I have tried trimming it a bit.
It is not trying to flip over.
My motor PWM are hitting near max on the green bars on all motors.
I triple checked my wiring config and checked the motors are spinning in the correct direction.
Battery is at 3900mV on the readout (nearly full green bar).
Link quality is good.
Standard settings on the rest of the client with client X mode off.

Can anyone help?

Thanks!

In original setup the Crazyflie should take of at about 50-60% thrust when fully charged. I'm guessing you put the propellers upside down?

[droneanon]

I doubled checked that. They are the right way up.

Are you able to post a picture I can look at?

Can you run it while holding it in your hand at full power and then check if any component is getting hot. I'm thinking there is a bad connection somewhere. Most likely the battery connector.

Do the motors spin easily? Do they spin approximately the same duration during the startup motor test?

Another question might be if you chose props from both of the packages or one package. The difference between the two sets of props is subtle, and you need two of each type, in alternating arrangement as described. Perhaps the bags could be labeled.

First time I ran mine with props, I was careless thinking they were all the same and added them all from one package. The result was the same, no lift!

Choosing M2 and M4 from the unused bag, I was in the lift business!

Just a thought!

All of my props on the drone build are marked "A". Let me try different props and see if this works.

I saw no instructions on props type though. Maybe I missed it.

Yep, this is what it was. Two of the blades need to be from the other pack. I'll try this tonight. Looks like you guys probably solved my flight issue. Thanks so much!

[droneanon]

Solved. I needed M2 and M4 to be on the reverse direction of blade.

I had exactly the same issue as rmirwin2. Maybe this should be explicitly addressed in the documentation?

Er... it is:
