I really can't explain why these propellers are vibrating so much! The motors are perfect. And they are new unused propellers (i know that it doesn't mean they're balanced but the vibration is too strong for it, and every new propeller that I use ends up with the same vibration!) m At the end you ca...

lucaszanella

Yeah the motors are ok! Don't know why this is happening. The props are new, never used! Your GUI data are so perfect, wish mine was like this You can see the photos of the building of my Xcopter and get some ideas since my frame was originally like yours: m m I didn't do anything special to isolat...

i noticed that your sensors are all turned on when you were doing your ground tests. leave all sensors turned off until your in the air and stable. the only sensor you need to get stable is the gyro, its on by default, you cant turn it off. the other sensors will give you issues for now. for instan...

Here's a video of its vibration! http://www.youtube.com/watch?v=yj6XwoVMXcY

lucaszanella

Really strong I changed to new unnused props and they are still vibrating. I can really see the vibration on the GUI, but the props are new and I'm not using prop saver. The motors are attached good and the board is well parafused on the frame. What can I do to reduce vibration? Any filter recommend...

So is this ESC good? http://www.hobbyking.com/hobbyking/stor ... oller.html

Will it work?

Thanks!

m My quadcopter has a REALLY bad PID problem. I already tried from 1.0 to 18.0 P values on pitch and roll and see NO differences. Sometimes my quadcopter reaches an altitude of like 10 meters and sometimes don't even 1 meter, even in FULL POWER And I don't even can control him beacuse of its unbalan...

lucaszanella

So... I was changing my PID values on the notebook. When I pressed write (on the xbee pro), it wrote some really crazy PID values that has nothing related to what I typed. Why did this happened? Ive always changed the AUX low high and medium and clicked "write" and it worked. And also, how...

lucaszanella

Thanks you. I will try this this week!

And about the velocity problem, you know what migth be happening? Maybe this changes are going to fix this?

Thank you so much!

lucaszanella

Yep, I already did it. In this video I posted the quadcopter is without the prop savers

lucaszanella

The PID values are default and this is the setup:

Hello, I'm pretty sure that my quadcopter can reach higher altitudes than this: m but don't know why I can't get more velocity the the motor. Here are the problems: When the quad is falling down and I give it more throttle, it sometimes don't responses and keep falling, even if I give it full thrott...

lucaszanella

One more thing: when I turn on the quadcopter (when everything was working), the 4 ESCs were activated and did some beeps. There was one of them that beeped differently from the others. When 3 finished beeping this one beeped one more time. Don't know if was the burned ESC. Can a uncalibrated ESC bu...

lucaszanella

Gonna solder the next ESC directly. But the quality of the connectors are good.

Didn't know this about hte battery. Maybe the 5000mAh can reduce the risks?
But the ESCs are not working at maxximum power, and they didn't burn while hard working, just at the motors activation, :/

Weird

lucaszanella

I'm using 18-20A Hobby King ESCs with turnigy motors that have a max current of around 7~14A. And the battery is a turnigy li-po 3S 20C 3000mAh but I also have a 5000mAh. I'm using this adaptor: m All the ESCs are equally connected to this adaptor, and the battery goes connected to it directly. The ...

lucaszanella

This is my quad: m Th fligth is unstable. One time I plugged the battery and imediately burned 1 of the 4 ESCs for no reason. Today I was flying and then turned off the motors. When I tried to turn on again no one was truning on. After so many tries, the motors turned on, but 1 ESC burned again Don'...

lucaszanella

I really tried, but didn't undesrtand what is PID and what values I have to modify to get a more stable fligth!

Any PID tutorial that I can read?
Can somebody help me?

Thanks

So here's my first fligth...

http://www.youtube.com/watch?v=oxI3o5bLXNs

Don't know why but I had to fly with max throttle... And the fligth was not so much stable.

What can I do?

lucaszanella

http://www.youtube.com/watch?v=oxI3o5bLXNs

The max altitude that it gone was at full throttle, don't know if something is wrong...

And with the go pro it din't flied!

lucaszanella

I don't understand much english.
If all my TX values are at 1500 on the GUI it shouldn't give all motors the same power?

What do you mean with trimming?

I don't understand anything about "passthrough in flight calibration" don't even know what it means

lucaszanella

m Here's my quadcopter. I'm afraid to fly Everything is calibrated but in the ground, when I give the motors throttle, one side seems to rotate stronger then other (I think the quadcopter is not perfectly balanced). If I give the motors a good throttle it will not be a problem, rigth? With him at th...

lucaszanella

I'm reading the values in the GUI and all transmitters connections are rigth, but when I move the rigth stick of my transmitter to the rigth position the motors activate

lucaszanella

What happens when the quadcopter losts the transmitter signal? I was testing with my quadcopter (motors activated) and when I turned off the Tx the quad stayed at the same velocity but after some seconds the motors speeded up so hard that I turned the Tx on again. Can someone explain me what happene...

Sometimes the GUI freezes (I think it's when he lost some bytes from the xbee pro, and that from a 1m distance). My xbees are 2 900mhz pro RP-SMA. Can I correct this issue on the GUI? When it freezes I have to close it and open again. I would like to watch at a real time the altitude of my quadcopte...

lucaszanella

Why the GUI stops while I'm watching data with xbees? Lost data? Why the GUI just don't reconnect? It gets frizzed and I have to close, so I wouldn't be able to see the altitude live on my screen. Will something change on the fly if I connect the GUI to the quad via xbee while flying? It's a problem...

lucaszanella

Hello, just finished my quadcopter and before the first fly I want to need what do I have to setup before flying. Here's my quadcopter and a link to all parts: m (I'm using 2 xbees pro to send quadcopter data wirelessy to the GUI) Already did this steps: Magnetometer and Acc calibration (I'm reading...

lucaszanella

I've just built my quadcopter, everything worked fine, all motors started rigth but when I was testing the configurations before the first fligth one of the ESCs BURNED when I connected the battery. 1 minute before the quadcopter we're ON and nothing happened!!! What could have happened? Can this ha...

lucaszanella

I've just attached all the parts together and calibrated ACC and Baro. Everything is working fine but the magnetometer is a little bit weird. When I rotate my quadcopter, the quadcopter graph on the GUI starts rotating, but when I rotate it so much he gets confused and sometimes do some weird moveme...

lucaszanella

when I give it full throttle and I see the values of motors velocity on the GUi all the motors increase their values a lot but one motor don't. Why?

lucaszanella

Don't know how but I reconnected everything back and now all the motors started. You guys know what could be the problem? Any chances of one motor stopping while flying

lucaszanella

I've just connected the motor to the other ESC and it worked. Should it be a problem with this ESC?

lucaszanella

I was setting everything up for the first time when one of the motors don't started:

Please help me

thanks!!!

lucaszanella

don't even the rx is being powered. Should I have to connect the battery to read all data?

lucaszanella

I've just selected freeimuv043 in the sketch and uploaded. In the GUI when I press start I can read the PID info but when I press start in the gyro acc baro and mag sensors it can't read. A value at I2C error starts growing.

Here are the connections https://p.twimg.com/AvhOQMfCIAAGWpK.jpg:large with warthox shield

PLEASE HELP ME

lucaszanella

If I set all these stabilizations to the AUX1 channel high, for example, what's recommended for me: Should I fly with them activated ALL TIME or should I activate them only when I want to stay at the same point with the quadcopter? I wanna know if I can fly with them always activated, and what are t...

lucaszanella

Can I connect my xbee to the tx and rx of pro mini? I'm using the warthox shield with freeimu v04 and the warthox uses the tx pin but I think the freeimu doesn't, so I can connect xbee to tx?

Thanks!

lucaszanella

I want to add a go pro in the front of my X quadcopter. Does the multiwii automatically balances itself?

Thanks!

lucaszanella

How do I add more servos to be controlled by my transmitter? Like with ch5 ch6 ch8? What is the ch7 mode for?

Thanks

lucaszanella

Thank you so much

lucaszanella

33k to ground and 55k to vcc? 10kohm from GND to analog input? The GUI displays the battery level?

Thanks

lucaszanella

Can I make my own battery monitor with resistors? Multiwii will read this? Can I see the battery level in the GUI?
In wich pin I have to plug it?
The GUI displays the altitude? Wich measure system? Foots?

To have my quadcopter 2 motors (with the inverted propellers) inverted, I have to change the polarity of the ESC-to-motor?

lucaszanella

I must use 115200? Can I don't connect the xbee rx pin to the quadcopter tx to prevent acidental clicking on something of the processing screen and stop flying?

lucaszanella

Can I use my 2 xbees pro 900mHz to see the processing screen while flying? I mean, I can set the velocity to 115200bps or the velocity needed for it, plug the xbee to pro mini rx and tx pins, and receive the data with my other xbee connected to my ftdi breakout board, then I read this with processin...
