I might get bigger wires later, I just used some other wires I had laying around but I don't have anything bigger at the moment. You'll have to dumb the rest of that down a bit for someone who hasn't gotten into his engineering classes quite yet in college haha. Rethinking about that rig you...

I believe it was just the 2 year old thin wires that couldn't handle the voltage. I hadn't change anything it just sparked and burned the wires. I tested the MPU and the RF receiver on 2 other Arduinos and they are definitely ruined and they are too small and integrated to find where it burned...

Well I can confirm that my MPU 6050 gyro sensor and RF receiver is fried. I ordered new ones on amazon and they will be here Saturday. Until then I guess I'm done testing..

I've watched all of those videos... I don't have the money to buy the Xbee stuff and I can't use that rig because my quadcaopter is a x shape not a + shape.

Under the first inspection, it seems it caused a power surge and didn't fry the Arduino but just the 3.3v components connected to it.... which is everything... the MPU 6050 and the RF receiver. wonderful. No more testing for a while but here is a video before all Hell broke loose tonight. :(

I mean fixed it as in successfully implementing the PID into my code. I got one test flight before something unrelated when terribly wrong. I was plugging in the Arduino for the second test and sparks flew at the power connector and destroyed the connection to the ground cable. Here is a...

And In saying that, I think I just fixed the PID to work! Time to reassemble and test before it gets to late!

I'm still trying to sort out this PID stuff. I'm still not getting the right values. I might just test it using my own algorithm because I'm so pissed off at this PID stuff.

I haven't ever used a raspberry pi but i've heard its very compatible with an arduino.

Well I managed to calibrate all of the motors to the same throttle values so that may have fixed some stability issues. I will know when I test the quad in a couple hours.

It's hard sifting through the ardupilot code. I actually can't find the .ino file to start looking. I've been programming for like 7 years but I've only been using Arduinos for like a year. This is my first actual project with an Arduino. I'll keep looking in the Ardupilot code to see its PID...

Though I could help Ethylene in giving insight to what I have done, I still need help with my problems that this thread is about :( . I'm going to try to get the PID to work but I'd to also know the answers to the questions I stated above.

I read your post, it looks like you are in the same situation as I was in a month ago. I don't believe I have a barometer on mine. PID is the most popular way that quads stabilize the motors. It runs your gyro input through some algorithms and output a throttle ( theoretically because I can't...

Thanks for your reply, I'm sorry it took this long for my response. I do apologize for not explaining what gryo sensor I'm using. I'm currently using the MPU 6050 6-axis gryo/accelerometer that uses the "kalman filter" to combine the gyro and the accelerometer into one stable reading for each...

Hello all, Brand new to this quadcopter stuff. I've build a 450 quad using an Arduino Uno as the flight controller. Though the arduino has a PID library ( don't really understand how to integrate it into my code ), I am trying to code my own flight stabilizing algorithm but can't get it...

It was getting a little warmer than the other motors when I was testing. That's got conforming that I need to replace it.

I'll probably change the motor tonight and then install the new one Friday and have the monster hovering (while tethered) Saturday. Thanks for all the help.

Well I'm getting a new ESC and motor in the mail Friday. I'll just replace the motor when I get it So I don't have to worry.

So if it's had an overload but still runs is it okay to keep or do I need to replace it? Sorry I'm a novice to electronics, I'm trying to learn as I build.

So are you saying that if the black doesn't rub off of the copper windings then it will be fine? Pardon my bad pictures.
