Standard PID works fine for me for auto leveling.. Only when I do some fast movements it wobble's a bit.. Might change my PID settings as well.

It's surprising how that I had them at 10 and I did not even have any fast wobble.
I am going to set the orientation is right I guess.

We should ask an admin to create a sub-forum only for MultiWii so we could have different threads like safety, how-to, problem, "look at me, i'm flyin' ", etc...

But that will not happen

I am using the bluewonder motor for my quad

It is nice motor, leight and very efficient with a 8x4 prop. ~5A for 400gr

But I do not recommend it for the multi plateform!!!
The wires are too fragile !!!! When you plug.. unplug... or when the wire hit the ground at landing, it used to break where you have soldered the connector

Five time I had to resolder it.

Just put a tie-wrap right after the motor to keep them from moving and you will never have any problem..

Using those a lot and they are real nice.

I had a lot of them on my planes. I already is use the tie wrap. The problem is where the bullet connector is solder.

I solder my motor direct.. Less weight. and no more problem.

DiaLFonZo-Copter MiniControl


Hi All,

Just did first testing on my MiniControl.
MPU6050

Here is a video of it Gyro only flight:
Multiwii_2.0_preversion4

DiaLFonZo-Copter Crazy2Fly MiniControl Gyro Only (1 min 39 sec)


I have a hard time to setup the ACC mode..
It woble a lot and i can't find the right setting (PID) to have it stable.

Anyone have background with the MPU that can help me ?

Code for the board:

Code:
#if defined(DiaLFonZo_Mini)
  #define MPU6050
  #define ACC_ORIENTATION(X, Y, Z)  {accADC[ROLL]  = -X; accADC[PITCH]  = -Y; accADC[YAW]  =  Z;}
  #define GYRO_ORIENTATION(X, Y, Z) {gyroADC[ROLL] =  Y; gyroADC[PITCH] = -X; gyroADC[YAW] = -Z;}
  #define MAG_ORIENTATION(X, Y, Z)  {magADC[ROLL]  =  X; magADC[PITCH]  =  Y; magADC[YAW]  = -Z;}
  #define MPU6050_ADDRESS 0xD2
  #undef INTERNAL_I2C_PULLUPS
#endif

I've had similar issues with acc mode and v2 pre 4 so I'll be watching this one.

compass wiring


So, i now have the HMC5883L compass module and, how do i wire it up ? =P

i have my current setup like this,



shall it have 3 or 5 v ? after that i think its only to solder it to the same sda and scl as the rest right ?

slow left yaw


I finally had what I would consider a successful flight!
However, I have a slow left (ccw viewed from top) yaw. I have to constantly give it right "rudder". I tried using the trim on the tx, but I have to trim it so far right that I am no longer able to arm/disarm the motors.
Other than that, it's kind of like learning to fly heli's all over again Very different feel to it. But, I will likely build more in the future

3v is correct and pick up slc/ sda/ gnd.
Mine is mounted sensor on top wires aft. I had to use alternative sensor orientation in code and put a - in front of z. See a pic @ multiwii forum.

You can overcome that by putting ARM on one of the AUX channels and arming with a switch.
