You can test roll-pitch-yaw direction by holding in hand overhead.If they sense wrong then just reverse motor.Better to test one motor at a time to avoid confusing.Rear props must have label face up ie: 8X4.5 must be visible wnen looking at it.Don't forget to do FC calibration more than one time.

Ive checked realtime data and all stick inputs match with the labels in multiwiiconf.
So either the sensor is wrong, or the motors are plugged in wrong.

I have the USB connector facing forward and topside, this is how the flip is supposed to go I think?

I have AC's modified firmware (RC 2.1 r976), VTAIL4 is defined, as well as FLYDUINO_MPU.
The following picture is good for the prop rotation :

But the motor number are good only for Y4 configuration WITHOUT set YAW=-1
With this Y4 configuration, you can choose this motor configuration
OR you can set YAW=-1 in multiwii code, and leave motors as a VTAIL4 conf.

If you choose VTAIL4, the props rotation is the same, but at rear, 9 is at right, and 11 at left (always without YAW=-1)

You always have to look your multicopter from top for the rotation, even if rear motors face down.

MWC flip has MPU6050. Try using the define MPU6050 first, if that does not work, you may have to change the orientation.

Code: Select all
/* individual sensor orientation */
//#define ACC_ORIENTATION(X, Y, Z) {accADC[ROLL] = Y; accADC[PITCH] = -X; 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;}

If you follow what i said here, orientation should be USB facing front.

Don't forget to calibrate your ESCs if they can be calibrated.

Eh.. I already count... 4 cuts on my fingers. These puppies bite!
I need me a pair of these.



Found the problem though, those damn motor pin assignment pictures are wrong.
The tail motor numbers are backwards, like orphee says, 11 should be the LEFT motor, and vise versa.
So atleast I got this meatgrinder going in the right direction now. Next up is dealing with derped simonK ESCs.
Im a little hesitant to try anything with this quad, with those ESCs boiling up so badly..
All I have connected to them is battery on one end, motor on the other end, and JUST the signal wire going to the flipboard.
I dont know what im doing wrong, it has grounded BOTH my beautiful new quads, and it is absolutely maddening!

I will work out something to post on the Setup post.
The problem is that in different config, you get different motor and prop rotation...

Does the thing heat on the ground without any motor movement ?

You probably need to calibrate your ESCs...

What is your transmitter ? what is your Throttle Channel on your receiver ?

Exactly. Also in config.h: #define FLYDUINO_MPU //
that's for flip mwc version.

The power on the mini hunter is quite alright, infact I had to hold on to it for dear life when the gyro started to arm wrestle me.
The escs are simonK, so technically they shouldn't need any calibration, but I did it through the firmware so that should be alright.
It all seems to function now, though still feeling quite far off from the PID settings ill eventually need (simonK needs them slashed in half I believe).
Its just the escs getting a bit toasty.. I just set it on my desk powered and armed,
gonna see if it heats up from just sitting there in about 3 minutes.
Hope it doesn't catch fire (knocks on wood)....

Heheh its getting a little difficult to figure these things out.

Welp, on the ESC heating thing, it seems perfectly pleased with just sitting there,
its not heating up with doing nothing, so I guess the BECs are in the clear?
I really hope they just heated up because the controller was really yanking those motor throttles while I was debugging the backwards tail...
I guess ill just button this mini hunter up and start PID testing with it a bit and see if it still cooks up from just hovering.

WRONG !!!
You must calibrate each ESC with your THROTTLE chan each time you change the receiver...
The calibration needs to be done with props removed :
- ESC plugged directly the the THROTTLE chan on your receiver (not on the board)
- ESC powered off
- Transmitter with THROTTLE at full power
- Plug ESC, some beep should be done
- push THROTTLE down to min GAZ another beep is heard.

Do the calibration for each ESC.

I had issues with Multiwii firmware (#define ESC_CALIB_CANNOT_FLY) option... but maybe it works for other guys here...

I still like the - Do them one by one - thing..
i have made a little adaptor to calibrate many at once.
