This can switch flight modes (acro, gyro stabilzation and alt hold) from a switch on your transmitter right

And is this better than the KK2.15 in any way. Like in processing power, stabilization... Thanks in advance!! ☺*☻*

Heel! How I connect in ppm with a frsky D4R-II to this FC? I also enabled this line: #define SERIAL_SUM_PPM ROLL,PITCH,THROTTLE,YAW,AUX1,AUX2,AUX3,AUX4 What is missing? target=_blank>ppm

The multiWii is the toughest FC to set up. If you have gone through all your options correctly, and enabled PPM as you did it should work, remember you must use a jumper on the D4r-ii in order fo it to put out PPM. Double check that.

I'm on Tricopter. Maybe the problem is the Yaw digital servo. I tested quadcopter fw and no problem

yeah that may very well be the issue, I am not sure if the board supports servos or not, it may need to be modified, I have seen a forum thread where it adresses that issue I just am not sure where it was. RCgroups may have the answer

hi there i need advice on adding external compass,i have removed the original compass chip from the board to enable me to connect my new external compass using the i2c connector but when i open the gui and move the board all the sensors work including the compass,surely the compass shouldnt work as there is no chip on the board, when i connect external compass and move it the compass in the gui dosent move but when i move the board again the compass works this is really baffling me any suggestions appreciated .

I use a 3A UBEC on my vtail. My question.... Can this board handle 6V? Or should I just stay with 5V output?

Great Little board. These are the parameters you will need in your sketch for 2.1 - def.h - #if defined(HK_MultiWii_SE_V2 ) #define MPU6050 #define HMC5883 #define BMP085 #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_EN_I2C_BYPASS // MAG connected to the AUX I2C bus of MPU6050 #undef INTERNAL_I2C_PULLUPS #endif - config.h - #define HK_MultiWii_SE_V2 // with MPU6050 HMC5883L BMP085

Great product working fine so far. Updated the board with the files from _shared where support for the card was added and made the setup really easy.

The 0.03 hectopascal maximum resolution of the BMP085 is an optimum enabling the sensor to respond to differences in altitude of 25 cm.

At this days pressure sensors have ~ 10cm. altitude sensitivity!
