Spare parts 4pcs Landing Skid Set - $4.23 and 350mah Li-Batteryh - $5.74
This kit requires some soldering and own RX and TX. I used for TX Turnigy 9xR with Frsky DJT - $51.85 radio from combo pack bought from HK, and for TX FrSky V8R4-II - $13.62 nice tiny 4 channel receiver with wide range of operating voltage 3.0~16.0V.
After soldering was done, first problem a stumbled on was that MultiWii GUI wasn't able to connect via serial port. Though solution was pretty simple. I compiled new firmware which comes with MultiWii GUI in MultiWii folder with Arduino IDE. It can be programmed with the same IDE too. I used USBasp programmer (some cheap sort of this programmer for using with avrdude and etc can be fixed using this article).
Before writing new firmware you must configure MultiWii config.h file, i found good thread on rcgroups forum about this micro quadcopter. My uncommented/changed lines (didn't test much just wanted to try, you can read a thread about this parameters on rcgroups):
#define QUADX
#define MINTHROTTLE 1000
#define MAXTHROTTLE 2000
#define DESQUARED6DOFV4
#define MPU6050
//#define I2C_SPEED 100000L
#define I2C_SPEED 400000L
#define INTERNAL_I2C_PULLUPS
#define EXT_MOTOR_RANGE
#define MOTOR_STOP
Cons in my kit motors wires were too short and i needed to extend they.
