Quad copter build for FoxtechFPV 48-22 Motor test

Disk type motor is always look fantastic for Multirotor application. The FoxtechFPV has release new series of motor for multi copter and open the section of tester for review with free motor.
I do apply for testing of disk type 48-22 690KV motor and FoxtechFPV has send me 4 of this motor for testing. The testing  is plant on early of this week but duel to the delay of the CNC cut. I just got the frame CNC today and start the build log and hope can do maiden and test fly by this weekend.
Some pics of the build log :
The motor is look like belt type motor but the base and the stator are not separated as the dt700 or dt750,... It is a solid block and make the base and the motor very strong. This will help the motor less vibration and save the bearing. These are 4 motors which are free for testing from FoxtechFPV. Thansk for this chance.

Closer look at the motors, The motor can handle difference prop type with or without the prop adapter.

I build new kit design DIY for these motor test: 

The config will be

- Carbon DIY kit 550 M2M size and carbon fiber + 16mm tail boom.

- The Boom Blocks are also my DIY  which I have in full size from  12mm, 16mm, 21.5mm and squad 10x10 , 12x12 mm.

Pics of the carbon centre base , motor base and battery tray just out of my CNC machine

The ESCs are Mystery Clound 30A which I just update Simonk Firmware
More about the firmware see here http://www.rcgroups.com/forums/showthread.php?t=1720736
The esc is not re-cover yet :-))

It will plant to fly with 3-4S 4000mah x 2 pcs with 12x38 prop from quadroufo.com
Flycontrol board will be RABIT FC with firmware version 1.220 or later firmware with all sensors, ultrasonic and GPS

Mikrokopter project

Hi, i start the project to re-built the Mikrokopter octo.
This is the second hand control board with some faulty ESCs. I have to buy the CPU with special boot loader from Mikrokopter since this 2.0 ESC is not open bootloader. Wow it cost too much for buying 2 chip atmega 168 from Mk US and shipped back to Viet Nam.
However, I finish to fix the esc and re-assembly the system. It's planed to put on my Octokopter or X8 Octo. Some pic of rebuilt electronic.
The ESC board with 8 ESCs and upgrade some more capacitors for hight power motor ( RCTimer 3536 - 700Kv with 12x6 props on 4S or MT-3515 T-motor with 15x5props on 5S)

I'm often used 2 parallel batteries for multicopter since it is easier to arrange the batteries and CG. Also the power cable is smaller and softener.  Here it is: 

 The Mk tower including: Mk Flight controler ME 2.1, Navicontrol board ver. 1.1 and Mk GPS

 All are ready for pluging on kit. Just waiting for carbon plate and kit CNC which will be next few days.

 All board including ESC have upgraded to lastest firmware via MK-Tool.

Next will be the kit CNC and assembly. I still consider to put it on large Octocopter or a smaller X8 copter.
More coming ....
