Here the diagram of the KKmulticontroller board (Jakub version) successfully tested on my QRO v6:

The original ATMEGA 48 on the Jakub board must be replaced by an ATMEGA 168-20PU to load the XXcontroller_KR_1_4a firmware.

Below some various KKmulticontrollers which also works very well on the QRO v6 with the same firmware XXcontroller_KR_1_4a :
- This is the KKmulticontroller from Jakub which uses three boards from HK401 Gyros, the original Atmega 48 have been replaced by an Atmega 168 and the firmware XXcontroller_KR_1_4a have been installed:
- This is my home made KKmulticontroller v7 with an Atmega 168. I use three piezo gyro NEC Tokin ENC-03 ( piezos board from HK401 gyros will work too).
- Of course, the KKmulticontroller from Minsoo Kim works well...

Hello Chris Cashmore,

Thanks for your comments, here the QRO v6 specs loaded with the GoPro HD camera on board:

Take Off weight: 1062 g (Lipo 3S 2650mAh Turnigy rated for 40-50C with GoPro HD camera)
The Avg Power required to hover at 2 m AGL : 180 Watts
This gives a Power/Weight ratio of 168 W/Kg about 4.5 A peak / motor

Flight time about 9 min

I have previously used Lipo 3S EVO25 2550 mAh rated for 25C, today, I prefer strongly to use Lipo 3S 2650mAh Turnigy rated for 40-50C.

Below the tests results with the Lipo EVO 25:

Regards, Jean-Louis

Very nice indeed!

What kind of total flight time do you get with this setup (with an average speed, not full throttle)? And... What is the total weight of the quad with camera?

Thanks.. Keep up the good work.

Nice video!! I have those motors and ESC, really cheap for the permormance!!!! The best decision I have made :D!

Im designing a CF frame that will look like the MD4 on the arms and motors mounts. The advantage of CF tube on the arms is drag reduction! I wiil be posting my design ASAFinished! If someone knows where I can get a foam with the golfball texture ( Dimples ) please let me know! ;) Im planning to use it on the prop coverage area of the arms to increase laminar flow.

Jean Louis, I like a lot your setup! High performance simple setup! keep it up!
