Thanks for the input. It looks like Boris is correct, will need to balance the frame COG as near as possible to the marked frame centrepoint to ensure good flight characteristics. Will try this out. Cheers

Hi, I'm building a TBS discovery which appears similar to the QAV500 with spider-like arms formation. Where is the COG for iMU/GPS calibration for the WKM? It looks like the COG will change drastically when you put on the battery unless you balance the front-end with a gopro-type camera. Cheers

Hi, I've the same problem after upgrading from FW5.02 to FW5.12a. See my post here to resolve the problem. However I fly a quad with Turnigy plush 30 amp escs, http://www.multirotorforums.com/showthread.php?4831-Getting-Frustrated Cheers

Hi all I've the same problem when I upgraded to FW5.12 from FW5.02, motors 3&4 turn very slowly on CSC. When I downgraded back to FW5.02 all motors start up at the same time. In the new firmware 5.12, there's a new menu "motor idle speed" under motor mix. Increase motor idle speed to High and...

Hi, Sorry for your mishap. It's standard for WKM to have dual power line, one to the IMU and the other to the escs/motors. When upgrading firmware/adjusting gains etc we always disconnect power to the escs/motors. I've adopted the same dual power line structure to my arducopter FC for safety...

Hi, I've 2 Futaba 6028SB and they connected fine with only one cable. Unless I read incorrectly, you should not be connecting to channel 8 of the TX but to to the special Sbus connector below channel 8. Cheers

Hi You don't need an F-Sbus though it is easier as you only connect one wire for the Sbus. Goto page 16 of the manual and details on connections for non-Sbus Rx are illustrated, AETR to channel1/2/3/4 and u(control mode sw) to channel 7, X2&X3 rotary sw to channel 5/6. Your Tx channel for 5/6/7...

You should be able to program the T9X 3way switch following this tutorial from diydrones. The T9x is susceptible to drift and you should let it warmup and recheck the pulse rates before each flight. http://diydrones.com/profiles/blogs/mode-switch-setup-for-turnigy-1
