I'm quite a new for NAZA-M LITE. I've not yet skimmed all the threads but let me take your time to solve my question. Just bought NAZA-M Lite and wired all the necessary peripherals like receiver, ESCs, ... I turned on the transmitter, Futaba T14SG, and power to the flyer and checked the bind Tx and Rx is OK. But, the LED on the VU of NAZA-M shows different than the sequence shown in the manual. My unit shows the green flash only 3 times while the instruction shows that it should be 4 times. However, my unit still can not be connected to my PC via USB. I tried Windows 7 64bit machine and Windows XP machine both along with the installation instruction. Is the connection with PC is the things to do first? Otherwise, the LED pattern showing my unit can not become correct?:upset::dejection:
