After taking my MWC MultiWii SE V2 controller out of one of my quadcopters, I realized that I’m still running on the MultiWii 2.0 firmware, and 2.1 has been out for a while. So I downloaded the new firmware and set up the code, but then when I uploaded it to the board it said: programmer is not responding. After doing some reading, it appears that the problem is the board I’m using, not the FTDI programer. So I uploaded the firmware on to another board and it worked with no problems at all. So from now on, the “red” MWC controller is going to be my main board. It seems more reliable and it also has a 3 and 5 volt output that can be used for LEDs.

Here’s a link to the red one
