Hey all, So after a day of flying, everything went well, this morning I power up CS* and all the LED's are flashing at me...they flash once long, and once short. I tried to find out what this means on MK website, but couldn't find the answer...The copter still calibrates and I flew it just to check it out...flies fine but its nerve-wracking knowing something isn't right and its trying to tell me. I tried to hook up MKtool, but the thing seems to work about 10% of the time. I'm not sure what I'm doing wrong, and I have the same experience when I try to connect to Radian. I'm not a PC guy, but I bought a PC a while back for MKtool and Radian, but they both only seems to work if its a thursday with a full moon during leap year. So, my two part question is: Anyone know what the one long, one short flash means? And is there a specific order to follow when trying to hook up MKtool or Radian? Oooh, I tried to hook up one more time before hitting 'Create Thread', and MKtool opened. It says NO ERROR in green on the front page. Not sure how to run a full diagnostic... Any help is always appreciated...thank you!
