Well I am totally bummed. I guess the only thing I can do now is get a new gps cable and try that. So close but so far. I guess it is back to the KK2 board. Oh well.

Thanks @iskess. I just posted this there for those following this:


I have been working on my future arducopter for almost a month now mainly getting parts from various vendors in china, rctimer being one of them. In any case, I have run into what seems like a roadblock with the gps on this quadcopter as everything seems to be flashing pretty but nothing is registering in with ardupilot Mission Planner. I just get a "NO GPS'. So I am stumpped as to what to do with this.

I went through this great post (kudos to the author) and it helped a lot. I even did all the terminal setup reset ect.. but nothing.

I put a video up for those who have more knowledge that I do with this sort of stuff.

Any help would be much appreciated... Thanks in advance.

Hi everyone, please spare a moment to look at this post.

I'm trying to get an idea about the kind of interest the DIY community would have in consumer applications.
