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

Hi,

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. http://diydrones.com/forum/topics/guaging-diy-community-interest-in...

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

no gps and gps lock are two completely different messages when the apm doesnt see it attached you get no gps or when your not connected to the apm mavlink protocol

when you are connected to the apm and have no lock it will read GPS: No Fix
