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

@Mark, if you look at the board with the motor outputs facing you, Just above the motor outputs is a two pin jumper. I don't know if you put the header in or not. This bridges the ESC power side to the rest of the board. I went to look at the rctimer site and their photos has the header and jumper included and the board shows the connection as JP1.

My GPS does not get satellite GPS lock indoors. The No GPS on the planner means you don't have lock. The GPS maybe working fine but you can't lock inside. Take it outside and wait several minutes. The GPS should find the satellites and you will then see GPS lock on the MP.

@Oliver  thanks buddy I appreciate that info. Always learning :-)

@John McGarth

John, if the hex isn't level on the ground or if it has been rotated after arming the motors may spool up quite differently from one another as the craft is trying to orient itself, very noticeable if you are applying only a little throttle. The test is to spool up to where the hex is light on its feet, or even just lifts off. If there is indeed a problem you'll know it then. I got spooked by the same thing early on.

Ok just brought the Hex into the shop hooked everything up again to diagnose issue and the motor works 100% i tapped on the esc etc etc.. seems to work fine.. A possible glicth with the apm? Interesting.

Need a little help here. I have a month old Hexa from 3Dr. I was testing my gimbal this morning and when I when to launch one of the motors was not spinning much should I look at the motor going out or esc?  A month old not good at all.

Hi Wayne, Bill, et al,

I just uploaded a video of my setup and apparent problem.

https://www.youtube.com/watch?v=beOt-r2cU7s

I am really excited to get this thing in the air. I believe it has all the components... but I must be not doing something correctly.

Any advice/ suggestions are more than welcome.

Thanks to all viewers,

mark

Mark, if you have the power module, you don't need the jumper. If you don't use the power module you can use the jumper. It should have some with the APM controller. It is a small black square. This is a jumper like is used on a hard drive and other electronics to select options.

Look at this link to see the options on powering.

Mark,
When I said do a "reset" I don't mean hit the reset button, I meant via CLI, type in 'SETUP', 'RESET' and it wipes your board clean back to factory defaults. Then I loaded my parameters, then my GPS started working. I have no idea if this is your problem, but I had the same symptom and that's how I got it working again.
