@Wayne, so I would need that jumper in order to power it like I would the kk2 board correct? Sorry if I sound like a newbie... I am! Where could I get such a jumper?

Comment by mark on July 23, 2013 at 8:30pm

Thanks @Wayne. Man, I really want to get this thing set up! More tomorrow. Thanks all!

@Mark -

APM 2.5 has a two buss system for power. If you use the 3DR power module, it can power the receiver and APM. There is a jumper you can install and power the entire system from one of the ESCs. Check the setup stuff on the APM.

Yeah I just tried the reset button, and loaded in everything again.. still nothing. I'll get it, just really frustrating... I will say I am super excited about getting this all to work. My next problem seems to be the electrical which for whatever reason doesnt seem to take the power from the ESCs... oh well... one step at a time. Thanks for the response. Any help is totally welcome ;) ---cheers all.

I had a similar thing happen where the GPS wasn't bring seen. I swapped out with another GPS and that didn't help, so I knew it was a software issue. I saved my parameters, reset the APM, reloaded the parameters and everything worked again.
I'll never know what happened.

Hi all,


I am installing arducopter 3.02 from the mission planner via usb...that all works really well. What is interesting is that I can't get the GPS to work (or register) in Mission Planner. So I just get a "No GPS" in the right corner. I am using the 433Mhz ArduFlyer UAV GPS Flight Control System'

I got this to work when I installed it originally a few days ago. It just worked right off the bat. Then I realized that the cables werent soldered very well so I put them together tighter. So now, it GPS lights up, the boards shows that it is 'alive' but nothing seems to register.

I really want to get this going and after sinking a ton of time in to this I am flustered as to what I should do. Anyway, any help/advice would be totally appreciated.

Best to all,

@Dan Barreiro - Yes, try following that link. It should work although it is a little over-detailed. I don't know where this would be in the discussion board.

Comment by Dan Barreiro on July 18, 2013 at 6:03am

Wayne Morris- I just reposted this in the discussion board, and just saw your comment. Can we continue there? I still don't have a grasp of what's going on, how to even start.

So your saying to follow this link verbatim and it should work? I didn't actually read through it after I saw it was for Ardupilot.

Can we continue on the discussion forum?

Thanks everyone.

@Dan Barreiro  - Arudupilot - Arducopter is the same thing. You can use the video. You basically setup three modes using the three position switch. Then you program an offset mix on the two position switch. The offset just moves the signal down to the next position for each of the three position switch settings.

On the flight mode screen adjust the end points using just the three postion switch to get flight modes 1, 3, and 5. Then turn on the second switch and adjust the offset to get positions 2, 4, and 6.

Hi all,

I'm setting up a quad (SteadiDrone) with ArduCopter and a 9ch Tx (JRx-9303).

Everything is up and running, but I'm having a hard time finding a guide on assigning switches in Mission Planner from being all "stabilized" to Stabilize, Acro, Alt hold, Loiter, Simple, RTL.

Like in this video I found here...

Here are my switches as it stands:

I thought this would help, but that's Ardupilot, not Arducopter right?

Thanks in advance guys for any help :)
