Arducopter first tests and questions

Hi,

I did two successful test flights with RC_01.
It seems all is set correctly. Behavior is as expected (very sensible, but I like that).

Now the questions :
- one ESC does not work (broken ? It does not output any voltage on the motor side; BEC is good instead at 5V). I exchanged it with one laying around. It works, but I prefer to have all ESC the same type. Unfortunately the original is out of stock. Is the one showed on the pictures (Turnigy, probably the same) a recommended substitute ?

- during the flights I had some issues, with motors suddenly stopping (and copter diving :( ; fortunately I was expecting some issue and then flying very low, so no damage). 
What is going wrong ? 
I noticed that there is another ESC which does not work properly, sometime stopping to work (?!). 
I already found a bad solder on a motor connector. I have then to check for them all, but in this case I would prefer to solder my connections myself from start, not having to check for bad solder joints ... or experiencing them during a flight ...

- is NG firmware already flyable, assuming it is a beta (alfa ?) revision ?

This is a starting point.
I have some other questions about stabilization etc, but I would like to check all that better, with flight experience, before asking.

Out of curiosity, 10 minutes of hovering are 2220mAh consumption from a 3300 3S lipo.

Best regards,

Ric

Hi,

Has anyone successfully for a red light on (GPS lock) with the latest NG code and a EM406 in NMEA mode at 38400 baud??

Using Sirf i can see i have a 3dfix and a good number of satelites.

The Red led on the EM406 is flashing but no GPS lock red light on oilpan.

Any suggestions anyone??

Regards,

Tony

Antonio,

sorry, I don't have any useful answer. Anyway EM406 led flashing is a little strange to me. I used it a lot with Ardupilot and UavDevBoard and know that it is bright when in original setup and very dim when it is programmed in binary from Ardpilot or UavDevBoard. Mine is just broken, don't know why.

I don't think we've tested the EM406. We recommend more modern GPS modules such as the MediaTek and uBlox. On fixed wing the EM406 can work well, but it's not a good choice for quads due to poor altitude accuracy and slow refrersh rate,

Hello

I  currently assemble my Arducopter n°115 and I found that bad weldings.

Warning, it can be very dangerous for the first tests.

Can you go up information to Arducopter team.

Regard
