I wonder if some of you might be able to help. I've just finished building my quad using the arducopter kit. I've taken my time building as I want it to be right, and made sure to read every bit of the wiki. Loaded the most recent Ardupirates NG code. Calibrated the ESCs, run the configurator, carried out all the tests and to all intents and purposes everything checks out fine. I took if outside for it's first flight last night, powered up, checked all the leds to make sure I was in stable mode - it wouldn't take off. In fact it was acting very strangely. When I armed the motors they would all tick over - seemed fine. Disarm and arm again - now they won't tick over. Strange I thought, should it not be consistant ? Different results every time I arm the motors. When I throttle up sometimes two motors will stop working, sometimes they won't. Throughout the entire test the motor throttle would never rise to takeoff point. Different results everytime !
I switched to acro mode and to all intents and purposes it works perfectly in this mode. I didn't actually let it take off for fear of breaking it on it's first flight (I haven't flown a heli in 10 years and back then I only ever was at beginner status) I did however hold it over my head and throttle up, it definitely wanted to fly and the gyros and accelerometers all seemed to be doing their job.
So the problem seems to be just in stable mode. I tried reloading the code. I get the same effect.
Could anyone suggest to me where the problem might lie ? Am I missing something very basic ?
Any help will be much appreciated
Going to check that out and get back to you.
I'm using the leds on the APM to let me know which mode I'm in. If the mode switch is reversed it shouldn't make a difference ?
I'm using the latest Ardupirates NG Rev 527
When I'm in acro mode just the green led is lit.
In stable the green led and the orange led are lit. The red is also flashing to indicate that the gps is not being recorded. I've tried it with and without gps. No difference. I also have a sonar mounted but I have disconnected it.
Okay. Might be getting closer to an answer.
When in acro mode my green led is staying on constantly. When I flip on stable the orange led comes on and stays on.
My dip switch settings are 1 down 2 3 & 4 up. Now when I look at the mode switches in the wiki
I wonder am I perhaps confusing the lights and instead of switching to stable, I'm actually putting on altitude hold. I've never observed the green led to blink at any stage. This would lead me to believe that I've never been in stable.
Sorry guys. I'm a bit confused.
Okay guys. It turns out I'm an idiot. Think I have it sorted now. I appear to have always been in stable mode.
What I failed to notice was that after arming the engines the green led starts to blink slowly. My observations were always before I armed up. Therefore I was always in stable mode and when I thought I was going to stable I was actually enabling altitude hold.
Sorry for the confusion and thanks for your help
