Hi,A few weeks ago I finished assembling an Arducopter from jdrones, using standard AC20-1.0 ESCs and A-2830/12 850Kv motors.All the motors seem to start up evenly, but when I push throttle to about 30% it just leans to one side to the point where it would never get off the ground without destroying a propeller or two - and I'm getting stuck on troubleshooting it.I also have trouble running the motors command in CLI - all other commands work fine but 'motors' never seems to display anything on screen.I have manually calibrated the ESCs using ch3 on my Turnigy 9x receiver. They are connected to the motors with bullet connectors that I am considering removing, although I'm not convinced that has anything to do with this particular problem.My Turnigy is a Mode 1, and I have seen various reports of this needing to be changed to Mode 2, but I think that is irrelevant for now?APM seems to behave as expected, eg if i hold the copter in my hands and tilt it from side to side, I can feel the motors responding accordingly.Have tried 2.0.22 - 2.0.24beta and all do the same thing so I am fairly certain its a construction issue, but not sure how to resolve without pulling everything apart again and again. Eyeballing it, the arms and motors appear to be straight and even.I have a short video of what is happening that I will upload soon, but you can probably imagine what it looks like...Any help would be much appreciated, although not in a huge rush to get it in the air, for its first inevitable crash :)ThanksJ

I have exactly the same problems you described Jay, please keep me informed about your findings concerning these problems. Maybe you/we find the solution.
Motors is not supposed to show anything on screen. If you read the manual, it says the following:
Enter this mode, then plug-in battery, move your RC transmitter's pitch/roll sticks in each direction to make the prop in that direction spin (so moving the stick up will make the front rotor spin on a quad, and moving it right will make the right rotor spin). For copters with more than four motors, it will spin groups of motors, with the one closest to the direction of the stick going fastest.
You almost certainly have it setup wrong: either in x mode when you're flying + (or vice versa), have the APM not pointing "forward", or have a motor/prop hooked up wrong. Do the above test, and then holding the quad firmly in flight mode, try moving your stick in the various directions and see of the quad moves in that direction.
If all that checks out and you still have issues, erase/reset and do a setup again.
Check to see if your quad is in balance. It could be you need to shift your battery a bit to get it as close as possible then use trims on your radio to fine tune if needed. I normally place my right middle finger under one arm at the tip and left under the opposite then do the other two arms. That gets it pretty close. Also was it level when you pluged in the battery? Or did it get moved while initializing? These are the most likely causes.
