well something is amiss. the thing wants to tilt forward consistantly..
CG is perfect. Motors are all spinning right. props are on right..copter shows level in mission planner. Its like the rear motors are putting out too much thrust.

Sounds like a level issue, find a truly level surface and re-calibrate level, see if that helps

Did that. Still not having any luck. It continually wants to pitch forward. i can hold the stick back and it will keep level but that doesnt make for very good flying. haha

Have you tried the channel 7 auto trim option in a wind free environment?

Here's a good link that explains it, basically you hover in a wind free environment, use your controller to get the quad level in the air, engage auto trim and it'll trim it out, the name is deceiving though, there is nothing auto about it

Ok, that seems to have helped. The quad now stays level. Somewhat. Now i just have to finetune things.

Titus,

Just jumping in to say thanks... You get points for:

- PID settings - that saved me an hour of reading (which coincidentally I ended up going and reading anyway)

- 3DR PID tuning - I can't imagine how awful this would have been if I had to stop - and plug in usb...I could have done bluetooth, but with the 3DR this gives me options down the line.

- 5mm locknuts - solid tip...switching to those killed a lot of the vibes from the NTM props adapters


At this point I know it can fly, just won't have a chance to do any more flight tuning until this pesky little hurricane blows through.

Have you started messing around with waypoints yet?
