Re: Drifting pitch

I had this exact same problem and its your sensor orientation. The orientation changed between V1.9 and V2.0. I use a BMA180 instead of a nunchuck and I just had to rotate this 90 degrees.

Re: What do I have to setup before first fly?

Just watched your GUI vid on youtube. I would disable all your modes (level, baro, mag) first and see what your motor values do. If you have baro and level enabled, then your quad will be trying to level out and trying to keep your quad at the same height all the time - you need to play around with ...

Re: What do I have to setup before first fly?

You need to make sure all your motors values are responding as close to each other as possible - otherwise - when you fly your quad it will fly off in the direction of the weak motor - if it flies at all. This is a very good link to have a read through. http://www.multiwiicopter.com/pages/multiwiico...

Re: strange re-zeroing level pitch and roll signal

Check the level indicators in the gui - pitch your quad by hand and hold it there - if the pitch indicator moves back to level, you need to check your sensor orientation. I had the same thing after I switched from V1.7 to V2.0 software.

You need a rx with ppm output. The one that comes as standard dosent have that ability. You could use the ppm encoder available from DIY Drone`s store.
