It's normal for my heavy quad! :P
I asked Jason to take a look at the autotakeoff and autolanding routine.

Hello, if I have a wobble in my 3dr frame in stablize mode can this be a direct result to a bent shaft? I have ordered the 3dr motor shafts and was wondering if it will fix the wobbling or is it part of the 2.7 release?

You may have RATE P too high... try to lower it a bit. If you have bent shaft, spin the motors on the ground and put throttle to 0 and see if there's a motor stopping much quicker and not "loose" like the others. Another way is to check the motor temperature. A bent shaft will most likelly cause motor to heat more. Also spin it by hand and check if it "brakes". If the shaft is heavily bent, it will also cause more vibrations on the arm to wich is attached.

I know the shafts is bent, I went into altitude hold about 7m heigh and the quad dropped like a rock out of the air bending 3 shafts about 15 degrees.

I would first check your props are fully balanced as I had one that I thought was the shaft and ran true after prop was balanced. Made loiter better too.

Spent some time trying to setup my clone F450 with the APM2.It hovers now. But seems to have this funny wobble issue. I have been dropping the Rate P down to lower the effects of this. Currently at 0.09.
The wobble seems to cycle every one second. Almost like the quad is shivering every second or other second. Should I keep lowering the the Rate P?

I think it is probably related to I rate so you should try lowering it. Low frequency oscillations are usualy due to too high I rate. Maybe I am wrong so don't jump me.
