Tutorial #1 - "Bobbing" on climb until A/P disengages

Hey Everyone,

Love the NGX and am slowly learning.

I'm following Tutorial #1 to the letter (I think) and just after I engage the A/P, the nose begins to bob up and down rapidly. I'm not sure if the A/P disconnects eventually due to this or if it's because I gently try to stabilize the nose (likely the latter, huh? ).

I generally try to figure things out myself but this has happened all three times I've done the tutorial, and I'm gettinmg nowhere on my own.

Thoughts?

Thanks in advance!

Oooops .. I am missing one step in the tutorial. It involves pressing the inHG/hPa button on the Integrated Standby Flight Display to switch to hectopascals. I can find it! :)
