BigWave,
Set the pitch on the bottom as close to what you have in your upright top point. For some reason the Venture will be a dog with 9.5 degrees on the bench. I would make these typical settins that are fine on most birds but then find that I would have to change my pitch curve setting substantially to get a respectable climbout.

So, if you have +11 on top then try to set the ID1 at -11. After you spend sometime inverted and do inverted climbouts you can determine if it is correct.

But yes, dont make your ID1 & ID2 different at this stage of your progress. If they are different and you don't flip the position to the one you want then you could do what HelicopterHead did.

It's just one more thing to worry about when you are learning new stuff. Also, try to develop a habit of flipping to idle up when you leave the ground or whatever you remember. It seems to be a "right of passage" for burgeoning heli pilots to watch their headspeed disappear one day when they flip her over. And the dreaded feeling of "oh no, wrong mode!"
