Shawn,
It is pretty straight forward. The first rule is keep the pedals centered. Attempting to use the pedals may cause the flap stops to be contacted. Raise the collective slightly while adding forward cyclic. One instructor told me to rock the aircraft fore and aft with the cyclic. This will get the aircraft moving. With the cyclic slightly forward the aircraft can be steered using lateral cyclic. I hope this helps. My experience in the Boeing is limited. Hopefully, an experienced tandem pilot can add additional information.
