I can confirm that bluetack on the nose can dramatically improve stability and control and gives the copter a tendancy to move forwards in the direction it is facing. Coupled with the precise up and down control, I'm confident that once the correct amount of bluetack has been isolated, I will be able to launch the copter from the coffee table, fly it up the stairs and land it on my bed.
