For fun, I tried the 'super slow roll challenge' yesterday. Objective is to roll as slow as possible while maintaining a constant roll rate, heading, and altitude. Not perfect and not easy!
Yep, lots of rudder! Went through a rough section after passing through inverted in trying to maintain a constant roll rate. The roll rate will naturally increase as you switch rudders after passing through inverted, which you must manage by reducing (an already miniscule) aileron input. Lots of constantly changing variables to manage. Fun challenge.
Hmm that would be a real trick for this kind of roll since unlike the positive G Hoover roll, this roll would require you to rotate the coffee cup AND the coffee pot 360 degrees as you roll. Not enough hands...
