Start up / Shutdowns. When I first started to fly, my instructor (many 1000's hrs on type), insisted that even with frictions on, the left hand covered the collective and the cyclic was gripped between the knees, when doing checks with the right hand. It did not seem to difficult to achieve with my stature and build and maybe it won't work for everyone, but I still use that precaution today until I am ready to release frictions and fly. Certainly, it should avoid the cyclic flopping around with high rpm levels.
well....just a thought anyway
