Injecting life into this old thread (which I started way back)... I flew the R44 with a different instructor today, and he asked "have you ever tried flying out of SWP with lateral cyclic?" Funny really since I think it was a discussion between me and one of their now-departed instructors that got the school interested in the idea.
He said that they'd tried it and got an altitude loss of 100 feet to recover instead of 400 feet with the usual technique. We went out and flew a couple and it certainly worked. Of course this was not from fully-developed SWP, just wait for the descent to start then wait a couple of seconds.
The technique we used was right cyclic, left pedal, pull to 23" of power (max continuous).
