Buy an R44, stop playing with autos and fly over good landing areas as much as possible, always fly at a good height so if or when you might be that unlucky 1 in a million that has an engine failure you have plenty of time to sort yourself out. If the horn aint screaming you raise the collective a little more. Your probably staring at the RRPM guage too much, attitude, wait assess, and in between that look for a nice flat spot. And remember if you turn a lot you have to work harder to control RRPM. Also read thread about R22s maybe coming to an end. I dont proclaim to be any good at it myself but in training there is a big emphasis on keeping the needles in the green but thats mainly to keep their aircraft in good nick, you will be glad of all that inertia in the blades at the bottom. Ive been will instructors in BiAnnuals who still balls it up after thousands of them.
Concentrate your efforts on to other things that will keep you alive longer like good planning and downwind ops, hot and heavy in that R22.
