learned to hover at the end of my second flying season with a u can do .46 and a rossi .45.took a weeks vacation from work,was blessed with a weeks worth of good weather,and practice,practice,practice. the rossi took all the throttle management out of the equation.took full power with a 12.25x3.75 apc.entering from a downwind pop-up was easier than working it down from a higher altitude.os .70 added some power but also increased the tendancy to torque-roll.lots of time on the sim,more than i care to admit.PRACTICE MAKES PERFECT.or so i heard.my 2 cents
