Crow hop training might be safely done on a slower lighter and more forgiving plane. Not a KR. All new airplane designs seem to go through taxi tests. Even the latest ones. Im afraid homebuilders need to learn how to do that safely. Slowly build up speed and never go beyond 80% expected stall speed seem to be the most common advice. > John Bouyea/ N5391M/ OR81, just 25 nm away from KMMV... > > -----Original Message----- > From: KRnet [mailto:krnet-bounces at list.krnet.org] On Behalf Of Jeff Scott > via KRnet > Sent: Wednesday, February 04, 2015 8:20 AM > To: krnet at list.krnet.org > Subject: Re: KR> taxi testing > > > > > > > >>Do your high-speed taxi training after your plane has flown with a > "genius" pilot. > > > > > > > > > > Mark; > > Very thoughtful response.
