How long to learn to hover?
Hal,
Hovering is an art... and science. I'm still honing my hovering skills after several years of bashing fun fly airplanes (that doesn't include all the flying since the mid eighties). Absolute control is key. Hanging on the prop for 10 or 20 seconds is one thing... it's entirely different to play the plane like a marionette.
Good luck Hal. Burn lots of fuel practicing.. lots. I bought 4 cases of fuel recently; I hope that's enough for the rest of the season.
Yours,
Juhan
