Haven't watched it yet but spent a lot of time teaching people to fly them.. Not permitted for Initial training after about 1962. , They had lot's of differential aileron, no brakes no electrics. Pretty Basic and underpowered. Used to go X Country plenty of times. Mostly did 3 pointers. Today hardly anyone does. There's over 100 still flying. 78 knots cruise. Automatic slats on upper Mainplanes. Should be "locked" for aeros or on ground.. . My 2nd endorsement. DH82A. Flown the all wood Gypsy As well. with the motor the valves uppermost and open so you see them.. Nev
