M-91 has 285 kg empty weight and should carry 2 big guys and something else
including fuel (if necessary :). Vmax is calculated to 145 kmh, Vmin is expected
40 kmh.
Yuri Shevchenko still has some things to be upgraded in it, though he has
already moved seats 20 cm up, thrust line was lowered to 4 degrees below the
keel line. He also changed original self-made rotor to standard 27' Dragon
Wings.
Seats are simply taken from city bus - light and strong they are also cheapest
available.
