- Jim practising advanced 300Rotor RPM take offs yesterday at our home airfield Wolverhampton EGBO before starting the handover to other instructors that will also teach 300rrpm short field take offs. Started on Runway 22 wind 210/15kts then from Heli NE and Triangle ..Thanks to the ATC team.
I have never ever seen anyone touch down that Soft, and repeatedly.
That was phenomenal !
Outstanding maneuvering skill !!!
Amazing flying Jim, can't wait to have a go myself!
Nice demo, Jim.
Lovely flying, such polished landings. Looks so effortless! ;
Fabuloso !!!
100 rotor RPM takeoff IS advanced, 300 RPM is pure fun!! :) :)
Any reason why 300 rpm pre-rotation take offs, minus the quick lift off, shouldn't be standard? It would remove rotor rpm management/increase from the pilot's do to list during take off roll. Given 43% of all gyro accidents are during take off, a simplified take off procedure may help reduce that.
I'm no expert but I believe the answer is that higher take off rotor rpm increases the wear and tear on the pre-rotator mechanism. So if you don't need to, it's better for the aircraft to allow your forward speed to increase the rotor to takeoff speed.
The Sportcopter M2 can do routine 300rpm take offs
Can the pre-rotator spin the rotor that fast? What about a jump takeoff is that possible at a higher rotor speed?
Hello Ron, yes some can - and it all depends on the flight RRPM for that aircraft/load/conditions. Good "Jump" takeoff usually needs more power to the rotor than most pre-rotators offer, collective pitch control, and (usually) extra weight in the rotor tips to store the extra energy needed.

Set low pitch, spin up to the max, disconnect pre-rotator & crank up the pitch.
