Presumeably with a teethering head if you do pull up with cyclic , maintaining rotor speed with collective ,you need to be careful at the top of climb as you push over so as not to get low g or do you just gradually reduce the airspeed in the climb to 60- 70 kts or so before the inevitable descent.?Have never tried it or seen it demonstrated .Not about to try either without instruction I hasten to add.
