what is a slow bunt over please ?
It was written , Slow speed bunt over.
This can happen at SLOW SPEEDS, when the pilot puts on a lot of power and forward stick, or in a zoom climb, when you reach the top and stick forward with power on to increase speed.
Both of these maneuvers can cause your gyro to tumble with total loss of control.
ALL pusher type gyros are able to accomplish this no matter what the thrust line is or tail configuration.
H-stab in the prop wash is a bit more forgiving but not enough to save your life.
H-stab below the prop wash is not as efficient and has a smaller envelope of safety.
A high thrust line is more sensitive to a bunt over because the nose lowers with power.
CLT is more forgiving, but can still do it.
LTL raises the nose with power and an unskilled pilot will compensate by pushing the stick forward while under full power and tumble the machine.
So, again, every machine has a definite and unique envelope of safety that should be known by the pilot.
I guess my post does not address how tall the tail should be, but any tail designed properly would work.
