what is the best helicopter in autorotation

[zeeoo]

Hi Slow rotor,

the weight helps to regain speed but degrades the finesse.
the best glide ratio is designed at a certain speed/weight/centering.

Talking about tip jet helicopters, the diffrene between the Hornt and the Djinn was that the Djin used cold air , the nozzles were smaller with less drag.

are you interested in that kind of design?
have you data about the djinn and the hornet ?

thanks
