cherminator Posted May 29, 2018 Report Share Posted May 29, 2018 https://en.wikipedia.org/wiki/VRT_500 (skip to 2:27) Will these ever be made available in North America? Do coaxial rotor helicopters autorotate? 2 Quote Link to comment Share on other sites More sharing options...

cherminator Posted May 29, 2018 Author Report Share Posted May 29, 2018 What would be the advantage of a coaxial setup? No tail rotor to fail or get caught in the bushes. Probably shorter in length than a tail-rotored heli too. Need less room to land and safer for people and obstacles on the ground when you get there. No tail rotor means more power available for lift. I'm guessing more maneuverable as well. 1 Quote Link to comment Share on other sites More sharing options...
Wally Posted May 29, 2018 Report Share Posted May 29, 2018 What would be the advantage of a coaxial setup? Having the rotor(s) over the cargo area increases the CG range as well. 1 Quote Link to comment Share on other sites More sharing options...
Eric Hunt Posted May 30, 2018 Report Share Posted May 30, 2018 The Kamov range is known for its lifting abilities, though its rotor head and mast is a lot more complicated than this demo model. The lower rotor works in descending airflow, so is a bit less efficient. 3 Quote Link to comment Share on other sites More sharing options...
