Jim Ryan of Cincinnati, OH desided he wanted to try something different, so he designed and made a counter rotating helicopter, the with rotor blades intermeshing. Both heads use a 5 degree coning angle, and a Beast X coupled with a Digi’Mix 3 for stabilization. Jim has 4 test flights on this machine, and it should be ready for a fuselage soon. Best of luck Jim with this very ambitious project.
