S-69 ABC Helicopter Limitations
Does anyone know what the top speed of the S-69 ABC helicopter was, in level flight without the two jets strapped to its side and what speed did (with and without the jets) would retreating blade stall and/or blade collision become a problem?

Also what is meant by rotor hinge offset?

Thanks
Obi
