CosmoK---
Descend at climb power to achieve better cruise airspeed. Works on the DC-4 and DC-7 as well. But, oddly, not on the L-1649A Connie. Did not get to fly this model all that long as the chief pilot crashed it at SCK. Tried a short landing and tore the gear clean off.
Pigboat--
Yes indeed, same on the 532-7 powered aircraft, except that if desired, cruise at 742C altho hot section longevity is not enhanced.
