Yeah G-G, it sure does look like a case of "can't beat 'em - join 'em".. ..as for better, if by bigger.. no it was not better..
& again R-R stuck with their simplistic conservative approach, missing the subtle sophistications which the Sabre used,
I.E. the crankshaft coupling spur gear/simultaneous firing harmonics pitfall - was avoided in the superficially similar Napier.
The Sabre ran so smoothly that the later marks deleted the full crankshaft counterbalance set up..
.. whereas the Eagle required crank harmonics-quelling add-ons.
Sorry - I don't have any specifics on the reasons for choice of Corliss throttle in this machine ..
.. perhaps there is something on the matter in R-R heritage archives? A Hooker innovation?
Member Wuzak seems to have a fair sort of data set on R-R stuff, perhaps he knows?
There were unfulfilled plans for Chrysler corp to build Sabres to fit Bell made Hawkers at one stage,
& no doubt those Mopar production engineers would've sorted out a viable mill, & likely fit a turbo, too.
