I am simply repeating that Rolls Royce were particularly pleased with the epicyclic control gear.
I would suggest if that is what Rolls Royce thought it is Probably quite good
Many thanks

Many thanks for the reply. The 2 ghost engines were combined to produce the Eagle engine
As to the gearing I believe it was to reduce the crank revolutions for the propeller
It would help if you tried to understand what the rest of us have written. As I wrote before, the Ghost engine was a cast-iron sidevalve and the Hawk (and therefore its derivative, the Eagle) was a separate-cylinder fabricated engine with overhead valves and camshafts. Those engines did not have a reduction gear, and the much later RR engines that did were not epicyclic gears. A reduction gear is not a control gear and my earlier question asked what control gear you referred to.
