RE: Saito 72 -vs- YS .63
Hmmmmmm....
I wonder what the thrust figures would be for those numbers ?
As someone mentioned they are all great eninges.
Buying a NIB Saito .91 for $190 here at RCU probably beats them all hands down

You are correct about the props but... The YS is turning that 14x4 @ 11, 500k whereas the Saito will probably turn the 15x4 @ 10k.

RE: Saito 72 -vs- YS .63
After half a gallon of Powermaster YS 20/20 through it, my YS 63S currently peaks out at 11.9K rpm swinging a Graupner 12x7 prop, so I set my ground rpm at 11.5K (400 rpm on the rich side):
The engine (mounted inverted) can now hold a steady, reliable idle between 1700 and 1900 rpm without onboard glow or glow igniter, as can be seen in this video:

It's all about tuning, folks.
