I am about to start building my Sopwith Camel which arrived today and have considered the Saito 91/100 or YS110 but am also considering using an RCV90SP as it would fit perfectly within the cowl and swing a scale prop with the 2:1 reduction gearing - any comments out there on this installation?
The YS 110 would be far too much. This is a WW1 biplane not a pylon racer

. I would think the RCV90SP is a very good choice. or any nice 80 size four stroke
