I've had good luck with the larger engines in the RCS line and would think the 140 would be a good choice. I also think the new Zenoah G26 would do a good job.
I have just received one of these planes and contacted Erick Royer who reviewed the plane for RCUniverse on a G23
He told me that the G23 was "just right" if slightly underpowered for the plane but a G26 should be excellent.
