Yeah, I had that combo. While it flew fine and sounded great, it's really not the right engine for the Sukhoi. On 30% nitro I could do most scale manuovers okay, but vertical suffered. I eventually replace the Saito with an OS 160 and to quote Austin Powers,"YEA BABY". While it didn't sound the same performance was incredible. I was able to balance the plane with both engines by just moving the battery pack around. I sold it to a buddy who is a Sukhoi fanatic and I am really starting to miss it.
