Ain't it the truth!
My Sanye .52 four-strokes ran much like the old OS .52 Surpass engines that I had. Which happened to be great. Granted, it took a bit of a break-in to get it there. You had to be patient.
My Magnum .30 four-strokes were lucky to stay running at 3,000 rpm, whereas my OS FS-20 four-stroke engine would idle reliably at 2k rpm on 5% nitro fuel.
