CGB Ultimate engine choice?
Recatcher,
I have a Saito .91 with a Slimeline pitts muffler with the 70 degree pipes an Ultimate turning a 15X6 ot 14X8 APC prop for in my CGB Ultimate. It flies extremely well and I often receive comments about how nice and scale it flies. The .91 FS will not hover it or give you unlimited vertical, but it is more than enough power to fly it well. In fact, I have been thinking about putting a YS .63 in mine since that engine will turn a 13X6 APC at 11,000 RPM and is lighter than the Saito with the Slimline muffler.
