I am a sportsman pattern flier who is tired of paying $14/gal for glo fuel and wiping off the gooey mess. It sure looks like the RCS 140 gasser will nicely replace my OS Surpass 120 with only a slight weight penalty. Any words of wisdom will be appreciated. The RCS 140 turns an APC 16X8 at 8800 RPM and gives over 15 pounds of static thrust (so they advertise). Thats a lot more than my 120 is doing.
