RE: Maxair Revolution II Velox
The Saito 1.25 is weak IMO,mmaybe good for a 7lb plane but not a 9 lb. After using 4 strokes for several years,I'm back to 2-strokes for good. You can 3-D like crazy with a good 2-stroke so why throw $$$ out the window on fuel & engine? My choice: OS 1.20 AX,I have 2 now & love 'em. My Velox is getting one.
