I have installed my first gasser on a China Model Products FW-190. The plane weighs in at 13.25lbs. The Toro thin cast 25cc is turning a Master Airscrew 16x8 three blade @7100 rpm. Magneto ignition, stock steel muffler with 2 additional 7/16" holes in the bottom. Walbro 11mm carb. The motor flys this plane great. Good speed but limited vertical. Idles @ 1600 rpm with very smooth transition.
I know I am loading the motor down a bit. It ran 8600rpm with a APC 16x8 2 blade no problem. The lower RPM seems to be much quieter. I consider this a most successful journey. Thanks for all you help guys!!
