RE: OS 1.60FX vs OS bgx-1 3500
Yeah mine has a bisson pitts on it also. I can sure understand using it in a warbird for nose weight. It sounds like the 1.60FX will do everything the BGX will. Except spin a bigger prop at lower rpm and the 1.60FX can more then make up for that. I know it will spin a APC18X10 at 8,500k giving good speed on my P-51. It also uses less fuel and weighs less. At this point i just don't see a need to ever buy another.
