I saw where Sport Pilot called Fox today and posted on the Fox thread that they won't be making engines any time soon unless demand improves. I thought it was worth noting that the lady he spoke with said they were aware of other engine makers cutting back too or not making any. I guess it goes back to what we were saying about electric and gas (big and small) taking over. I think you can get gas versions down to .46 size now but pricey. But again, they're still competing with electric and electric motors have really come down in price. I'm hard headed and stubborn so I still like my glow engines.
