I fly the Revmaster 2300 in my new (prototype) Thatcher CX5 two place and I love that engine. Redundant ignition and alternators and 4o years of development have made it, IMHO, an exceptional engine. It really has lots of power and runs great. I use a Zenith carb on it though because I don't trust the guillotine type carbs. I do have a very good carb heat system on it for carb ice and intake ice. I can throttle back and cruise about 95-100 mph on less than 3 gph. At normal cruise of 125 mph I use about 4.5 gph . It has 8 coils running through 4 separate systems, an oil cooler, and lots of proprietary engine parts that make it a superb engine and , unlike certified engines, it really DOEs put out it's rated horsepower. I climb 1000 fpm and it has great control response- responsive but not too sensitive. Lands at 42mph.
I simply love it. I am flying it to SunNFun in two weeks. Hope to see some of you there in the Thatcher Aircraft booth.
