Recently I noted a video on youtube where a guy has an o200 in his aircraft and he does a take off and short flight and lands. Located here->https://www.youtube.com/watch?v=KP5Uu7pSmqc
I asked him about the speeds and he has indicated that they are as follows-> Propeller warp drive 70 inch with very step -2100 RPM ground - 2,750 max in flight Economic cruise cruise 200 kmh -2200 RPM 17 liters now. Maximum speed of this propeller configuration with 270 kmh Therefore I am wonder if the Corvair isnt the better choice based on Mark Landfords spec which are; # Fuel capacity: 16 gallons # Top speed: 191 mph TAS (true airspeed) with 3100cc Corvair engine and Sensenich 54x54 prop (turning almost 4000 rpm), 184 mph TAS with Sensenich 54x58 (but turning only 3400 rpm, and burning less fuel). # Fuel consumption: I get 42 mpg while flying at 160 mph TAS at 10,000' running "lean of peak", which is how I always fly at altitude. # Stall speed: 57 mph with split flaps deployed, 62 mph "clean" Based on the above wouldn't the Corvair seem to be the better choice? What is the advantage of the o200 vs the Corvair or the Corvair over the o200? What is the time between overhaul on a Corvair? Thanks Stan
