Well, I had my second flight with the 4* the other night. I switched the prop to an APC 16X6 and it woke it up. I did not touch the needles on it, and it ran good. No transition issues like the first time with the MAS, temp was about the same, except lower humidity. It idled down good, a quick touch o throttle got the RPM's up and it idled down nice again during my final, so looks like I got the engine dialed in well for the next gallon or two until it is finally broken in. When I landed after a 9 minute flight, the engine was cool, as in if I touched it I wouldn't get burned. Has a little burble to it at high end, but no performance issues. I think the 4* has a 12-14 ounce tank and I used 1/4 of it for the 9 minute flight, which should relate to 30 minutes of flight to the tank. Wow! Big difference between the APC and MAS props on this plane. The MAS used much more fuel. I burned up a whole tank in 15 minutes with the MAS on. <div>
