We have received several reports from users noting a "problem" in that they cannot achieve 2700 RPM, even 2400 or 2500 RPM on the ground during take off.

This, of course, is NOT a problem or a bug, and the Archer is realistic in this regard. About all you will see is around 2300 RPM on takeoff.

The Archer is neither powered by a jet engine nor equipped with a constant speed (variable pitch) propeller. In the real Archer or similar aircraft, RPMs will not increase until you are airborne. After takeoff, and once RPMs increase under speed, you should throttle back to maintain 2500 RPM or less.

Also, when departing airports that are at a field elevation or density altitude at or above 4,000 - 5,000 feet, you should lean your mixture, in order to provide for optimum engine performance.
