Low RPM on take-off was created by John Farrell
New Ercoupe owner here. Just finished my second hour in the plane with instructor: Four take-offs same number landings! On each take-off full power standard temp sea level, Gross Wt or slightly above, RPM on climb never got above 2100-2150 climbing at 80mph. Cruise RPM came up to 2300 -2350 with full power indicating 115-120 mph. Engine C-85 with McCalley prop IA90 CF71-48. My concern: shouldn't I be getting more RPM on climb out? Thanks in advance for your help.
