Genesis, You wrote, "115 mph IAS" . . .
My Coupe went right at the same speed when I first bought it. But, I seemed to have headwinds both directions on every flight compared to my very careful flight plans. May I diffidently (but firmly) suggest you read through this article about airspeed indicators and calibration. The calibration/testing method way at the bottom is quite easy. http://edburkhead.com/Ercoupe/airspeed_indicator_errors.htm Sorry if it causes disappointment. If you do get 115 mph after your calibration, please let us all know how! Ed Burkhead
