Precise evaluations of aerodynamic forces on highly spinning golf ball are very difficult because of less method and technique to measure these basic characteristics. We are challenging this problems using newly introducing air suspension balance method. Atmospheric and supplying air pressure change on air force of Z-direction measurement are studied by introducing cancelling technique by using a dummy balance. In this stage, cancelling result of atmospheric and supplying air pressure change is shown. Drag forces on ψ0.3mm piano wire is measured and is well agreement with well known data. The drag force measurement on spinning golf ball is reported as a result of trial experiments.
