When trying to set the RPM in the VSPAERO GUI for bladed, symmetric Props, the RPM values and available Prop numbers alternate and reset to the default RPM (2000). There is a weird alternating Update reset to the propeller RPM parm when you try to select the Surf 1 Prop but it also does it when you orbit the model but not pan. It's really specific to this one parm though. For example, symmetric Props modeled in Disk mode, with Actuator Disk selected does not exhibit the same behavior.
