1 New High Quality Aftermarket Handheld Control for the Curtis Straight Blades # 1HHC. This is the newest control Curtis has. It will plug into the harness of the older touchpad and the joystick. There are two versions of this control. One has 7 pins and one has 9 pins. However, these controls are both 1HHC and both 9-pin types and 7-pin types will work the same. Some will also say "Sno-Pro" in the center while others have simply "Curtis". The full Curtis part # is CTS1HHC. It comes with a small mounting hanger bracket.
