Judging from the calls that I am getting I guess that it is my fault for not emphasizing that the AOSS can be purchased from Aviat as a factory option.
Contact your dealer or Aviat directly for more information.
Of course, the modification can be purchased from AOSS for any previously built Huskys.
The reason we call this a "modification" is that the kit can be installed in such a way that allows the original Husky MLG may be installed if you wish or the PA-18 gear and the AOSS.
Contact me for more information if you are interested. We can supply a CD of the installation steps so that you can see in more detail what all is involved in the modification.
