In checking the WingRigger sales records from before I bought the company, I see that one WingRigger was built for a Ka6e owner in Canada. There are some notes on the construction (like a larger wing keeper pad, special saddle and padding), but few actual details. If you are interested, contact me at: info at mmfabrication dot com. Price is likely to be in the range of a large rigger for a two place glider due to the size of the wing.
