Does anyone here have any actual experience with reduction drives/kits made by Gyrodynamic Systems, formerly of Redlands, CA? They used to advertise all the time in Sport Aviation. I have a copy of their plans but have never seen one made up. It's a simple planetary redrive using parts from a Corvair automatic transmission. I would be interested in any info, experience, basket of parts, etc.
