3 blade Ivo with electric on the fly adjustable 18" to 52" pitch. good for ultralights and homebuilts up to 100 HP. It is a direct bolt up to Rotax. I used it on my Sevetec hovercraft. the main hub/motor is about 6 years old. the blades are almost new with maybe 10 hrs run time. there also is a spare blade. there is also a 2nd pitch change motor that I bought for spare parts, the motor runs but there are gears missing. there are 2 spinners. I think everything is there to run it on an aircraft but not sure.
this prop new is now almost $2300. a spinner sells for $70. the spare blade is 320 bucks.
If you want to run it on a Sev hovercraft I will throw some drive stuff to make it work for a little extra on freight. it was fantastic on my 16' Surveyor but I went to two engines so I could split lift and thrust functions.
