Alan, the harness is Aerolight, not Aerochute. I flew the FB Simo I originally converted to this system again recently and had forgotten just how much more useable it makes the whole set up. FB modified engines are lovely to fly with so converting one of the many FB J bar machines to a better spec by use of the Aerolight harness means you can get a fab machine for not much money. This is particularly true for the heavy guys who are after cheap reliable power in the form of the Simo.
