Does anybody on the site have experience on how successful direct drive is on the subaru EA81 engine. I watched a gyro fly with one of these engines at Benson days many years ago and it seemed to have good power also is the direct drive prop hub still manufactured ?.

I had one for years. Got about 310lbs static thrust @ 3550rpm with Tenessee wood prop 52X26". OK for pilot weight not over 180 lbs. Max climb on a good day 500fpm at 165lb pilot weight. Obviously not a great performer, but got the job done. This was EA81 single carb version.
