This is a Zenoah Z445 twin. It is close to new as it has never been flown. It was bench run and mounted in a Meister Corsair. It was removed from the unfinished plane and placed back in the box. It comes with original box and paperwork and the two canister mufflers. $485.00 plus shipping I also have a NIP set of BCM mufflers for sale in another listing.
