So far 5 stars. The hub is not cheap but it is well made and is going well out front of my LongEZ. The only thing missing is a slick or straight groove tire to go with it. The tire that was Aircraftspruce recommended is really a taildragger tire with a saw tooth tread pattern that could pick up a pebble and flick it into my pusher prop. Can anyone assist me find a 4 ply tough straight groove or smooth slick tire that will fit on the 4 Grove and get up into my Longez wheel bay?????
