Yes the screws are the sheet metal type with the allen head I used four since that was the way Gary sent the hub. The blade mount with the round plate I also flew He sent two different kinds and they both worked very well. The hub has a cone shape on top so you can spin up with a drill which I use most of the time I have 15 flights on Garys hubs now and I pretty much stay up until the tank is about empty. The flights are 10 minutes or more I would guess.I am thinking about Muncie could happen
