A proper propeller hub has been bought and will hopefully be on it's way the first of this week .
Now for the propeller itself.
I have read these engines like either an 18 x 6 or a 16 x 8 propeller. This engine will more than likely go in an RC Guys Treehopper or a Hanger 9 Ultra Stick Lite. I am not much for doing any real trick flying (yet) just buzzing around the sky doing loops, rolls etc. if that makes any difference in the selection of one of these two.
Also what size spinner do you need for these props ???
