Hey all,well I flew my H9 USL120 with this engine today,and all I can say is wow!!!!I feel like I've got a totaly different airplane,it has a take off roll of about ten feet.Vertical perfomance is limited only by my eyesight.Jody you were right on about the 20x8 prop this engine really seems to like this prop.I started out with a 18x8 prop and it flew just like it had the BCMA 26 on it,I then tried 20x6-10 wood prop on it and what a difference it was like a rocket,but I broke that prop on the second flight.I tried the only prop I had left,a big ole MAS 20x8 Classic,I think this is the best prop for this airplane engine combo.
