RE: ENGINE FOR SCREAMIN DEMON???
I did get to run a couple of tanks through it.I unfortunately didn't bring ear plugs and it was brutal but great to hear it run.The only props I had were two 7.4x8.1C which I cut an inch off the one and rebalanced.I was getting 24,000 out of it and going by the Quickie JETT QM40 page on the Jett site I should shoot for a prop that will turn 26,000 running rich.I'll try cutting a little more off the prop and a friend is going to bring some carbon props he has which may have a little less pitch.I did do one sloppy move and that was running it on the tank that was on the stand instead of the Jett tank I bought.I'm going to set up the Jett tank on it for Sunday so I know fuel delivery is not an issue and I'll get a video for you Mike.
