Doc,

Have you ever tried a 9-4 or 9-5 prop with that engine / plane combo. I've got three of those engines I picked up this winter. I will be putting the two NIB ones on a twin I am building. The used (almost new one) will be going on a scratch built flight streak wing with extended nose and tail. I will be putting a 4 oz. sullivan on it and use uniflo. I have some 9-4 props to use but found a bargain bag of APC 9-5s. BTW I like my streaks to balance just in front of the spar.

Tight lines,

Tom Perry
