    LS3 Powered Murphy Moose on Floats

    I may be one of only a few folks who have have flown the same airframe with both the M-14 and the LS (Radial Rocket/P-85). The M-14 turning a 98” diameter MT CS prop was quite the thrust monster. Yes it was a bit “oily” but simple pre and post flight procedures mitigated the mess significantly...

    Direct drive options Chevy

    If doing a Wittman style drive, an aluminum bellhousing alone weighs 14-15 lbs. What will the rest of the parts weigh?

    Lycoming combustion air actual IAT?

    Lycoming combustion air actual IAT?

My engine is a stock IO-360-A1A. Not sure if fuel injection into the cylinder head cools the air significantly...

    Unlimited Air Racing Dead?

    This is likely OT: Once again, I did not make it to Reno this year, but on the plus side I could watch the races on line and then go to the airport, fly my plane and hunt for more micro knots. I am hearing that insurance rates for pylon racing are getting to be quite expensive, even for the...

    Slotted flaps, am I on the right track?

    just this week I saw a GI TD with slotted flaps. Beautiful workmanship. My thoughts immediately went to h-tail volume and elevator effectiveness. Could be fine but I am curious. At this point, for me, I am happy with the pattern behavior of my I TD with the standard h-tail.
