    Two V8s, a gearbox and a pilot all held up by a couple of tiny, thin wings. Sounds like flirting with death. Bet it sounds awesome.

    Nice find. I've never seen anything on this one before. I found a little more information online but nothing seems recent. Most of it is from 2007. http://www.reddit.com/r/aviation/comments/14lmsl/does_anyone_know_what_the_latest_is_on_david_rose/
    This post claims the the engines are 598 cubic inch 2700-hp Dart V8 drag racing engines and that the propellers are not geared down and that the exhaust stacks alone create 300 pounds of thrust.

    [​IMG]
    This was a quote I found. "The RP-4 is being built to either kill Dave Rose or catapult him into aviation glory for the fastest piston-power aircraft (something around 529mph)"

    I think it needs a spinner.

    I'm sure they considered that drag racing engines have a lifespan of seconds at full power, 'cause that thing looks like a really bad glider.

    I'm guessing the cooling system is in the wings?

    Looks like the canopy could double as a parachute. 529 MPH with fixed gear? YeeHaw

    Gear is retractable.

    Has anyone seen evidence of this thing flying?

    That looks to be about as viable of a flying machine as the Bat-mobile would be as a daily driver.

    That horizontal stab looks like it's more than capable to the task. :D Not to mention it's gonna require about 529 MPH just to get enough lift on the wing to get airborne.

    That's the first thing I saw... the dinky horizontal stab.

    Doesn't look like it will have much ground clearance for the needed big-azz props.

    The description said the props were run direct-drive, not through a gearbox. Given the RPM at which racing engines make their peak power, prop diameter would be very limited.

    Also, 2500 HP out of 529 cubic inches is about half the HP/displacement the elite NHRA Top Fuel guys are making, so TBR is likely much longer than a few seconds. The plane could probably make quite a few record attempts before the engines were spent.

    Looks very useful.... as long as you're trying to make the world's largest Daiquiri.

    are those propellers or fan blades for the radiator?

    It won Sport Class at Reno last year.

    But they're not "big azz." Given the props are turning at the engine speed which given these things are ungeared dragster we're probably talking over 8000 RPM, they're the little cuisinart blades shown in the first picture.

    What's amazing to me is how far back you have to place the pilot to balance out the weight of those engines.

    As for dinky horizontal stab, downforce is drag there. You decide to suffer some stability if all you care about is flat out speed. Just add more after CG.

    Well, it doesn't look like you'd be bringing much cargo along :)

    Is this real? Where are the radiators for those liquid cooled engines that produce so much heat (HP)?

    It is all in the links. There is a system to route the hot coolant through the crankcase to heat up the oil on cold start, pilot controlled to direct the coolant to the wings when flying and also a radiator back in the tail for taxi ops.

    I can not find any reference to answer if it has flown yet. -Skip

    little harsh on the wording there. the airplane did not kill the pilot. read the report, it was a simple stall trying to turn towards a runway at low altitude with an engine out. dave was a top qualifier in that airplane for years.
