Sundowner 50 goes 499mph!!!!!
Yup, it's true, I built a Hangar 9 sundowner 50, put in a 42 year old rusty engine I found, not sure what it is but it looks like about a 50 size. Powered it with KFC cooking oil after watching mythbusters. Put an APC 10x4 prop on it, got a reading of 97,000rpm on the tachometer, but I think it was rich because the chicken didn't quite smell cooked.
Then I took it out to the local school yard where they had an AMC pacer there to drag race me to verify speed.
After the 2nd pass it looked like the sundowner was about 10 times faster than the pacer so we timed it by counting 1 mississippi 2 mississippi etc to verify. We didn't have dopler but my dog whined when she heard the engine.
Yup, it's an amazing airplane and that used chicken grease lubricates really well, best part is, my dog cleaned my airplane for me when I was done!

RE: Sundowner 50 goes 499mph!!!!!
The pacer was mostly rust colored, but some baby blue under the rust. It was a high performance pacer though with many speed holes placed along the lower rockers, wheel wells, doors, hood, roof etc. It also had much of the drag removed, such as bumpers, lights, etc.
The driver was some dude I found under the bridge, he was willing to risk it all to top out the pacer for only a cup of coffee and a bagel.
I just received word from the local entomologists society that they received some satelite images of my sundowner on an old russian spy satelite they had purchased a few years ago and with careful study, they believe the sundowner actually exceeded 500mph. They said they drew this conclusion by comparing the flight pattern and distance travelled over a set amount of time to the cullumanus species of bumble bee during their mating season.
This evening I have been trying to figure out if there is a correllation to speed and the pitch of my dog's whining. There seem's to be, after playing countless hours of F1 racing video tapes, and recording her whines with known different speeds of the cars and their engines, then dividing by the number of cylinders in the engine, divided by the displacement, times the displacement of the engine used in the sundowner, taking into account power loss with the propellor, but also increasing the thrust due to the density of the air I think I have come to a very strong conclusion.
My dog told me tapping her foot that she needed to go outside.
I think with all that information, the rotation of the earth, the gravitational pull, and the wind speed, plus all of our incredibly accurate and calibrated speed measuring equipment, that the sundowner did indeed go at LEAST 499mph, probably closer to 600mph though.
chicken grease, it's not just what's for dinner!

i will eventually get into extreme speed prop planes, too many projects going on right now though. it is amusing though watching the back and forth here on whether a plane goes 175 mph or not. i would think that having a plane that flat out hauls $ss would be enough satisfaction. unless you get into true high speed like the above plane did. then you just have to know, all of the testing and speed recording is necessary to know exactly what kind of speeds you are reaching.[X(] [X(][X(][X(][X(][X(][X(]

RE: Sundowner 50 goes 499mph!!!!!
Ok guys, the only part I just can't believe is that a rusted out Pacer did 49 MPH average for 2 laps! Figuring a cornering speed of 20~23MPH the straight away speed must have been nearly 60 MPH!
I really think the pacer pilot should get the Kudos!!

And it is enough satisfaction for me. It is amusing until you find yourself on the butt end of it. I started some threads on some fun I been having with a plane thrown together with a powerful engine and for most part most of the members here get it, this is about fun, whether the plane did 150, 175 or 194. It hauled boogie and thrown together! But then there are the few others . I am not sure if this thread was started because of the Meerkat thread or not, I just hope guys have fun with it.

Z don't get your feelings hurt. This isn't about you. It is about all the crazy speed claims that come up every few months. After a few years of reading about the accuracy of measurments, prop formula, pathagorian theorem, etc it all boils down to fun. I think of it as the begeezus factor. If I need a new one after a flight I was doing pretty good.

Finally a guy who gets all this top recorded speed nonsense! Well done sir! I travel around at 1.4 jigawatts if anyone named Marty cares.

On November 5, 1955, Emmett Brown came up with the idea of the flux capacitor after slipping and bumping his head while standing on his toilet to hang a clock. The idea came to him in a vision he had after being knocked out.
In order to travel through time, the vehicle integrated with the flux capacitor needed to be travelling at 88 mph (140.8 km/h), and required 1.21 gigawatts of power (1,210,000,000 watts), originally supplied by a plutonium-powered nuclear reactor.

RE: Sundowner 50 goes 499mph!!!!!
I didn't want to spill the beans yet BUT this is a good time to promote my new kit:
- 3 speed > Fast, Faster, Soil your underwear fast (MIT estimate is close to the speed of sound)
- The kit includes engine & Real-Fast 2.4 JigaHz Tx Rx combo so you don't miss the left turn
- Street price not determined as of yet (have to add up all the property damage lawsuits pending from early test flights)

Well , my new old plane uses people who fib about their airspeed as propulsion! They don't burn very efficiently but they never ever lie about their speed again either!
