Last night the Mythbusters put about a 2 inch layer of clay a a sedan and drove it at 65 mph and recorded their mileage. They put dimples in the clay, like a golf ball, and repeated the same test and got 11% better mileage. This again begs the question why don't wings have dimples, especially for...

Anybody still monitoring RAH?

Here's a link to view a successfull conversion from a Franklin powered Seabee to a Chevy LS-1 powered Seabee. The conversion has flown over 600 hours. Improvements in climb, cruise, fuel consumption and takeoff over original. Interestingly, the conversion makes more power than the Franklin...

The Impossibility of Flying Heavy Aircraft Without Training Nila Sagadevan | February 21 2006 Nila Sagadevan is an aeronautical engineer and a qualified pilot of heavy aircraft. What follows is an attempt to bury this myth once and for all, because I’ve heard this ludicrous explanation...

Yo Hitlaw, have you been spotted at the Sebring show? chuckle -- Posted via a free Usenet account from http://www.teranews.com

As I continue to research, the Zodiac XL and the Sonex are on the short list. Both offer a couple of engine options including Rotax 912 (variations) and the Jabiru 3300. Real-world performance doesn't seem like it would be that much different, at least on paper. I hope this isn't a religious...

Can you tell me what parts do I need to create a truly EVIL plane from hell???

I have no ties to any of this Dennis Fetters guy or the Mini 500 debacle. I ran across these postings about Dennis a few months back and started reading all I could on the groups and the web about Fetters and this helicopter. All I can say is unbelievable.... I have read things tossed back and...

Okay, I don't want to pay the fuel bill on a monster engine. I do want to go fast. What kit or plans homebuilt will go 200 mph on 100 hp? tom

I see mention of "PK" screws. Can someone point me to an illustration? At http://www.aircraftspruce.com/menus/ha/sheetmetalscrews.html is a Truss Head Type 'A' sheet metal screw, which is what I'm visualizing; is that it? - MIke

Having been a lurker on this site for a while, I'm not sure what I'll get as a response to this post, but here goes: I have a long term plan to get a PPL and build a plane for cross country travel (from South Dakota to Idaho, so it would involve flying over the Rockies). Maybe a Dyke Delta, but...

I have been trying to do some calculations of how much battery power would be needed to keep a hang glider flying level. With some help I arrived at about 1 or 2 kW (a few horse power) for a typical hang glider with 10:1 glide ratio and 180 pound (80 kg) pilot. As a comparison, gasoline engines...

Howdy, I am looking into a power plant for a Zenith 701. I am very interested in going the route of a diesel. Would anybody have any information on either the: Smart (Mercedes) 3 cyl. 95 hp Turbo Diesel (can be chipped up to 112 hp) found in the Smart ForFour or VW Lupo or Fox (euro) 3 cyl....

I was wondering if anyone here had any direct experience with these planes, and could give me some basic info? Can they be made 103-legal? Are plans still available? How easy to build & fly, stall speed & characteristics, etc.?
