Through two years, I am back. I have tried to connect with this Usenet from 2004. But I have not succeed. In 2004 year, I wrote a question" how long a GYRO can be used?". At that time, being a manufacturer, we did not know how long times about our GYRO. I am so glad that I can see this Usenet...

rec.aviation.homebuilt U shaped wings Some time ago there was a magazine cover showing a twin engine aircraft with a U shape in each wing. The U's curved downward then up again with engines and props within the U. When did that occur and what magazine was that; anyone know? A vague memory...

Here's a model report on treating home-builders like grownups. Highlights: Mass balancing controls - tight control wires not enough Reduced stick force per G at higher G made worse by aft CofG Don't push the stick hard by mistake - it may be your...

be tuned to make 100 HP?

Hi! Any RV builders out there? I just joined this forum and am building an RV-9A.

Planning to build or buy a Volkswagen engine? Right now all of the major components come from other countries. Brazil produces crankcases. Mexico casts the cylinder heads an produces most of the auxiliary components such as the cam and its gea or the distributors pinion gear. China has taken a...

I have to replace the trailing edge end of a stamped aluminum rib from a '47 Tcraft. I've cut away the corroded portion, bent metal to replace that part and would like to use Cherry "N" rivets to hold it in place. I have some questions regarding what spec to look for when ordering. A. Rivet...

The specs for my C-85 are upper plugs mag @ 28* BTDC and lower @ 30*BTDC. My results are upper @ 30* BTDC and lower @ 32* BTDC. I couldn't find a "flower pot" with attached degree wheel to borrow and attach to the prop hub so used a little "mickey mouse" circular protractor with a free swinging...

Anyone have experience with these? Wag Aero are selling plans for these still. Anyone know of their history? were they always a homebuilt design? Are they compartmentalised like Edos? Performance? ease of building, expense? TIA! F1

Quick question for the group. When setting the torque on prop bolts (I have bolts with nuts), if the hole for the cotter pin doesn't line up with the castleated nut at the proper torque setting, is it better to go tighter or looser to get the hole lined up. My gut instinct says tighter,...

Three new additions to our Rec.Aviation "Rogue's Gallery" of participants and their planes... - From Pennsylvania, Mike Granby and his beautiful Piper Arch-Warrior (180 horse Warrior)... - From New Jersey, Lee ("RossPilot") Ross' gorgeous Skyhawk... - From Colorado, Chris ("SeeAndAvoid") Rodiguez'...

I want to get airborne with as little building involvement as possible. The cheapest way. And with little maintenance as possible. What are the possibilities? I mean building a gerobee could take years and lots of money and this rotax motors are 'spensive. Building a wooden woodhopper could be...

Builders who plan to fly in mountains needing higher altitude should consider their engine choices. Typical Lycoming low compression engines have a limit of about 13,500 feet. You need higher compression engines or turbocharging for higher altitudes. I tested my high compression (10.5) Franklin...

Pretty incredible story: http://www.ez.org/birdstrike.htm Long-EZ pilot at 9,500 feet hit a bird, which shattered his prop, and the broken prop took off almost all of one winglet. Full aileron was only able to keep the wings level above 110 knots. Landed safely...sounds like a damn fine...

For $1750, you can have a decent experimental A-65-8F, which type of engine has flown more than one aircraft for over 1000 hours. AND has gobs of premade accessories AND actually puts out 65 horsepower AND doesn't require "fudging" to make weight, like nearly all auto engine conversions,...

Search on ebay for item number : 4533523478 Anyone know the name of the "famous designer" refered to? The performance claims seem unrealistic at best. I doubt even the short wing version will reach 237 mph.....unless in a full power straight down dive. Just my opinion.

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...

Did it today! After 12 years of watching the sky and dreaming, I finally had my first fly since buying the farm. (Wonder if anyone can guess why I stopped flying?) 2 hours 20 minutes of shear joy in two lessons, flew over my farm for the first time and flew a taildragger to boot! I know some of...

How can an RV-9 possibly cruise 50 mph faster than a 152 w/same engine yet stall at the same speed and give up nothing in terms of stability, etc.? P.S. Zoom is a wiener.

Hello All... Wondering how many SQ2000 builders are out there right now? I have found two of you on the web (Joel and Paul), but, wondered if there were any others out there. Any more websites showing a build in progress. I am considering building this plane out of a list of (SQ2000,...
