About a dozen years ago I had several phone conversations with Lleon Davis. He sent me some literature and an 8 x 10 of the (DA -8?) TX-1. The plane has been built but Lleon offers no plans for the plane. Has anyone heard of someone who has bought this plane and will be offering plans for it? ...

Bob and other Group members, I’ve purchased plans to the VP-1 and downloaded study plans for the VP-2, all research and background indicates the VP-1 is the best build of the two. Some have lengthened the wingspan or created a bit more fuselage space for storage and it appears the 1835cc is engine...

I could use some brainstorming on how to approach the rusted cluster shown at http://members.cox.net/mhorowit/cluster/ - Thanks, Mike

Much ado has been made of the Mars Rovers and the use of a vehicle to explore the moon in the 1970s. I was curious if there was enough atmosphere on a planet like Mars that Astronauts could utilize Ultralights in their exploration and if so, what would the make-up of the ultralight aircraft be,...

Somewhere I read about a welding exercise where the student built a tube frame of some sort, pressurized it, checked for leaks, then smashed it flat and rechecked for leaks. I've looked thru my books but can't find it. Anyone recall where I can find a description of the exercise? - Mike

The wife and I just back from our Oregon vacation that you helped us plan. You guys did a wonderful job. Day 1: Left OKC on a Canadair regional jet to Phoenix. Boarded a 737 whose APU wouldn't start. 107 degrees on the tarmac and no AC. And we left our Cherokee at home why? Oh well. Landed...

Help an old mind come to the correct conclusion G. The situation is (2) steel straps side by side and fully in contact with a bolt hole at each end . One is 4130 with about 80,000 psi tensile and the other a heat treated 4130 to a 124,000 psi tensile strength. Is the combination strength 80,000...

I have some scratches in my Plexiglas. What is the best product to use in order to remove them? They are not very deep, but they are irritating. Thanks, BJ

Hi, Has anyone had experience with removing the wings on a Cherokee 140? Need to move it to rebuild. How hard is it to re-install them. I heard something about tapered pins or bolts.. Pete

Hello everyone, Just stepped in from the shop for a few moments. I need a recomendation and/or input (based on actual experience please) regarding a BurnzOMatic Oxy/MAPP gas torch. That's the one on the Home Depot shelf that uses two small cylinders and sells for about $50. Has anyone ever used...

I'm planning on building a Boeing 747 simulator (a physical one which you can get inside!). I've found these plans for the overhead panel: http://www.glideslope.de/images/LH744_overhead.gif but I can't find anything similar for the other panels. Help!

A member of my chapter has asked me as tech councilor what would be needed to assure that the installation of a Garmin 430 in his RV-8 would be legal in the eyes of the FAA for flying approaches. This falls a bit out of my area of expertise. Can you help or direct me to help. Ed Sullivan

I've been wondering which shape is lower drag, a rounded one or a sharp one. I can understand why the leading edge of a wing would be rounded, this allows a larger range of AOA before flow speration and stall, but what about the vertical stabilizer? Wouldn't this be better with a sharp leading...

I just found out about a method being used by some experimenters to cover their wings that is intriguing. They are literally covering the wings twice with fabric. The technique involves covering the wing initially with a heavy grade fabric, taughten it with the iron as specified, apply the rib...

I have a slideshow screen saver where you can easily add your own pictures. Every time I find a picture on the internet that strikes my fancy, I save it so that it will show up as part of the slide show. One of my favorite topics is light aircraft, since I do have a PP-ASEL. There is one...

A forward air scoop gets high pressure - air ram. Does a rear facing scoop generate low pressure (suction)?

Hi all... was sketching out a plane this weekend (just for kicks, nutin serious, just playing with numbers for the fun of it)... And no matter how I sliced it, I kept coming up with needing 35 to 40 hp and a 4 cycle at that....well, the only thing I know of that fits that bill without a lot of...
