    Looking for Clarity

    Hi all, The following book is in the Technical References forum and has 3 smiley faces. In it, there’s a graph that I can’t find anywhere. I’ve gone through ANC-18 and -19 and can’t find it. Any ideas? Another question. He uses a table from Bruhn to determine his wings moment and...

    Model airplane spars

    Hello, I’ve been talking with a friend who is into large scale RC models. He was showing me the plans for a 1/5 scale Ta-152 and a question formed in my head. Can a full size airplane use a spar constructed like a model, I.e. using spar caps across the top and bottom of the wing ribs and then...

    Basic Sheet Metal Question

    I’m ready to prime some of the parts for my Moni and I have a quick question. I’ve tried searching through the forums but haven’t found what I’m looking for. Probably “operator error” when it comes to search keywords. I know how and why to finish the edges of aluminum to avoid stress risers...

    Just Wondering………

    Hello to everyone, My son and I were talking while on vacation about building airplanes. For background, he favors sheet metal since that is where his training lies. I’ve been a wood worker all my life. We went back and forth and I thought I’d see what you builders/designers think. Let’s...

    Need Identification Help

    Hello all, Here’s a drawing of an aircraft that I saw while hiking last week. It appeared to be about 4-6000’ above me and was moving pretty quickly . It wasn’t silent but made very little noise. The vertical surface appeared to extend above and below the wing. There was no fuselage behind...

    War Aircraft Replica (WAR) “Project”

    I am selling the spruce and most of the plywood to build a WAR bird. The spruce is cut to dimensions specified by WAR as well as referencing the plans. The plywood is in 4 ft X 4 ft sheets. All the wood was purchased from Aircraft Spruce and is still in the shipping boxes. If interested, I...

    McCulloch Model 4318A / MilSpec O-100-1

    I have a 72hp Mac motor still in the shipping box from the gentleman I bought it from in 2012. The motor has been in dry storage in New Mexico and Minnesota ever since. The previous owner changed the plug boots for conventional use and installed plug adapters to change from 16mm plugs to 14mm...

    Adjustable Horizontal Stabilizer

    Hi all, Does anyone know of a small wooden airplane that used an adjustable horizontal stabilizer instead of an elevator trim tab? I’ve tried searching this forum but nothing comes up. I could be using the wrong search terms. Any examples, drawings or links would be great! I’m most...

    Mixing wood species in a fuselage build

    Hi all, I’m getting ready to start a WAR Fw-190 and was wondering if there is anything wrong with using Douglas Fir for the longerons and Sitka spruce for the rest of the structure. The plans call for Doug Fir or spruce, so I’m assuming there’s nothing wrong with this idea. I couldn’t find...

    Looking for reading material

    Hello, I’ve been looking for ANC-4 and 5 on the internet and in this forum and haven’t found them. :ermm: Does anyone have a source or a link for them? I’m mostly interested in ANC-4. I’m trying to design/size a wooden spar. If there’s a better resource to use, please give me a hint...

    Weight Estimation

    Hello, Can anyone point me to a thread or book that has a method for estimating the structure weight based on the material? I have some notes from a design book ( and of course I can’t find it) that said a steel tube fuselage weighs .5lbs per inch, a metal fuselage weighs .7lbs per inch and...

    Wood or steel tube?

    Hello all. I’m looking at building a WAR replica but I want to put a 165-180hp motor on it. I live outside Albuquerque with a field elevation of 4800’MSL. My question is: is the wood frame fuselage adequate for that power or should I look at making the frame out of 4130 tube? I’m...

    Need help from Raymer’s book

    Hello to all, I’ve been enjoying following this forum for a long time. I have a dilemma now; I can’t find my copy of Raymer’s Simplified Design book and I need something from it. He included a scale pilot drawing that could be used to check cockpit dimensions. Can someone send that to me or...
