I wonder if an Aerovee turbo is a reasonable substitute for a O-200A. They supposedly have the same horsepower rating, though vendor of the Aerovee Turbo claims that it does not lose power as fast...

Hi,

Do any homebuilders use a NACA cowling on their homebuilt?

Obviously, this applies to planes with radial engines, which greatly narrows the field of possibilities among homebuilts.

I have been thinking about building for a long time. I even bought a set of Jodel D-18 plans. Douglas fir is the specified wood for this design.

With regard to getting good wood with appropriate...

I have seen a copy of Jodel D-11plans/drawings. They were dated 1 June 1951.


Here's how I interpret that based on the explanatory document at the copyright office that I referenced earlier. A...

This is both a general question and a specific question, or should I say questions?

There are a lot of downloadable plans out there. I'm talking about old designs, not new ones. How would I figure...

The document "PROPERTIES OF LUMBER PRODUCTS" by Hernandez and Green, found at...

I have a couple of scraps of LVL that were left over from a construction site. I just did some measurements on it, and the veneers averaged 0.125" thick and the density was 32.4 lb/ft^3. I don't know...

Thanks for the comment and data sheet. The data sheet is pretty typical of the ones I have found on the web.

The problem with using these data sheets to compare LVL specifications to (for example)...

Adding one more thought to my last post, what is the relationship between allowable bending stress and modulus of rupture? I assume that allowable bending stress is probably the modulus of rupture...

Thanks for the comments. I have not been successful in finding all of the LVL parameters from manufacturers online sources. For example, I have not yet found an online manufacturers information...

I am wondering about laminated veneer lumber (LVL) for structural members.

Depending on the grade of LVL chosen, the modulus of elasticity for LVL products can be as high as 2E6, which exceeds the...

Thanks Dave.

Hi.

New here. Dreamer, not builder so far.

What do you all think of building a Jodel D11 with converted Corvair engine (nominally 100hp)? Are there any particular things to watch out for with...
