I'm just being the friendly neighborhood pedant. ;) Your post was spot-on, but the glider pilot in me just couldn't resist.

I remember those! My God, has it been that long??? o_O

The Wright 1901 and especially the 1902 glider would like a word. ;)

I don't like the look of what appears to be raw and delaminating plywood forward of the stick. That gunk at the bottom of the most-forward bulkhead would be something I'd want to look at a LOT more closely, as well as all the nooks and crannies anywhere near primary structure all over the bottom...

Including the Triumph TR-8. My friend has one. And it... <whispers in hushed tones> runs. o_O

If that's true, then @PTAirco I may be able to help. What I have is an adapter plate my father engineered to marry a Buick V6 to a Triumph TR-7 transmission. I don't know if I can find the drawings, but I have the article itself. And I'm relatively close. E-mail or DM me if you'd like to take a...

Interesting. The first two interior images don't give me any pause. Looks relatively clean for its age. The cockpit, however... Here there be tygers. Looks like a lot of moisture has been in there, whether from people's feet or a leaky canopy. On a wooden airplane, that concerns me. Depending...

This is spot-on. Especially the last six words. :confused:

Bigger question: How many are actually using FEA as opposed to old-school methods? Most of the composite-structure discussions I see here by our local experts reflect spreadsheet versions of various composite structural calculations, not FEA. FEA is so terribly model/meshing dependent that even...

Hanlon's Razor: "Never attribute to malice that which can adequately be explained by stupidity." The extra frosting for government officials is a gigantic dash of apathy. They literally don't care if you get an outcome. I'm dealing with family law of another sort right now and the bureaucratic...

Every fighter in service starting with the F-16. It can allow for extreme maneuverability - very rapid pitch rates.

You're thinking in terms of an airplane with positive static stability. At low speed (high angle of attack), a positively-stable airplane requires nose-up trim, as you say. But a negatively-stable airplane in the same circumstances requires nose-down trim, because without any trim at all it...

Another way to put it is if this aircraft is at a positive angle of attack, its natural tendency (because of its negative static stability) is to diverge to a higher angle of attack, exactly the opposite of what we're used to with statically stable airplanes. The "trim" required to maintain a...

Shows you how good my attention is today. 🤣 Good luck!

Based on past experience of many projects being sold here, listing at least an OBO price will get you more interest.

It's possible, but not by a lot, and requires careful management of elevator span and wing taper. I've played with (statically stable) flying planks and, IIRC, was able to get the last iteration of the flying plank glider in the album linked up to roughly Cl=1.2. The trick is having the...

General simplification. The taper break on a multi-taper wing isn't necessarily at the structural break, and probably won't be. I haven't made a final decision, though. I like the multi-taper, but am almost pathologically averse to scope-creep at this point.

Most of that was still above my level of electronics understanding, where I know the magic electrons go into and out of the magic box through the metal strings somehow, but I think I have the gist of your overall philosophy. And I, for one, am a huge believer in "requirements engineering." ;)

It's like you're almost speaking English. ;) Just finding this thread. Fascinating.

That thread is here: Trailer Design - Resources?
