Could be wrong. c.) How much force is required to deflect it back to that point? d.) Where will the surface deflect to under maximum flying speeds/pressure. e.) How much is due the modulus of elasticity in the materials in the aileron itself.. i.e. is it in the bell-crank linkage, hinge, or after that, back somewhere in the wing, where/why? f.) How does that compare to the velocity/other similar builds with similar control linkages and material construction. g.) What does he know the make the assertion, "I am ok with that." that I don't. Or is he wrong? Don't know the answers. etc. Very curious to hear thoughtful thoughts.

You then concede the aileron movement (bouncing in fact) observed in the taxying videos is not due to Peters (or is it Mike’s) hand on the stick and a rough runway?
So why is there so much slop? The ailerons are cable actuated and I’d guess he needs more cable tension but can’t add tension because the cable pulleys are skin mounted and tightening the cable across the pulley results in skin deformation or threatens the integrity of the pulley mounting. On the other hand the control system design may be poorly engineered, even completely flawed like the Fowler flap used for pitch control initially.
I’ve never been to Brazil, don’t have any billionaire friends, never operated a nuclear reactor either but I have worked on and flown quite a few different aircraft. Haven’t seen one yet where that much play in a control surface was acceptable.

Will need something with longer legs/ETOPS cert that time of the year. But we can make it happen. Bit more in the wops you know? Kia Ora buddy.

I’m all in. But I can’t imagine why you’re so obtuse about it.

No, absolutely not. It is a possibility (and maybe even probable but seems "a bit" too egregious to slip by... maybe I am wrong. Don't think so. See b.) above) I don't think he is that stupid. (something many folks seem overly zealous to jump to imho) Could be proven wrong. Doubt it. Would like to see side by side cockpit vid/wing mounted vid.
Your second paragraph is as much conjecture as my questions above. I just did not jump to the same conclusion you did. Maybe I should have but don't think so. If your guess is right then all bets are off. Just don't think that is the case. Thus my other questions. I don't have any 3 comma friends either. And am bad with names. Dyslexic aslos.

Hmmm, as long as we don't get one of the motorcycle muggings and we drink on the beach. I'd still be afraid we would be getting catfished.  But, we would be on a beach in Brazil.....

Exactly the kind of guy I want monitoring the gas if I was going under for surgery. Just maybe not the kind of brain built for accurately calculating long odds better than others. Can't have it both ways man. Not my rules.

I'm in for $100 towards airfare for Stuart.

And you respond with insults. Classy.
