Hi Michael, Not much time to fully absorb all the items you bring up, but let me hit a couple. Airfoil dimensions were normalized for my multifoil model representation including with the Eppler main

David, The comment was strictly about the tailoring of the hinge moment. The rest was a fun history tangent. Jay, I noted a couple concerns in the provided LS(1) airfoil after running through the

Michael, Other than the general comments about tailoring the elevator hinge moment, I fail to see the relevance of the NLF(1)-0115 or the AS504X to the Quickie line of aircraft. They suffer from the

Hi Michael, Thanks for the additional comments, data and history on the evolution of the LS-1 etc. As far as what you are requesting, I am using 28% chord as the hinge point on the LS1

Jay, In typical engineer fashion, I don't get the chance to do this at my day job and got my references confused. Appreciate the patience while I double-checked everything.... The NLF development

Thanks David for your long note and discussion points. Much appreciated. I will absorb them and continue my analysis. Michael Dunning, feel free to chime in anytime. I watched that video that you

Jay, Nice analysis. I’m heartened to see that someone else has independently concluded what I’ve been saying for years: the Roncz R1145MS airfoil is a better choice than the LS-1. The Roncz

Hi Jay/David/Vern: As I said before: the sparrow strainer conundrum is pure gold. For retired aero/structural engineer types it is great fun. Ben

HAHA! Thanks, David. Browsing QDF I kept wondering if it was "that" Raptor... *snort* I avoided that "experiment" with a 20 foot pole up until watching Seguin's YT report... Since Jay is getting

Great hints, David. Thanks. Cheers, Jay

Hi Jay, I’m glad you asked; I was concerned about the aft shape of your airfoil approaching the trailing edge. It appears that the last ~15% of your shape is convex. That’s a big no-no aft of

It's not in the weeds for me, Jay We could be looking at a balancing act.

Brian, Can you make a copy or scan of those instructions for the archives? The LS(1) canard plans that I have show different dimensions. Thank you, David J. Gall

Hi David, Glad to hear you have your ears on the Q-list again. My redesigned LS1 elevator behaves nicely in the simple modeling software that I use (meaning it will remain in neutral trail at a

Just playing catch up on the last two weeks of frantic Q-LIST activity…. OMG, Michael, the “Mad Rocket Scientist” (Drew) is a nice enough guy but he’s wrong fully ninety percent of the time

Hi Jon, Don’t intend to put myself in a position where I would need to use such a beast…in my Q, anyway, I will stick with 4000’ AGL minimum radius turns, but I’m game if you want… and

When your ready Jay, let's talk about minimum radius canyon turns. 😉 Jon Finley Flying an RV-4 - Truth or Consequences, NM

Thanks for the explanation Jay. I'm pulling like 20 lbs of back pressure just prior to stall, but at the stall the force drops to zero. That made me think that the canard is stalling. Your

Looks like a beautiful morning there Charlie. Cheers, Jay

Nice Kevin, Not my Dragonfly but I got my first camping air show in the log book this year! It’s warming up nicely,Charlie My you tube
