Cap'n Dan, BINGO! Well, not quite. Airfoil choices are a compromise and sometimes a band-aid is needed to make a particular choice work in a particular application. The LS(1) airfoil wasn't the only c

Paul, Not underneath. On top. It is UNdesirable to have undercambered elevators on canards. It IS desireable to have a slight REFLEX (reverse camber near the trailing edge) on the elevators of canard

Michel, Yes. There is no undercamber on the GU elevator so the aero forces involved are not large. However, the system does rely on the up-spring to hold the trailing edge of the elevetor down in flig

Sam, I think you're thinking backwards here. The described behavior indicates sparrow strainers that are too small, not too large; or not angled enough (trailing edge up) instead of too steeply. Witho

Peter, From your description this sounds similar to but different from what I have. Could you send me a quick low-resolution black-and-white scan of these documents so that I can compare with what I h

Test

Jason, Due to dihedral, the measurement of sweep is not as straightforward as it may at first appear. The plans don't say anything about sweep, they only say to put some reference marks on the jigging

Jason, You do not have the complete plans. What you have is three pages that start with the words "Dear Builder." The complete LS(1) plans include this document, but are also composed of seven more pa

What was your plan if you had got airborne? David J. Gall

Jim, Look in the files section for the Q1 Pilot's Operating Handbook. It is a .pdf file uploaded by Dave King. David J. Gall

Agreed. Check the files section under "Side Cooling" for the late Larry Koutz' excellent work mapping the low pressure area on his Q200. David J. Gall

Jim, That's some good-looking airflow you've got in that wing/fuselage intersection! David J. Gall

Christopher, I am not interested. David J. Gall "Learn from the mistakes of others; you won't live long enough to make all of them yourself."

What was the project? David J. Gall

Russ, You already found in paragraph 4 of the LS(1) addendum where they say the canard cores from B.L. 0 to B.L. 15 are cut into two pieces instead of one. Read the sentence immediately BEFORE that se

"...[D]ifferent (stronger) front wing..."? No, not just stronger, completely different front wing. Different structure, different airfoil ( <--- RUSS! You can't just use the Q2 airfoil templates!! ),
