" Does the FAA require a landing light for night flight??" 91.205 (c) (4) says "If the aircraft is operated for hire, one electric landing light." By definition Experimentals are not "operated for hir

Thanks Paul: The shearweb is involved with one of the cuts (the other goes barely into the top surface of the wing). I plan to repair the shearweb the same way I repair the rest of the glass. I am thi

I guess I should add, initially I was thinking the areas might not need to be repaired because they are inside the fuselage and not part of the spar-cap, but I now realize that's not the way to approa

Obviously I wasn't clear. I understand the basic repair process. However, I am dealing with two areas that attached to bulkheads. Do those bulkheads contribute to strength? Do they prevent twisting in

I am still looking for ideas on repair of the wing prior to testing, esp. the leading edge where it attached to the seatback bulkhead. I would also like to hear any ideas for how to jig the wing prior

I picked up the wing this weekend from Sam Kittle and brought it home. The wing was cut out of the fuselage with a sawzall and their is damage in two areas. (The fuselage is going to be used in a moto

Hello All; it's that time of year again. We are planning the Contact Magazine Alternative Engine Round-Up and Tandem Wing Fly-in for this year. Here is what we have so far: Dates: We currently Plan 27

Okay Pat: Yes I'm glad to hear I was wrong. This does expose a big communication problem with my local EAA group. Mike Perry Patrick Panzera wrote:

Pat: Several people are confused about the LSA rule and E-LSA. I don't know who those people are other than me. At the local EAA chapter I hear a very different message about experimentals than what y

I agree with Matt, "[E-LSA] is all very disappointing." I would like to suggest everyone bug there EAA chapters and anyone they know at national about this. The whole LSA movement does little for thos

Jay: First, I probably am splitting hairs. The 1 G load on the wing is probably between 32 and 38% of the weight; I am trying to get a more accurate number but it is a small difference. The 1 G load w

Believe it or not I grew up speaking standard American English but you wouldn't know it from my last post. What I was trying to say is: You have to know where the center of lift is on each airfoil to

Thanks to Earnie and Mike, however, I still have a few problems: 1) What is the center of lift for each airfoil? A flying Q is balanced between 2 airfoils; the CG defines the center of lift for both,

I am making progress on testing Dave Chalmer's wing, either to destruction or to a very high G load. Before I meet with the Prof and students at Cal Poly I would like to know what percent of the airpl
