I then added the vortex generators which made the elevator trim still more effective but not quite enough to maintain a 60 MPH approach speed with out some stick back pressure. If I let the stick float with full up trim, throttle at idle it will maintain about 73MPH. Going full throttle with full up trim can make for heavy forward stick pressure. I have a manual activation of my trim so it is as fast as I can move the leaver. The advice of a quick acting trim came from an Alaska bush pilot who said one wants to have a trim that gets off quick as possible on a go around. All said and done I wouldn't want to be without an elevator trim, it makes flying so much more relaxing.

I assumed you were making a reference to the spars, and not the struts. As far as the struts go, I will be making my own, and covering them with an airfoil in aluminum. During a trip to PA last Fall, I dropped in to see Dillsburg Aero Parts, and purchased full lengths of chrome molly tubing in every size from 1/4" to 2", so I should not have any problem in fabbing up my own struts, along with the jury struts. Robert Pelland ________________________________ Message 11 ____________________________________ Time: 02:37:16 PM PST US From: "Robert Pelland" Subject: Re: Zenith701801-List: Long wing Hi Doug, I don't think your question is sarcastic or snotty in the least. It's a legitimate question, and deserves a response. Over the years ( many years ) I have accumulated a few hundred hours in my log book, flying mostly with the Cessna's and Pipers from the local flying school. When I decided to build my own plane, STOL performance was not one of my priorities, but I chose the 701 so I could fly flying as slow as I could. I am not planning on installing any slats, and will have a full compliment of VG's on the main wings, and underneath the rear stabilizer. Since most of my flying will either be done from long paved runways, or water, I can live with the lost of a little STOL capability, in exchange for some slower flying speed. The extended wing will further reduce the wing loading, and the absence of slats will improve the fuel millage. In case no one noticed, I turned 65 a few weeks ago, so all I want to do now, is safely fly as slow as I can , and skim the tree tops. Hope this gives you a little insight on the reason I decided to go this way. Fly safe Doug.

If you had,and extended the wings inboard of the standard attach points you'd have a bit of a dihedral problem. Not my project, but I'd give serious thought to building as CH drew it.....adding inboard changes the angle of the struts, and might be a reason to re-calculate the wing loading....and that may not be the proper terminology.

Zed ________________________________ Message 13 ____________________________________ Time: 03:21:33 PM PST US From: "Robert Pelland" Subject: Re: Zenith701801-List: More Extended Wings Zed, The reason I decided to extend it inboard, rather then at the wing tip, is just for the safety factor. Once the modification is completed, I will have the exact same wing surface area as the regular wing, outboard of the struts. As for the dihedral, once the wings are installed, it will be adjusted to the exact same angle, as a regular wing. I also reinforced a few of the major parts that make up the wing, so my guess is that the extended wing, will most certainly be stronger then the basic 701 wing. Here are just a few of the changes. Spar web is cut in .032 rather then the .025 Spar caps are 3/4 x 3/4 x .125 radiused on the inside Web and root doublers, have both been made in .040 All the covering top/bottom, is being done in .020 rather then the required .016 There will be a slight weight penalty with the above, but the additional surface area, will more then compensate for the extra weight. There will however be some additional angle work to do to both the strut attachment points, but nothing that would cause any stress to the parts themselves, just a slightly different mounting angle. If you search around the web, you will see that there are dozens of 701's that have had their the wings extended, and all of them are flying with no ill effect, or anomalies what so ever. During a phone call to Calibe at the factory a few weeks ago, I informed him of my intentions to extend wing, and here was his response. He said that it would not be a problem to build in an extension to the 701 wing, or I could just build it initially to the extended length. Always happy to exchange a few ideas, and pull some rivets, which BTW is what I will be doing this evening.

One response asked if you were using the Zenith spar or are you building one from scratch. The answer lies in the method of construction. Since the sketch was for the tip end or outboard end it simply added an extender. The tip end is not structurally attached. Adding 16" Inboard or at the root can only be accomplished if you are building from scratch.

Should I read that as being " struts " rather then your use of slats, if that is the case, yes, inboard of the strut attachment on the wing Meaning will you be building a longer SPAR?

That is one reason I am not inclined to go with anything that does not add structurally to the wing.
