Wing Tip Shape Summary

[rotto789]

In my short experience:
Droop tips suck. I found no lift advantage and the
make it difficult to see past the wing from the cockpit

These are the reasons I dont want to install the droop tips on my smith cub, mine came with the kit, has any one had experiance with no tips at all ? just fabric rap the end rib and maybe put a stall fence on the trailing top half of the tip rib, I have seen some represntations of this on a few other cubs, one of wayne Macky's early SQ2s had this, is there any advantage or disadvantage of doing it this way? would save a guy some money if he didnt have to buy wing tips, fabricating a fence would be a piece of cake.

Rick,

I plan to do exactly that. But i will fabricate and end plate with the fence incorporated. When the supplier of my wing tips told me that they are aesthetic only, I wondered why I bothered putting them on. The small fence needs some research. Are there any pictures of wayne's?

[Ruidoso Ron]

Yeah, I guess that's the trick word..usually
Of course I've bumped into a few things and
nothing on the plane bounced back...cept me.

Yeah Joe, I think I have pictures somewhere. If you would like, I'll try to dig them up. Who loves you Joe?

[Steve Pierce]

Joe, I have a picture of Ron if you need a little "dig" on Ron.

Hell Steve! The whole world has embarrassing pictures of me in a Super Cub. I'm kind of like the Paris Hilton of SC.Org. (Maybe I should rephrase that) I thank you in that, at least, you didn't have t-shirts and coffee mugs made from them.

O.K. That's more posts in the last two days, than I've posted in the last two years. I think I'll go back into hibernation. Wake me for the OK18 Fly In.

LOL, I am just enjoying you guys return. You haven't seen pictures of my adventures this summer.

No, but I have heard stories.

Rick, Super11xp on here has no wing tips, maybe he would chime in?

Goldy,
Here is the link to Wayne's early SQ2 review has some good pictures of his wing tips, or lack of !! I think a guy could fab the fence out of 1/8 lexon or plexy, would be paintable and easily repaceable if you were to say hit a branch or something Ha Ha !!

Goldy and Rick, The tip plate/fence is simple, but the advantage ends there. Wayne changed to a Sullivan/Hendricks style tip after testing revealed that the tip vortex with that tip fence/plate was hitting the top of the wing about 4 feet inboard of the tip....not a good thing.

There is some discussion here. If you look hard enough, or someone does a search, there is discussion where Jerry Burr talked about his research and gave report to flying qualities of various tip designs. I believe the Sullivan tip ends up with highest marks...still, it's just a wingtip

Dave,

Do you think the Fence would be better served on the bottom of the trailing edge in a similar fashion to the one that Wayne had on his old SQ2 only inverted? that way the vortex would help create lift,( I am just thinking out loud here, I may me be way off in my thinking), would still resemble the Droop tips only smaller, less surface area and create less visual intrusion under the wing......Just a thought.

Steve, Ron y'all stop foolin around on this site.
These guys are serious about this whole wing tip thingee...
Check this out: "would still resemble the Droop tips only smaller,

Visual Intrusion! Steve, chew on that for awhile.

[Cajun Joe]

I'm sorry rotto789; truly I am.
I am a dear romantic when it comes to the English language
and the cleverlessness of warping words..
I thought your phrase "Visual Intrusion" was really neat
and pointed it out to SP because he is a serious student
of Cubisms.
As far as how it relates to wings, I have no idea.
As far as stupid comments go, speaking for Massey
"he makes a lot of them."

[Cajun Joe]

Southerner?

Guess I'll join Massey and "hibernate" until OK18 rolls.
Later

Dang! After carefully 'splainin' to Joe some years ago the similar linguistic usage between "coonass" and "yooper" (i.e., either a term of endearment or fightin' words, depending on who sez it and in what tone, one meets t'other . And of course I enjoy both cultures. And this has been an interesting string.

Rotto, you'll hafta do some research (lighter than air area, I believe), on a piece entitled approximately "Joe Moves ta' da' U.P." [Which Joe took with good grace and some fun banter.]

Tanks, eh? cubscout

I usually just tune you guys out. Between you and the nimpo/tango deal, I can't keep up with you......and wouldn't try if I could.

Goldy, I don't know the answer to your question. Wouldn't hurt to experiment. Did you try using the search function for that Jerry Burr stuff about tips. Maybe he discussed it. I do recall a discussion of "splates", which I think is a tip plate.

DC, are you sayin' that you are somehow miffed @ the good-natured bantering between some of us?
I kinda figgered it would elicit a smile, not "tuned out" irritation.
SORRY if that's the case.

[cubdriver2]

I told you guy's this was right on the money I posted this last week, find your caracter


This is an example of how we all get along somedays

Hah, I am rarely "miffed" Logan.

I read what everyone writes.......some of it gets tuned out. Most of what George writes gets "tuned out"...and Eaton

I just don't have the mental capacity to comment on it all

[Dave Calkins]

Glenn, if that's the birds on the wire, I got a kick out of that. True, true!

Does anyone have the installation instructions for the Ferguson tips? "Upper Valley Aviation exhibit no. 2a report 101-250 dated august 30, 1965.

Thanks in advance!

[flybynite]

Ferguson tips installation for pa-12 and others. The only number that corresponds is 8/30/65
Not sure if it will help at all but...
