Pacer wings for a super cub.

[Alberta Cubber]

Hi everyone! I'm new to this forum and am in the process of restoring a 46 J3. I have an Avid STOL that I fly while this is being restored and recently i've been offered an experimental super cub with pacer wings and an 0-290 on trade for the Avid. Its not finished and the fuselage is new (experimental home built) and the wings/engine are from a pacer. He had someone build these massive Wittman tips that look like way stretched out and heavy horner style tips.

My question is whether those wings will even work on a supercub fuselage and if there's anything I should look at or for in particular that would be a deal breaker. I've read on the forums here about AOI. What should it be for the fuselage / wing attach points and how can i check it. I'd like make the best decision before I part with my flying plane for a second project.

Here's a couple pictures of the wings.

Thanks.

Ouch, Id get rid of those wing tips! Pacer and tripacer airfoil is the same airfoil as a cub. If they attach correctly (I don't know if they will) they would be like a clipped wing cub. Pacers and tripacers have a lower angel of incedence than cubs but I dont think that affects what you are talking about. I would check to see if they damaged the wings putting on those wing tips. Finally, your struts will need to change, those wings won't take stock cub struts.

The Pacer wings will attach to the Cub fuselage, but the strut attach fitting on the fuselage will have to be at an angle of 30 degrees instead of 22 degrees as with cub wings. I would think the person who built the fuselage would have set it up this way if the plan was to use Pacer wings. As dpkunkt mentioned, new custom struts will be needed because the strut attach point is different on a Cub and a Pacer so Pacer struts won't work. The aileron cables are routed differently and I believe the aileron horn is different on a Pacer. But it is definitely doable.

A Pacer would be easier and cheaper. But I would look for a Clipper with a bigger engine. If you want a Cub, you probably want Cub wings. Opinion.

If you decided you wanted cub wings, those Pacer wing parts could get you well on your way. A cub wing has 4 bays. A Pacer wing has 3. The missing Pacer bay is exactly one cub bay, so in a sense a Pacer wing is 3/4 of a cub wing in terms of ribs, drag wires and the like. It's true that some parts are beefed up in the Pacer wing because of the higher gross weight, but there is a lot of overlap. So, you could take the Pacer wing parts, get cub spars, buy about 4 ribs, a couple of drag wires for the missing bay, and a few odds and ends to assemble a passable cub wing for an experimental. The harder part would be rebuilding the flaps and ailerons to lengthen them.

Pacer and Colt wings on a homebuilt Cub have been done a few times before. You've just got to make up your mind if that is what you want or not.

I built one like you are considering with 0-235-L2C 115 HP flew great and I loved it. See cover and artical Sport Aviation Dec 2009.

Attached article. Nice airplane! You are using past tense. Did you sell it?

Yes I sold it in August, I have built A long wing LSA super cub with a 160 HP used alm struts wood prop got it at 890#. I have flown it 8 hrs and am happy with the performance so far.

We are going to need pictures of that new ship(please), your last one was as nice as they come. I took many pictures of it at Lee Bottom.

So..... please tell us why you got rid of that short winger in favour of a long wing Cub.

Thanks,
Andrew.

Kenneth, How was aileron response with the short aileron, short wing and long fuselage? I remember drooling over it at Oshkosh a few years ago. Nice workmanship.

 

[Alberta Cubber]

Thanks for the info guys. I think I might just make the trade. I looked into the spars and it would be relatively cheap to just buy new spars and a few ribs to have full length wings. I live on the prairies so I may just try the short wings for speed and see how I like them. But as the one of the first comments mentioned, those oversize and over weight wing tips have got to go. With those big wing tips and for how much they weigh, a person would have been better off with a short spar extension and a couple more ribs.

 

[Cub junkie]

You might consider an extension like the Stewart's. Those wittman style wingtips worked good on the homebuilt they were designed for but I don't see them doing much for a 90 to 100 mph airplane with a USA 35B airfoil. Strictly a guess on my part.

Let's see some fuselage photos. How does that look?

Hi All If you use the pacer -tri-pacer wings even with extened wing tips your slowR speed glide is still the glilde angle of brick . If you what a supercub by all means make the supercub wings. Ron

Here are a few more pictures that I took with my phone when I stopped in to see the project. I was in a hurry (had 4 hours to drive still) and didn't take many good pictures. I'll have to drive down and see it again before I make the deal. He's going on vacation for a couple weeks so I have time to decide. There is some minor surface rust from sitting outside for a bit but no pitting or anything too bad. Again i'd have to take a friend along who has worked on a few cubs to have a look at it. The flaps got a little storage rash as everything was not so neatly packed into the fuse. There's everything from cables, instruments, engine, new windshield and spares to go with it.
