New Pacific Aeromodel Clip Wing Monocoupe
 

I stopped by Pacific Aeromodels today and look what I saw! It is 25% scale and weighs 14 pounds with a G26 in it. They say it flys like a sport pattern plane. They told me it will be at the AMA convention in Ontario this weekend.

I like the color scheme and how they supplied decals! I wonder how it compares quality-wise with the Kangke/Supercraft 1/4 Monocoupe long-span version. With that short wing, I'm sure its a bit less "Trainer" and more "Intermediate Sport-Flyer" than the Kangke version.

I just checked their website and it hasn't been updated with the new model info yet. Would love to find out other details such as availability and price. Thanks for the heads-up!

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

That is a really good looking airplane!

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

I have the GeeBee Y and they make good stuff. that is a good looking plane for sure. What are the specs?... anyone?

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

I'll check it out at the show and let you know.

Jim Johnson from Pacific Aeromodel was kind enough to get back to me with some info on the new Clipped-Wing Monocoupe ARF. He said that he expects them to be in stock this March. Seems like a beauty for the price...It's got me thinking of putting a big Axi electric in mine. Here is the info he sent me:

_______________________________________

"Race pilot Johnny Livingston created the full scale Clip Wing Monocoupe in 1932 by clipping 9 feet off the wings of his standard Monocoupe and adding a 60% bigger engine. Before the war, the Clip Wing was a very successful racer, winning more races than all of the Gee Bees combined. After WWII, the Clip Wing was used for aerobatic competition and airshows where it was again extremely successful, winning the first world aerobatic championship in 1948.

Pacific’s Quarter scale replica captures the original’s tough good looks, but our designers have tamed it’s nature to the point where it is as easy to fly as any intermediate sport model. It is fully aerobatic, yet lands like a trainer. Superb quality, easy assembly and front or rear mounts for your servos to help with the balance. This model is a stand-out."

Specifications:

• Wing Span: 69 in.
• Overall length: 63.5 in.
• Wing Area: 950 sq. in.
• Flying Weight: 12.5-14 lb.
• Engine: 1.20-1.80 (glow), 25-35cc (gas).
• Radio: 4 Channel, 6 servos.

I saw it at the AMA show today. It's a beauty!!

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

that thing on floats would be dreamy

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Here are my pics. They say that their Clip Wing is easier to fly than the Kange full span Monocoupe.

Jim

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

If the numbers posted by bearzilla are correct I doubt it's a good flier.
At 13 pounds 3 ounces {middle of the weight range} with 950 sq in it would have a wing loading of 32 ounces per foot.
For a 69" span model that's not good, in fact it's appalling, my 26 pound 33% Extra with 106 inch span is only 30.
The Kangke model is only around 22 at 14.5 pounds.
I do like the looks, hope someone posts a flight report.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Here we go again!

I'd suggest you check this thread http://www.rcuniverse.com/forum/m_5002875/tm.htm on the Top Flight Cessna 310, which has the same wing area as the Clip Wing, weighs 20# plus, and has a wing loading of 50. That's too high for me, but there seems to be no problem with the way it flies.

I don't imagine that the Clip Wing will 3D like your Extra, nor will it float around like the Kange. On the other hand, 32 oz is a pretty good figure for a quarter scale airplane. There are plenty of ~1000 sq. in. aerobats out there with 30-35 ounce wing loadings and they fly fine. The Pacific Clip Wing is a lot bigger than the short wingspan might lead you to believe.

Jim

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Jim, these are quotes from the post you listed, your quotes: http://www.rcuniverse.com/forum/m_5002875/tm.htm

"Wing span has nothing to do with it. Wing area is the important factor. As wing area goes up, the airplane can support a higher wing loading. The 310 supposedly has a wing area of 948 sq. in. which would be about right for a 60 size trainer or a 90-120 size aerobat. Either of which would probably have a wing span of about 70 inches, putting them, and the Top Flight 310, squarely into your 25-30 oz category.
Jim"

I agree


"Great Planes seems to be moving toward great looking, unusual scale planes that are a real treat to look at, but "difficult" to fly. Personally, I wouldn't walk from the pits to the flight line for stick time on a twin with a 43-50 oz wing loading.
Jim "

I agree again


What is a good flier to one person may be terrible to another, I like my planes to be light on the wing and land at reasonable speeds.
I have a Yellow P-38, 80 inch span, 24 pounds, two Moki 2.1's, 37 oz/ft, beautiful airplane, makes ya drool to look at it, flies like crap.
It's hot. takes a lot of runway {wouldn't even consider flying off long grass}, and I know the first time an engine flames out will be the last time it flies.
After a 5 minute flight your sweating, NOT fun.
High wing loading means high pucker factor, I want to enjoy my time not work at it.
This is of course just my opinion

:)

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Outcast,
Surely you jest.:eek:

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

And I agree completely with you. I quess it just comes down to what you consider a "high" wing loading. I still wouldn't want to fly a 948 sq. in. twin with a 50 ounce loading, even if others say it flies fine, but a gas powered quarter scale airplane at 32 ounces would not bother me at all. (And Pacific's test pilot said that with flapperons down it lands at least as slow as the Kange.)

I look forward to the flight reports as well, but I think it will fly great.

I have the Kangke Monocoupe with a Roto 25, weighs just a click over 14 pounds, With flaps down this plane can go so slow you can walk out and catch it. I think "Pacific's test pilot" may be bending the truth just a tad.[sm=lol.gif]

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

The cowl looks like the right size on this Monocoupe, and the price on the sign says $429.00.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

I cant seem to get pacific aeromodeles to come up. is what maybe the web site. thank you builder jim

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

builder jim,

Here is the URL.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Wing area is only one issue in several factors, the other being rib profile or airfoil. A high lift clark Y type airfoil will produce more LIFT than a symetrical thin profile at any given area. High wing loaded airplanes almost always have a large amount of wash out to help keep pilots from Killing themselves.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

THANK YOU ZIPPI. have build several of these and are looking forward to the arf. builder jim

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Reading about the 1/4 scale clip wing from Pacific aero got me all excited. I was wondering why someone had not produced one. Sure hope they offer it uncovered.

I'm going to start on my Kangke 1/4 scale Monocoupe soon and have a question on engines. Considering the Saito 170 3 cyl radial or the OS 160 twin. Anyone with experience with either, please let me know.

Richard

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Has anyone seen a Video of this Monocoupe flying? This looks like a cool plane.

Does anyone have an opinion of this versus a Super Chipmunk ARF? (I am sure I will get opinions :))

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

:DAnybody get one yet?

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

The website shows that they're in stock, and my credit card was billed on 5/18 for the one I ordered at Toledo, so I'm guessing I'll have mine in the next few days.
Al

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Am ordering mine soon, just letting things settle here, hope you can start a building post. am modifying mine to exact out line and recovering in sigs aerocoat. have a saito 150 and os 120 but want to run the os160 twin. we'll see. jim

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Got mine yesterday. Have unpacked it and inspected it quickly. Based on that initial look, it seems to be well constructed and there are no wrinkles in the covering. None. A first for me. Robart-style hinges drilled and mounted on all the control surfaces, but not glued in place. A very simple and what appears to be a very effective wheelpant mount. Haven't checked out the hardware yet. The colors look very close to my Cox 1/5 Waco that I'm just now completing (If I ever get finished wrestling with THOSE gd wheelpant mounts!!!! [:@] [:@] !!!)
There's no instruction manual out. They told me it'd be available in a week or so and they'll send it to me. I'm not in any hurry as I have a couple of projects to finish up before I start on this one. I'm thinking of using an OS 160 or Saito 180 on it. Also have a Super Tigre 2300 waiting for a home.... I'll have to check the fit, weight and most particularly the balance, as there is very little nose moment, before I make a final decision.
Anyway, first impressions are very good.
Al

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Ok.. here it is.....I got one of the clip winged Monocoupes from Pacific Aeromodels. The miniute I saw a picture of this plane, I had to go pick it up right from their warehouse. Here is what I think:
The plane went together with no issues whatsoever. Fun to build, everything was there and fit right! Great quality. This plane looks amazing in person.

I took the plane for it's maiden flight a few days ago. It fly's GREAT! The plane got up on it's main wheels quickly, and took off smoothly. It was a blast to fly. I didn't do much with it on the first day as you might imagine. It tracks great, responds well, and you couldn't tip stall this thing if you tried. The landing was a piece of cake. Cut the throttle, let it sink, gave it a tiny bit of throttle and let it land. The advertising is true. It lands like a trainer.

A few tips for what it's worth:

1. Balance the plane right around the wing tube (bar).
2. Set up your throws exactly the way Pacific Aeromodels recommends. You won't be sorry.
3. I have a Saito 1.80 FS mounted inverted in mine. It works great.
4. Use silicone on the landing gear fairings. Works good and they won't crack.
5. I chose to put the rudder servos in the back of the fuselage. Just a personal preference. They give you the option of this method or to put them inside the plane for a more scale look.
6. I set up the plane with flaperons. I was going to use them, but the plane was landing so well on approach, I never used this option. I will give it a try next time. I am guessing it will land even easier.

Bottom line is that I think this may be the best all around plane I have owned.

Enjoy!

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

One more thing....Thanks to Pacific Aeromodels for the great service. Very much appreciated!

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Great report. Thanks. Couple of questions --
Do you know the all-up weight? And how much, if any, nose weight did you have to add to make it balance?

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

I am not sure about the total weight. With the Saito 1.80 it took exactly ZERO nose or tail weighting. Mine did wind up taking about one ounce of weight on the right wing tip. I do have a pretty large 5 cell battery on the left side of the fuse. This may be the reason. But other than that, no nose or tail weight was required.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

THAT's good news, as I'm planning on a Saito 180 or a ST 2300. W/ no added weight it ought to be right on spec.
Thanks
Al

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Here's my Clipped Wing Monocoupe just about ready to fly.

I'm using a FUJI 24EI gas engine and a Spektrum DX7 radio and 821 servos.

Finished weight is 13 pounds 4 ounces minus fuel.

It balanced perfectly at the spar with elevator servos at tail and rudder servo in cockpit.

But there's no @#$%^& wing area!!!

It should do just fine despite the fact that there is only 980 square inches of wing.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Petit:

There is a video on the website that seems to show it works just fine with no @$^^#$* wing area. ;)

Jim

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

I raised the wing area issue early on in another forum. Was told by someone who said he'd flown the plane that it landed very well w/ 15 degrees of "flaperon". Plus the video -- sure looks like it'll fly well! We'l see. I'll probably start mine in a couple of weeks. From the unpacking and inspection it sure looks good.
Al

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

I was just making a joke. This is a hobby. We all deserve a good laugh now and then.

But that doesn't make the wing area any larger...

LOL

I'm sure it'll do just fine.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Yep! And it doesn't!
Where will your review show up, Dick?
And will you give us at least a brief flight report here?
Thanks
Al

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

The full review will be in an upcoming issue of R/C REPORT but I'll let you know how it does as soon as the rain stops here and I get some time to fly the plane.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Looks awesome. I just got mine and will be starting it shortly. Any modifications needed on mounting the Fuji engine? I have never had one so will be anxiously waiting your flight report. What prop are you using? Have you had much experience with Fuji engines? I assume it has electronic ignition. Good luck.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

I had to make up some 3/4" standoffs to get the prop hub in the right place and the fuselage needed a little notch to clear the muffler.

Fuji engines are pretty good, decent power, relatively quiet.

I'm starting with an 18-6 but may drop back one size if necessary. Yes, electronic ignition.

RE: New Pacific Aeromodel Clip Wing Monocoupe
 

Here's an update to the Addendum in the instruction manual.

(Guess who did it wrong?)

"The Monocoupe has a small amount of dihedral in each wing. This is
strictly for appearance, since a straight wing will appear to droop. Because
the aluminum wing joiner has this dihedral in it, it is possible to install it
upside down, and if it is installed upside down, the wing struts will not fit.
Please be sure that the aluminum wing joiner is installed with the dihedral
“V” facing UP."

(Use a 36" metal ruler to find the "V". It's really there)
